This oil pollution contains numerous impurities, heavy metals, and organic pollutants, making it highly polluting. If not treated or disposed of promptly, it will cause serious environmental damage.
[0003] Currently, the main methods for treating heavy oil pollution include physical, chemical, and biological methods. Physical methods, such as centrifugation, filtration, and flotation, can achieve a certain degree of oil-water separation.

[0020] To address the aforementioned problems, the present invention also provides a computer-readable storage medium storing at least one instruction, which is executed by a processor in an electronic device to implement the aforementioned method for treating heavy oil pollution based on three-phase separation.
[0021] To address the problems described in the background section, this invention identifies the heavy oil pollution to be treated and performs preliminary testing to obtain initial water content, initial metal content, and initial viscosity. Thus, this invention, by first understanding the basic properties of the raw material and identifying key indicators such as moisture, impurities, and flowability, provides a scientific basis for selecting appropriate treatment methods, thereby obtaining... Each test group, for Each test group in the experiment performed the following operations: Sampling of the heavy oil to be treated was conducted to obtain heavy oil samples. This embodiment of the invention, by preparing multiple sets of different treatment conditions for the same batch of raw materials and conducting small-scale "experiments," sought the optimal process through parallel comparison. Based on the test group, initial moisture content, initial metal content, and heavy oil samples, a sample treatment score was determined. This embodiment of the invention quantifies and scores the effectiveness of each experimental scheme, intuitively comparing the advantages and disadvantages of different treatment methods, and summarizing the sample treatment scores to obtain multiple sample treatment scores. This embodiment of the invention, by centralizing all experimental results to form a clear "report card," facilitates comprehensive evaluation and improves the treatment effect and treatment efficiency of the heavy oil treatment process. To improve the treatment quality, the best sample score is determined based on multiple sample treatment scores. This best sample score is the highest among the multiple sample scores. Therefore, this embodiment of the invention automatically selects the highest score from all "results," objectively identifying the most effective experimental scheme. The test group corresponding to the best sample score is designated as the optimal test group. This embodiment of the invention improves the treatment effect and quality of heavy oil pollution by determining the best-performing scheme in small-scale experiments as the "optimal formula" for large-scale treatment. Based on the optimal test group, pretreatment raw materials are identified. This embodiment of the invention prepares and formulates special agents or materials for use before the core treatment process according to the determined "optimal formula." The three-phase separation mechanism is identified, comprising a three-phase separation device, a cyclone generator, and a heat exchanger. This embodiment of the invention prepares a core "production line" for separating oil, water, and solids. This equipment combination can efficiently complete physical separation. Based on the three-phase separation device, cyclone generator, and initial viscosity within the three-phase separation mechanism, basic separation parameters are determined. This embodiment of the invention sets a set of initial, universal operating parameters (such as temperature, pressure, and speed) for this "production line," allowing the equipment to start operating and improving the treatment effect and quality of the heavy oil pollution treatment process. Based on the pre-treated raw materials, the heavy oil pollution to be treated, the basic separation parameters, the three-phase separation device within the three-phase separation mechanism, and the cyclone generator within the three-phase separation mechanism... The heat exchanger in the three-phase separation mechanism confirms the presence of oil phase substances. This embodiment of the invention demonstrates that by feeding the pre-treated raw materials into a device with pre-set parameters for formal separation, a preliminary purified oil is obtained. The oil phase substances are then subjected to quality testing to obtain a quality score. This embodiment of the invention improves the treatment effect and quality of the heavy oil pollution process by performing a "quality check" on the initially separated oil to see if its purity, water content, etc., meet the standards and using a score to measure this. Based on the quality test score and basic separation parameters, corrected separation parameters are determined. This embodiment of the invention intelligently fine-tunes the operating parameters of the equipment (such as slightly increasing the temperature or changing the rotation speed) according to the "quality check" score, further improving the separation effect.Based on the modified separation parameters, the three-phase separation mechanism, and the identification of the final oil phase substances, the treatment of heavy oil pollution is completed. It is evident that this invention, through secondary or advanced treatment of the oil phase substances using optimized parameters, ultimately produces high-quality, standard-compliant recovered oil, completing the entire treatment process from waste oil to clean oil, thus improving the treatment effect and quality of heavy oil pollution treatment. Therefore, this invention can improve the treatment effect and quality of heavy oil pollution treatment. Attached Figure Description

[0028] Reference Figure 1 The diagram shown is a schematic flow chart of a heavy oil pollution treatment method based on three-phase separation according to an embodiment of the present invention. In this embodiment, the heavy oil pollution treatment method based on three-phase separation includes: S1. Identify the heavy oil to be treated and perform preliminary testing on the heavy oil to be treated to obtain the initial water content, initial metal content and initial viscosity.
[0029] For example, Xiao Zhang is a worker at a heavy oil waste treatment plant. He needs to treat the heavy oil waste in the plant and extract oil phase substances from it to achieve the resource-based treatment of heavy oil waste. Therefore, Xiao Zhang identifies the heavy oil waste to be treated, which provides a basis for the subsequent extraction of oil phase substances from the heavy oil waste.
[0030] It should be explained that heavy waste oil refers to the waste oil that has failed during the storage, dehydration, gathering and transportation and tank cleaning of crude oil, while heavy waste oil to be treated refers to heavy waste oil that needs to be treated.
[0031] Specifically, the preliminary testing of the heavy oil to be treated to obtain the initial water content, initial metal content, and initial viscosity includes: Multiple samples were taken from the heavy oil pollution to be treated to obtain multiple test samples; For each of the multiple test samples, perform the following operation: The first moisture content was confirmed based on the tested samples; The metal content of the test sample was determined to obtain the first metal content; The viscosity of the test sample was measured to obtain the first viscosity.
[0032] By summing up the first moisture content, the first metal content, and the first viscosity, multiple first moisture contents, multiple first metal contents, and multiple first viscosities are obtained; The initial moisture content, initial metal content, and initial viscosity are determined based on multiple first moisture contents, multiple first metal contents, and multiple first viscosities, wherein the initial moisture content is the average of multiple first moisture contents, the initial metal content is the average of multiple first metal contents, and the initial viscosity is the average of multiple first viscosities.
[0033] It should be explained that the multiple sampling of the heavy oil to be treated refers to randomly extracting multiple samples of a certain mass (e.g., 500g) of heavy oil from the heavy oil to be treated. These samples are the test samples. The determination of the metal content of the test samples refers to determining the metal content in the test samples using a metal determination method (e.g., atomic absorption spectrometry). The method for determining the metal content in the test samples using a metal determination method (e.g., atomic absorption spectrometry) is existing technology and will not be described in detail here. The metal content in the test samples is the first metal content. The viscosity test of the test samples refers to measuring the viscosity of the test samples using a viscosity testing device (e.g., a rotational viscometer). The method for measuring the viscosity of the test samples using a viscosity testing device (e.g., a rotational viscometer) is existing technology and will not be described in detail here. The viscosity of the test samples is the first viscosity.
[0034] Specifically, the determination of the first moisture content based on the tested sample includes: Confirm the quality of the test sample and obtain the distillation apparatus, moisture receiver, and camera; The moisture receiver was photographed using a camera to obtain the original image; The test sample is added to the distillation apparatus to obtain the target distillation apparatus; Once the target distillation time is identified, multiple distillation times are obtained by uniformly sampling the target distillation time based on a preset time interval. The target distillation apparatus is heated, and the time is recorded in real time starting from the time of heating the target distillation apparatus to obtain the distillation time. A moisture receiver is used to collect moisture from the target distillation apparatus during the heating process to obtain the target moisture receiver. Extracting the first from multiple distillation times The distillation time and the first Distillation time, of which, The initial value is 1; When the distillation time is equal to the first During each distillation time, the target moisture receiver is photographed using a camera to obtain the first liquid surface image; When the distillation time is equal to the first During each distillation time, the target moisture receiver is photographed using a camera to obtain a second liquid surface image; The first test water content was confirmed based on the quality of the test sample, the original image, and the first liquid surface image. The second test water content was confirmed based on the quality of the test sample, the original image, and the second liquid surface image. Compare the first test moisture content and the second test moisture content. If the second test moisture content is less than or equal to the first test moisture content, then the first moisture content is determined based on the second test moisture content and the first test moisture content. The first moisture content is the average of the first test moisture content and the second test moisture content. If the moisture content of the second test is greater than the moisture content of the first test, then let ,Will As Returning to the extraction of the first from multiple distillation times The distillation time and the first The distillation time is adjusted until the second test moisture content is less than or equal to the first test moisture content.
[0035] It should be explained that the distillation apparatus is a distillation flask; optionally, a round-bottom distillation flask is used. The moisture receiver is a Dean-Stark device; optionally, the FY-ZLY6B universal six-in-one distillation device from Feiyue Instruments is used. The camera is a camera; optionally, a Canon 6D is used. The phrase "using the camera to photograph the moisture receiver" refers to taking an image of the side of the moisture receiver. The method of taking this image is existing technology and will not be elaborated here. The image of the side of the moisture receiver is the original image. "Sample quality" refers to the weight of the sample. "Adding the sample to the distillation apparatus" means adding the sample to the distillation apparatus. The target distillation apparatus refers to the distillation apparatus with the sample added. The target distillation time is a pre-set time for distilling the sample; optionally, it can be set based on the longest historical distillation test time for the sample. For example, if the longest historical distillation test time for the sample is 1 hour, the target distillation time can be set to 1 hour.
[0036] Understandably, the time interval is a value manually set by the staff of the heavy oil waste treatment plant based on the weight of the test sample. Optionally, if the weight of the test sample is less than 500g, the time interval is 5 seconds; if the weight of the test sample is greater than 500g and less than 1000g, the time interval is 10 seconds; and if the weight of the test sample is greater than or equal to 1kg, the time interval is 15 seconds. Heating the target distillation device refers to heating the target distillation device using a heating tool (e.g., an alcohol lamp). The method of heating the target distillation device using a heating tool (e.g., an alcohol lamp) is existing technology and will not be elaborated here. Collecting moisture from the target distillation device using a moisture receiver refers to collecting the water vapor generated by the target distillation device using a moisture receiver. The target moisture receiver is a moisture receiver that collects the water vapor generated by the target distillation device.
[0037] For example, if the heating time of the target distillation apparatus is 10:00:00, then when the time is 10:00:10, the distillation time is 10 seconds, and when the time is 10:10:00, the distillation time is 10 minutes. If the target distillation time is 5 minutes and the time interval is 1 minute, then after uniformly sampling the target distillation time based on the preset time interval, the multiple distillation times obtained are: 1 minute, 2 minutes, 3 minutes, 4 minutes, and 5 minutes. The second distillation time extracted from these multiple distillation times is 2 minutes, and the third distillation time is 3 minutes.
[0038] It should be explained that, "using a camera to photograph the target moisture receiver" means: using a camera to photograph an image of the side of the target moisture receiver; the first liquid surface image refers to the image taken when the distillation time is equal to the... The second liquid level image refers to the image taken by a camera at the side of the target moisture receiver during the first distillation time. The image of the side of the target moisture receiver is taken by a camera during the distillation time, and the method of taking the image of the side of the target moisture receiver by a camera is prior art and will not be described in detail here.
[0039] It should be understood that the method for determining the second test water content based on the sample quality, the original image, and the second liquid level image is the same as the method for determining the first test water content based on the sample quality, the original image, and the first liquid level image, and will not be repeated here. The method for determining the first test water content based on the sample quality, the original image, and the first liquid level image is described in subsequent embodiments. The second test water content refers to: when the distillation time is equal to the... The water content of the test sample was measured at each distillation time.
[0040] Specifically, the step of confirming the first test water content based on the sample quality, the original image, and the first liquid surface image includes: Edge detection is performed on the original image to obtain the initial liquid surface line; The initial pixel ordinates were determined based on the original image and the initial liquid level line. Edge detection is performed on the first liquid surface image to obtain the first liquid surface line; The ordinate of the first pixel is determined based on the first liquid surface image and the first liquid surface line; The height difference of the first pixel is calculated based on the initial pixel's ordinate and the first pixel's ordinate, using the following formula:
[0041] in, Indicates the height difference of the first pixel. Represents the initial pixel y-coordinate. Represents the y-coordinate of the first pixel; Obtain the pixel-to-quality conversion coefficient. Calculate the first test moisture content based on the pixel-to-quality conversion coefficient, the first pixel height difference, and the quality of the detected sample. The calculation formula is shown below:
[0042] in, This indicates the moisture content of the first test. Indicates the height difference of the first pixel. Represents the pixel-to-quality conversion factor. This indicates the quality of the tested sample.
[0043] It should be explained that the edge detection of the original image refers to the edge detection of the original image using an edge detection algorithm (such as the Canny operator). The method of using the edge detection algorithm (such as the Canny operator) to perform edge detection of the original image is existing technology and will not be described in detail here. The initial liquid surface line refers to the boundary line of the liquid surface in the original image obtained after edge detection of the original image.
[0044] It is understood that in this embodiment of the invention, the camera and the water receiver are fixed, and the camera is used to take pictures of the side of the water receiver. In all the pictures, the position of the water receiver in the image is relatively fixed. Only the position of the liquid surface in the water receiver changes. Here, the original image is simplified into a rectangle. A Cartesian coordinate system is established with the lower left corner of the rectangle corresponding to the original image as the origin, the long side of the rectangle as the y-axis, and the short side of the rectangle as the x-axis. The determination of the initial pixel ordinate based on the original image and the initial liquid surface line means: measuring the distance from the initial liquid surface line to the x-axis in the Cartesian coordinate system of the original image. The distance from the initial liquid surface line to the x-axis in the Cartesian coordinate system of the original image is the initial pixel ordinate. For example, if the distance from the initial liquid surface line to the x-axis in the Cartesian coordinate system of the original image is 10cm, then the initial pixel ordinate is 10.
[0045] It should be understood that the method for edge detection of the first liquid surface image is the same as the method for edge detection of the original image, and will not be repeated here. The first liquid surface line refers to the boundary line of the liquid surface in the first liquid surface image obtained after edge detection. The first pixel ordinate refers to the distance from the first liquid surface line to the x-axis in the Cartesian coordinate system of the first liquid surface image. The first pixel height difference refers to the distance between the first pixel ordinate and the initial pixel ordinate. The larger the first pixel height difference, the larger the distance between the first pixel ordinate and the initial pixel ordinate. The first test water content refers to the water content when the distillation time is equal to the first... The moisture content of the test sample is measured at each distillation time. The higher the moisture content of the first test sample, the higher the moisture content when the distillation time is equal to that of the second test sample. The greater the distillation time, the higher the water content of the test sample.
[0046] Specifically, obtaining the pixel-to-quality conversion coefficients includes: Obtain the target solution, weigh the target solution, and obtain the solution weight; A second moisture receiver is acquired, and a second original image is obtained by taking a picture of the second moisture receiver using a camera. Edge detection is performed on the second original image to obtain the second original liquid surface line; The second original ordinate was determined based on the second original image and the second original liquid level line. The target solution is added to the second moisture receiver to obtain the third moisture receiver; The third image is obtained by taking a picture of the third moisture receiver using a camera; Edge detection is performed on the third image to obtain the second liquid level line; The second vertical coordinate was determined based on the third image and the second liquid level line; The pixel-to-quality conversion factor is calculated based on the second original ordinate, the second ordinate, and the solution weight. The formula is shown below:
[0047] in, Represents the pixel-to-quality conversion factor. Indicates the weight of the solution. Indicates the second ordinate. This represents the second original ordinate.
[0048] It should be explained that the target solution refers to distilled water, and weighing the target solution means measuring its weight using a weighing tool (e.g., a scale). The weight of the target solution is the solution weight. The second moisture receiver refers to a Dean-Stark device that has the same shape and size as the moisture receiver. Taking a picture of the second moisture receiver with a camera means taking an image of the side of the second moisture receiver. The method of taking this image is existing technology and will not be described further here. The image of the side of the second moisture receiver is the second original image.
[0049] It should be understood that the methods for edge detection of the second original image and the third image are the same as the methods for edge detection of the original image, and will not be repeated here. The second original liquid surface line refers to the boundary line of the liquid surface in the second original image obtained after edge detection of the second original image. The second liquid surface line refers to the boundary line of the liquid surface in the third image obtained after edge detection of the third image. The methods for determining the second original ordinate based on the second original image and the second original liquid surface line, and the methods for determining the second ordinate based on the third image and the second liquid surface line, are the same as the methods for determining the initial pixel ordinate based on the original image and the initial liquid surface line, and will not be repeated here. The second original ordinate refers to the distance from the second original liquid surface line to the x-axis in the Cartesian coordinate system of the second original image, and the second ordinate refers to the distance from the second liquid surface line to the x-axis in the Cartesian coordinate system of the third image.
[0050] It is understood that the third moisture receiver refers to the second moisture receiver to which the target solution has been added. The phrase "using a camera to photograph the third moisture receiver" refers to taking an image of the side of the third moisture receiver using a camera. The method of taking an image of the side of the third moisture receiver using a camera is existing technology and will not be described in detail here. The image of the side of the third moisture receiver is the third image. The pixel-to-quality conversion coefficient is a constant used to convert the change in image pixels caused by the increase in collected moisture in the moisture receiver into the change in the actual increase in the mass of collected moisture.
[0051] S2, Obtain Each test group, for Each test group in the test group performs the following operation: taking samples of the heavy oil to be treated to obtain heavy oil samples.
[0052] It should be explained that the sampling of the heavy oil to be treated means: extracting a certain mass (e.g., 500g) of heavy oil from the heavy oil to be treated, and the certain mass (e.g., 500g) of heavy oil is the heavy oil sample.
[0053] In detail, the acquisition The test group includes: After confirming the dosage ranges of the demulsifier and the metal removal agent, uniform sampling was performed on the demulsifier dosage range based on the preset demulsifier sampling interval. Dosage of demulsifier; Based on the preset sampling interval for the metal removal agent, uniform sampling is performed within the dosage range of the metal removal agent to obtain... Dosage of demetallizing agent; use Dosage of demulsifier and Obtain the dosage of the demetallizing agent. There are 10 test groups, among which... ,and, Each test group includes: one dosage of demulsifier and one dosage of metal remover.
[0054] It should be explained that a demulsifier is a surfactant that can break up emulsions (such as SP-type demulsifiers), while a demetallizer is an important chemical additive used in the petrochemical industry for heavy oil hydrogenation reactions. Its main function is to remove heavy metal components from the feedstock, protecting the activity of the main catalyst and extending its service life. The dosage range for both demulsifier and demetallizer is adjustable. Optionally, the sampling interval for demulsifier is 10 ppm, and the sampling interval for demetallizer is 20 ppm. The dosage ranges for both demulsifier and demetallizer can be obtained from the product technical manuals provided by the demulsifier and demetallizer manufacturers.
[0055] For example, if the demulsifier dosage range is 10-50 ppm and the demulsifier sampling interval is 10 ppm, then after uniformly sampling the demulsifier dosage range based on the preset demulsifier sampling interval, the resulting 5 demulsifier dosages are: {10 ppm, 20 ppm, 30 ppm, 40 ppm, 50 ppm}. If the demetallizer dosage range is 10-70 ppm and the demetallizer sampling interval is 20 ppm, then after uniformly sampling the demetallizer dosage range based on the preset demetallizer sampling interval, the resulting 4 demulsifier dosages are: {10 ppm, 30 ppm, 50 ppm, 70 ppm}. By cross-combining the 5 and 4 demulsifier dosages, 20 test groups are obtained: {(10 ppm, 10 ppm), (10 ppm, 30 ppm), ..., (50 ppm, 50 ppm), (50 ppm, 70 ppm)}.
[0056] S3. Based on the test group, initial moisture content, initial metal content, and heavy oil sample, the sample treatment score is determined. The sample treatment scores are summarized to obtain multiple sample treatment scores. Based on the multiple sample treatment scores, the best sample score is determined. The best sample score is the sample treatment score with the largest sample score among the multiple sample scores. The test group corresponding to the best sample score is taken as the optimal test group.
[0057] In detail, the sample treatment score determined based on the test group, initial moisture content, initial metal content, and heavy oil sample includes: Confirm the test weight of the heavy oil sample; The target demulsifier and target demetallizer were identified based on the test weight and the dosage of demulsifier and demetallizer in the test group. The heavy oil sample, the target demulsifier, and the target demetallizing agent are mixed to obtain the sample to be separated; The sample to be separated was subjected to three-phase separation to obtain a simulated oil phase; The simulated oil phase was analyzed to obtain the simulated water content and simulated metal content; The sample treatment score is calculated based on the initial moisture content, simulated moisture content, initial metal content, and simulated metal content, using the following formula:
[0058] in, Indicates the sample processing score. This represents the simulated moisture content. Indicates the initial moisture content. Indicates simulated metal content, This indicates the initial metal content.
[0059] It should be explained that the test weight refers to the weight of the heavy oil sample. The determination of the target demulsifier and target demetallizer based on the test weight and the dosages of demulsifier and demetallizer in the test group means: First, determine the test weight of the heavy oil sample to be treated, for example, 500g. The dosages of demulsifier and demetallizer in the test group are given as parts per million (ppm) of the sample weight, for example, 2 ppm for demulsifier and 2 ppm for demetallizer. Multiplying the test weight by the two dosage ratios respectively yields the specific mass of demulsifier and demetallizer to be added. For example: demulsifier mass = 500g × 2 ppm, demetallizer mass = 500g × 1 ppm. These two calculation results are the actual dosage of the target demulsifier and the actual dosage of the target demetallizer. Finally, weigh out the demulsifier by mass and the demetallizer by mass. The demulsifier by mass is the target demulsifier, and the demetallizer by mass is the target demetallizer.
[0060] It is understood that the sample to be separated refers to the mixture obtained by mixing the heavy oil sample, the target demulsifier, and the target demetallizer. The three-phase separation of the sample to be separated refers to the separation of the sample using a three-phase separation device (e.g., a three-phase separator). The simulated oil phase refers to the oil phase obtained after separating the sample using a three-phase separation device (e.g., a three-phase separator). The method of separating the sample using a three-phase separation device (e.g., a three-phase separator) is existing technology and will not be described in detail here.
[0061] It should be understood that the detection of the simulated oil phase refers to: confirming the water content of the simulated oil phase based on the simulated oil phase, and determining the metal content of the simulated oil phase to obtain the metal content in the simulated oil phase. The water content of the simulated oil phase is the simulated water content, and the metal content in the simulated oil phase is the simulated metal content. The method for confirming the water content of the simulated oil phase is the same as the method for confirming the first water content based on the test sample, and will not be repeated here. The method for determining the metal content of the simulated oil phase is the same as the method for determining the metal content of the test sample, and will not be repeated here. The sample processing score reflects the overall decontamination effect of heavy oil treatment; the higher the sample processing score, the better the overall decontamination effect of heavy oil treatment.
[0062] S4. Based on the optimal test group, the pre-treated raw materials were identified, and the three-phase separation mechanism was identified. The three-phase separation mechanism includes: a three-phase separation device, a cyclone generator, and a heat exchanger.
[0063] Specifically, the pre-treated raw materials identified based on the optimal test set include: Weigh the heavy oily waste to be treated to obtain the treated weight; The demulsifier and demetallizer were identified based on the treatment weight, the dosage of demulsifier and the dosage of demetallizer in the optimal test group; The heavy waste oil to be treated is heated based on a preset heating temperature to obtain heated heavy waste oil. Acquire a mixer and identify a first target mixer based on a preset first mixing speed; The demulsifier and the heated heavy waste oil were mixed using the first target mixer to obtain a preliminary mixture. The initial mixture is heated based on the heating temperature to obtain a heated mixture. The second target mixer is identified based on the preset second mixing speed; The demetallizing agent and the heated heavy waste oil were mixed using a second target mixer to obtain a second mixture. The second mixed raw material is allowed to stand to obtain the pretreated raw material.
[0064] It should be explained that weighing the heavy oil to be treated refers to measuring the weight of the heavy oil to be treated using a weighing device (e.g., a scale). This weight is the treated weight. The method of measuring the weight of the heavy oil to be treated using a weighing device (e.g., a scale) is existing technology and will not be elaborated here. The method for determining the treatment demulsifier and treatment demetallizer based on the treated weight, the dosage of demulsifier and demetallizer in the optimal test group is the same as the method for determining the target demulsifier and target demetallizer based on the test weight and the dosage of demulsifier and demetallizer in the test group, and will not be elaborated here. The treatment demulsifier refers to the demulsifier used in three-phase separation treatment, and the treatment demetallizer refers to the demetallizer used in three-phase separation treatment. The heating treatment of the heavy waste oil based on a preset heating temperature refers to using a heating tool (e.g., an electromagnetic heater) to heat the heavy waste oil to a predetermined temperature. This temperature is manually set by the staff of the heavy waste oil treatment plant based on twice the ambient temperature. For example, if the ambient temperature is 30 degrees Celsius, the heating temperature is 60 degrees Celsius. Heated heavy waste oil refers to the heavy waste oil after heating treatment.
[0065] It should be understood that the mixer is a mechanical agitator, and optionally, a German IKA RW20-digital digital display top-mounted cantilever mechanical agitator is used. The first target mixer refers to the mixer whose rotational speed of the agitator rod is set to a first mixing speed during operation. This first mixing speed is manually set by the staff of the heavy waste oil treatment plant based on the average mixing speed of multiple mixers historically recorded when mixing demulsifiers and heavy waste oil. For example, if the average mixing speed of multiple mixers historically recorded when mixing demulsifiers and heavy waste oil is 100 rpm, then the first mixing speed is 100 rpm. The preliminary mixture refers to the mixture obtained after mixing the demulsifier and the heated heavy waste oil. The method of heating the preliminary mixture based on the heating temperature is the same as the method of heating the heavy waste oil to be treated based on a preset heating temperature, and will not be repeated here. The heated mixture refers to the preliminary mixture after heating treatment. The second target mixer refers to a mixer in which the rotation speed of the stirring rod is set to a second stirring speed during operation. This second stirring speed is manually set by the staff of the heavy oil treatment plant based on the average stirring speed of multiple mixers historically recorded when mixing demetallizing agents and heavy oil. For example, if the average stirring speed of multiple mixers historically recorded when mixing demetallizing agents and heavy oil is 50 revolutions per minute, then the second stirring speed is 50 revolutions per minute. The second mixture refers to the mixture obtained after mixing the demetallizing agent and the heated heavy oil. The phrase "setting the second mixture to stand" means allowing the second mixture to stand until its temperature reaches ambient temperature. The pre-treated material refers to the second mixture after this settling process.
[0066] Understandably, a three-phase separation mechanism refers to a device that includes a three-phase separation unit, a cyclone generator, and a heat exchanger, used to separate heavy oily waste. The three-phase separation unit is a type of three-phase separator; optionally, a Qinglan Environment fully automatic oil-water separator can be used as the three-phase separation unit. The cyclone generator is a type of cyclone generator; optionally, a Haiwang FX hydrocyclone generator can be used as the cyclone generator. The heat exchanger is a plate heat exchanger; optionally, a Ruipute detachable plate heat exchanger can be used as the heat exchanger.
[0067] S5. Based on the three-phase separation device, cyclone generator and initial viscosity in the three-phase separation mechanism, the basic separation parameters are determined. Based on the pretreated raw material, the heavy waste oil to be treated, the basic separation parameters, the three-phase separation device in the three-phase separation mechanism, the cyclone generator in the three-phase separation mechanism and the heat exchanger in the three-phase separation mechanism, the oil phase substance is determined.
[0068] In detail, the basic separation parameters are determined based on the three-phase separation device, cyclone generator, and initial viscosity in the three-phase separation mechanism, including: The basic heating temperature is calculated based on the initial viscosity, using the following formula:
[0069] in, Indicates the base heating temperature. This indicates the preset standard processing temperature. Indicates the initial viscosity. This indicates the preset standard viscosity. This is the preset temperature adjustment coefficient; The basic feed flow rate was determined based on the initial moisture content and the three-phase separation device. Based on the initial metal content and the swirling generator, the basic inlet pressure and basic swirling intensity were determined. The basic separation parameters are obtained by summarizing the basic heating temperature, basic feed flow rate, basic inlet pressure, and basic cyclone intensity.
[0070] It should be explained that the base heating temperature refers to the temperature at which the heat exchanger processes the pretreated raw material. The standard processing temperature is a value manually set by the staff of the heavy oil treatment plant based on the average temperature of multiple heat exchangers that have been operating normally in the past. For example, if the average temperature of multiple heat exchangers that have been operating normally in the past is 20 degrees Celsius, then the standard processing temperature is 20 degrees Celsius. The standard viscosity is a value manually set by the staff of the heavy oil treatment plant based on the average viscosity of multiple heavy oils to be treated that have been recorded in the past. For example, if the average viscosity of multiple heavy oils to be treated that have been recorded in the past is 10 Pa·s, then the standard viscosity is 10 Pa·s.
[0071] It should be understood that the temperature adjustment coefficient is determined based on the intrinsic physical relationship between the viscosity and temperature of heavy oil. For most oils, the relationship between viscosity and temperature follows the Arrhenius equation, meaning that viscosity decreases exponentially with increasing temperature. The standard processing temperature corresponds to the temperature at which a material with standard viscosity achieves ideal flowability. When the initial viscosity of the material is higher, the required temperature compensation to achieve the same flowability (i.e., equivalent to reducing the viscosity to near the standard viscosity) is... This can be estimated using industry-standard viscosity-temperature curves. As a standardized and simplified calculation, the temperature regulation coefficient is derived from the following theoretical formula:
[0072] in, It refers to the reciprocal of the derivative of the viscosity-temperature curve at standard viscosity, and its physical meaning is "the temperature increase required to reduce viscosity by one unit".
[0073] It is understood that determining the basic feed flow rate based on the initial moisture content and the three-phase separation device means: determining the flow rate at which the pretreated raw material and the heavy oil to be treated are input into the three-phase separation device based on the initial moisture content and the rated flow rate of the three-phase separation device. This flow rate is the basic feed flow rate. Specifically, when the initial moisture content is high (above 8%), the feed flow rate needs to be appropriately reduced to ensure sufficient residence time for effective separation. Conversely, when the initial moisture content is low (below 5%), the feed flow rate can be increased to improve processing capacity. For example, if the rated flow rate of the three-phase separation device is 15 L / min, when the initial moisture content exceeds 8%, the basic feed flow rate is set to 80% of the rated flow rate, i.e., 12 L / min; when the initial moisture content is below 5%, the basic feed flow rate is set to 100% of the rated flow rate. The rated flow rate of the three-phase separation device can be obtained from the product technical manual provided by the three-phase separation device manufacturer.
[0074] It should be understood that the determination of the basic inlet pressure and basic swirling intensity based on the initial metal content and the swirling generator refers to determining the inlet pressure and swirling intensity of the swirling generator when processing the pretreated raw materials and the heavy oil to be treated, based on the initial metal content, the standard inlet pressure of the swirling generator, and the standard swirling intensity of the swirling generator. The inlet pressure of the swirling generator when processing the pretreated raw materials and the heavy oil to be treated is the basic inlet pressure, and the swirling intensity of the swirling generator when processing the pretreated raw materials and the heavy oil to be treated is the basic swirling intensity. Specifically, when the initial metal content is high (above 0.4%), it is necessary to increase the inlet pressure and swirling intensity to enable more efficient separation of solid particles and metal particles in the oil phase under centrifugal force. Conversely, when the initial metal content is low (below 0.2%), the inlet pressure and swirling intensity can be appropriately reduced to decrease energy consumption. For example, if the standard inlet pressure of the cyclone generator is 0.3 MPa and the standard cyclone intensity coefficient is 0.70, when the initial metal content exceeds 0.4%, the inlet pressure is increased to 0.4 MPa and the cyclone intensity coefficient is increased to 0.75. When the initial metal content is below 0.2%, the inlet pressure and cyclone intensity remain at the standard values. The standard inlet pressure and standard cyclone intensity of the cyclone generator can be obtained from the product technical manual provided by the cyclone generator manufacturer. The basic separation parameters refer to the data obtained by summing up the basic heating temperature, basic feed flow rate, basic inlet pressure, and basic cyclone intensity.
[0075] Specifically, the identification of the oil phase substances based on the pretreated raw material, the heavy waste oil to be treated, the basic separation parameters, the three-phase separation device in the three-phase separation mechanism, the cyclone generator in the three-phase separation mechanism, and the heat exchanger in the three-phase separation mechanism includes: The pretreated raw materials are mixed with the heavy waste oil to be treated to obtain the heavy waste oil to be separated; The target heat exchanger was identified based on the basic heating temperature in the basic separation parameters and the heat exchanger in the three-phase separation mechanism. The target heat exchanger is used to heat the heavy waste oil to be separated, and the heated heavy waste oil is obtained. The target swirling generator was identified based on the basic inlet pressure, basic swirling intensity, and the swirling generator in the three-phase separation mechanism among the basic separation parameters. The heated heavy waste oil was centrifuged using a target cyclone generator to obtain the initial enriched material. The target three-phase separation device was identified based on the basic feed flow rate in the basic separation parameters and the three-phase separation device in the three-phase separation mechanism. The initial enriched material was separated using a target three-phase separation device to obtain the oil phase.
[0076] It should be explained that the heavy waste oil to be separated refers to the heavy waste oil obtained after mixing the pretreated raw material with the heavy waste oil to be treated. The target heat exchanger refers to the heat exchanger in a three-phase separation mechanism where the temperature is set to the base heating temperature in the basic separation parameters. The phrase "using the target heat exchanger to heat the heavy waste oil to be separated" means heating the heavy waste oil to be separated using the target heat exchanger. The heated heavy waste oil refers to the heavy waste oil to be separated after undergoing the heated treatment. The target cyclone generator refers to the cyclone generator in a three-phase separation mechanism where the inlet pressure and cyclone intensity are set to the base inlet pressure and base cyclone intensity in the basic separation parameters. The phrase "using the target cyclone generator to centrifuge the heated heavy waste oil" means centrifuging the heated heavy waste oil using the target cyclone generator. The initially enriched substances refer to the oil phase and solid phase obtained after further centrifugation of the heated heavy waste oil.
[0077] Understandably, the target three-phase separation device refers to the three-phase separation device in a three-phase separation mechanism that sets the feed flow rate as the basic feed flow rate in the basic separation parameters. The separation of the initial enriched material using the target three-phase separation device refers to separating the oil phase and solid phase in the initial enriched material using the target three-phase separation device; the oil phase is the oil phase remaining after separating the oil phase and solid phase from the initial enriched material.
[0078] S6. Perform quality testing on the oil phase substances to obtain a quality test score, and confirm the corrected separation parameters based on the quality test score and the basic separation parameters.
[0079] In detail, the quality testing of the oil phase substances to obtain a quality test score includes: Oil phase substances are sampled to obtain test oil samples; The water content of the tested oil sample was tested to obtain the final water content; The metal content of the tested oil sample was determined by testing it to obtain the final metal content. The viscosity of the tested oil sample was measured to obtain the final viscosity. The quality inspection score is calculated based on the final water content, final metal content, final viscosity, preset standard oil phase water content, preset standard oil phase metal content, and preset standard oil phase viscosity. The calculation formula is as follows:
[0080] in, This indicates the quality inspection score. Indicates the final moisture content. Indicates the final metal content, indicating Final viscosity, Indicates the water content of the standard oil phase. Indicates the metal content of the standard oil phase. Indicates the standard oil phase viscosity. This indicates taking the larger function.
[0081] It should be explained that sampling the oil phase material refers to extracting a certain mass (e.g., 50g) of oil phase material from it. This certain mass (e.g., 50g) of oil phase material is the test oil sample. The method for testing the water content of the test oil sample is the same as the method for confirming the first water content based on the test sample, and will not be repeated here. The final water content refers to the water content of the test oil sample. The method for testing the metal content of the test oil sample is the same as the method for determining the metal content of the test sample, and will not be repeated here. The final metal content refers to the metal content in the test oil sample. The method for testing the viscosity of the test oil sample is the same as the method for testing the viscosity of the test sample, and will not be repeated here. The final viscosity refers to the viscosity of the test oil sample. The quality inspection score reflects the quality of the tested oil sample. The higher the quality inspection score, the better the quality of the tested oil sample, indicating a better effect of the three-phase separation treatment. In this embodiment of the invention, when calculating the quality inspection score based on the final water content, final metal content, final viscosity, preset standard oil phase water content, preset standard oil phase metal content, and preset standard oil phase viscosity, the units for the final water content and preset standard oil phase water content are %, the units for the final metal content and preset standard oil phase metal content are g / L, and the units for the final viscosity and preset standard oil phase viscosity are Pa·s. Furthermore, the final water content, final metal content, final viscosity, preset standard oil phase water content, preset standard oil phase metal content, and preset standard oil phase viscosity are all calculated using only the values in the above units.
[0082] Understandably, the standard oil phase water content is a value manually set by the staff of the heavy oil waste treatment plant based on the average water content of multiple historically treated and qualified oil samples. For example, if the average water content of multiple historically treated and qualified oil samples is 0.5%, then the standard oil phase water content is 0.5%. The standard oil phase metal content is a value manually set by the staff of the heavy oil waste treatment plant based on the average metal content of multiple historically treated and qualified oil samples. For example, if the average metal content of multiple historically treated and qualified oil samples is 1 g / L, then the standard oil phase metal content is 1 g / L. The standard oil phase viscosity is a value manually set by the staff of the heavy oil waste treatment plant based on the average viscosity of multiple historically treated and qualified oil samples. For example, if the average viscosity of multiple historically treated and qualified oil samples is 10 Pa·s, then the standard oil phase viscosity is 10 Pa·s.
[0083] Specifically, the process of determining the corrected separation parameters based on quality inspection scores and basic separation parameters includes: Compare the quality inspection score with a preset score threshold; If the quality inspection score is greater than or equal to the score threshold, the basic separation parameter will be used as the corrected separation parameter. If the quality test score is less than the score threshold, the final water content is compared with the standard oil phase water content. If the final water content is greater than the standard oil phase water content, the basic heating temperature in the basic separation parameters is increased according to the preset first step length to obtain the corrected heating temperature. The corrected feed flow rate is obtained by reducing the base feed flow rate in the base separation parameters according to the preset second step length. The basic inlet pressure and basic swirling intensity in the basic separation parameters are respectively used as the corrected inlet pressure and corrected swirling intensity; If the final water content is less than or equal to the standard oil phase water content, then compare the final metal content with the standard oil phase metal content. If the final metal content is greater than the standard oil phase metal content, then increase the basic inlet pressure and basic swirling intensity in the basic separation parameters according to the preset third step length to obtain the corrected inlet pressure and corrected swirling intensity. The basic heating temperature and the basic feed flow rate in the basic separation parameters are respectively used as the corrected heating temperature and the corrected feed flow rate; If the final metal content is less than or equal to the standard oil phase metal content, the final viscosity is compared with the standard oil phase viscosity. If the final viscosity is greater than the standard oil phase viscosity, the basic heating temperature in the basic separation parameters is increased according to the preset fourth step length to obtain the corrected heating temperature. The basic feed flow rate, basic inlet pressure, and basic cyclone intensity in the basic separation parameters are respectively used as the corrected feed flow rate, corrected inlet pressure, and corrected cyclone intensity; The corrected separation parameters are obtained by summarizing the corrected heating temperature, corrected feed flow rate, corrected inlet pressure, and corrected cyclone intensity. If the final viscosity is less than or equal to the standard oil phase viscosity, the basic separation parameters are used as the corrected separation parameters.
[0084] It should be explained that the scoring threshold is a value manually set by the staff of the heavy oil waste treatment plant based on the average quality inspection scores of multiple historically treated and qualified oil phases. For example, if the average quality inspection score of multiple historically treated and qualified oil phases is 85, then the scoring threshold is 85. The corrected separation parameter refers to the basic separation parameter when the quality inspection score is greater than or equal to the scoring threshold.
[0085] Understandably, increasing the base heating temperature in the basic separation parameters according to the preset first-step length means adding the first-step length to the base heating temperature in the basic separation parameters. The first-step length is manually set by the staff of the heavy oil treatment plant based on the temperature control accuracy of the heat exchanger. The temperature control accuracy of the heat exchanger can be obtained from the product technical manual provided by the heat exchanger manufacturer. Optionally, the first-step length is 1 degree Celsius. The purpose of increasing the base heating temperature by the first-step length is to reduce the viscosity and interfacial tension of the oil-water mixture by raising the temperature, thereby promoting the coalescence and sedimentation of water droplets and improving dehydration efficiency. The corrected heating temperature refers to the base heating temperature in the basic separation parameters after increasing it according to the first-step length. For example, if the base heating temperature in the basic separation parameters is 20 degrees Celsius and the first-step length is 1 degree Celsius, then the corrected heating temperature obtained after increasing the base heating temperature in the basic separation parameters according to the preset first-step length is 21 degrees Celsius.
[0086] It should be understood that reducing the basic feed flow rate in the basic separation parameters according to the preset second step length means subtracting the second step length from the basic feed flow rate in the basic separation parameters. The second step length is manually set by the staff of the heavy oil waste treatment plant based on the feed flow rate control accuracy of the three-phase separator. The feed flow rate control accuracy of the three-phase separator can be obtained from the product technical manual provided by the three-phase separator manufacturer. Optionally, the second step length is 1 L / min. Reducing the basic feed flow rate can prolong the residence time of the mixture in the three-phase separator, thereby improving the separation efficiency. The corrected feed flow rate refers to the basic feed flow rate in the basic separation parameters after being reduced according to the second step length. For example, if the basic feed flow rate in the basic separation parameters is 15 L / min and the second step length is 1 L / min, then after reducing the basic feed flow rate in the basic separation parameters according to the preset second step length, the obtained corrected feed flow rate is 14 L / min. The corrected inlet pressure refers to the basic inlet pressure in the basic separation parameters when the quality inspection score is less than the scoring threshold and the final water content is greater than the standard oil phase water content. The corrected vortex intensity refers to the basic vortex intensity in the basic separation parameters when the quality inspection score is less than the scoring threshold and the final water content is greater than the standard oil phase water content. In the above cases, only the basic heating temperature and basic feed flow rate are adjusted, because these two have the most direct impact on the dehydration effect. The basic inlet pressure and basic vortex intensity mainly affect the separation of metal particles, so they remain unchanged.
[0087] It should be explained that the methods for increasing the basic inlet pressure and basic swirling intensity of the basic separation parameters according to the preset third step length, and the methods for increasing the basic heating temperature of the basic separation parameters according to the preset fourth step length, are the same as the method for increasing the basic heating temperature of the basic separation parameters according to the preset first step length, and will not be repeated here. The third step length is manually set by the staff of the heavy oil treatment plant based on the control accuracy of the inlet pressure of the swirling generator. The control accuracy of the inlet pressure of the swirling generator can be obtained from the product technical manual provided by the swirling generator manufacturer. For example, if the control accuracy of the inlet pressure of the swirling generator is 0.1 MPa, then the third step length is 0.1. This step length can be used to adjust both the basic inlet pressure and the basic swirling intensity. Increasing the basic inlet pressure and basic swirling intensity enhances centrifugal force, thereby more effectively separating denser metal particles. The fourth step length is manually set by the staff of the heavy oil waste treatment plant based on twice the temperature control accuracy of the heat exchanger. The temperature control accuracy of the heat exchanger can be obtained from the product technical manual provided by the heat exchanger manufacturer. Optionally, the third step length is 0.1 degrees Celsius, and the fourth step length is 2 degrees Celsius. The corrected inlet pressure refers to the basic inlet pressure in the basic separation parameters after increasing the third step length. The corrected swirling intensity refers to the basic swirling intensity in the basic separation parameters after increasing the third step length. The corrected heating temperature refers to the basic heating temperature in the basic separation parameters when the quality inspection score is less than the scoring threshold, the initial water content is less than or equal to the standard oil phase water content, and the final metal content is greater than the standard oil phase metal content. The corrected feed flow rate refers to the basic feed flow rate in the basic separation parameters when the quality inspection score is less than the scoring threshold, the initial water content is less than or equal to the standard oil phase water content, and the final metal content is greater than the standard oil phase metal content.
[0088] Understandably, the corrected heating temperature refers to the base heating temperature after the fourth step of length increase. The corrected feed flow rate refers to the base feed flow rate in the basic separation parameters when the quality inspection score is less than the scoring threshold, the final water content is less than or equal to the standard oil phase water content, the final metal content is less than or equal to the standard oil phase metal content, and the final viscosity is greater than the standard oil phase viscosity.

The corrected separation parameters are the data obtained by summing up the corrected heating temperature, corrected feed flow rate, corrected inlet pressure, and corrected swirl intensity. The corrected separation parameters here are confirmed when the quality inspection score is less than the score threshold. Both the corrected separation parameters confirmed when the quality inspection score is greater than or equal to the score threshold are used to adjust the parameters of the subsequent three-phase separation device, but the confirmation methods are different.
[0089] S7. Based on the corrected separation parameters, the three-phase separation mechanism, and the oil phase substances, the final oil phase substances are identified, and the heavy oil pollution treatment is completed.
[0090] It should be explained that the determination of the final oil phase material based on the modified separation parameters, the three-phase separation mechanism, and the oil phase material means: adjusting the parameters of the three-phase separation mechanism using the modified separation parameters to obtain the adjusted three-phase separation mechanism, and then using the adjusted three-phase separation mechanism to separate the oil phase material to obtain the final oil phase, which is the final oil phase material.
[0091] For example, after obtaining the final oil phase material, Xiao Zhang extracted the useful oil phase material from the heavy oil to be treated, thus completing the treatment of the heavy oil.
[0092] It should be understood that the embodiments of the present invention also disclose a flowchart of the heavy oil pollution treatment process; please refer to the following for details. Figure 4 Specifically, it includes the following: testing the heavy oil pollution to be treated to obtain the initial water content, initial metal content, and initial viscosity, and using pre-obtained data... A test group was established, and the initial water content and initial metal content of the heavy oil to be treated were tested to obtain the optimal test group. The optimal test group was used to treat the heavy oil to obtain pretreated raw materials. The basic separation parameters were determined by using a pre-constructed three-phase separation mechanism and initial viscosity detection. The pretreated raw materials were separated using the three-phase separation mechanism and basic separation parameters to obtain oil phase substances. The quality test score of the oil phase substances was detected. The basic separation parameters were adjusted based on the quality test score to obtain corrected separation parameters. The oil phase substances were separated using the corrected separation parameters and the three-phase separation mechanism to obtain the final oil phase substances.
[0093] To address the problems described in the background section, this invention identifies the heavy oil pollution to be treated and performs preliminary testing to obtain initial water content, initial metal content, and initial viscosity. Thus, this invention, by first understanding the basic properties of the raw material and identifying key indicators such as moisture, impurities, and flowability, provides a scientific basis for selecting appropriate treatment methods, thereby obtaining... Each test group, for Each test group in the experiment performed the following operations: Sampling of the heavy oil to be treated was conducted to obtain heavy oil samples. This embodiment of the invention, by preparing multiple sets of different treatment conditions for the same batch of raw materials and conducting small-scale "experiments," sought the optimal process through parallel comparison. Based on the test group, initial moisture content, initial metal content, and heavy oil samples, a sample treatment score was determined. This embodiment of the invention quantifies and scores the effectiveness of each experimental scheme, intuitively comparing the advantages and disadvantages of different treatment methods, and summarizing the sample treatment scores to obtain multiple sample treatment scores. This embodiment of the invention, by centralizing all experimental results to form a clear "report card," facilitates comprehensive evaluation and improves the treatment effect and treatment efficiency of the heavy oil treatment process. To improve the treatment quality, the best sample score is determined based on multiple sample treatment scores. This best sample score is the highest among the multiple sample scores. Therefore, this embodiment of the invention automatically selects the highest score from all "results," objectively identifying the most effective experimental scheme. The test group corresponding to the best sample score is designated as the optimal test group. This embodiment of the invention improves the treatment effect and quality of heavy oil pollution by determining the best-performing scheme in small-scale experiments as the "optimal formula" for large-scale treatment. Based on the optimal test group, pretreatment raw materials are identified. This embodiment of the invention prepares and formulates special agents or materials for use before the core treatment process according to the determined "optimal formula." The three-phase separation mechanism is identified, comprising a three-phase separation device, a cyclone generator, and a heat exchanger. This embodiment of the invention prepares a core "production line" for separating oil, water, and solids. This equipment combination can efficiently complete physical separation. Based on the three-phase separation device, cyclone generator, and initial viscosity within the three-phase separation mechanism, basic separation parameters are determined. This embodiment of the invention sets a set of initial, universal operating parameters (such as temperature, pressure, and speed) for this "production line," allowing the equipment to start operating and improving the treatment effect and quality of the heavy oil pollution treatment process. Based on the pre-treated raw materials, the heavy oil pollution to be treated, the basic separation parameters, the three-phase separation device within the three-phase separation mechanism, and the cyclone generator within the three-phase separation mechanism... The heat exchanger in the three-phase separation mechanism confirms the presence of oil phase substances. This embodiment of the invention demonstrates that by feeding the pre-treated raw materials into a device with pre-set parameters for formal separation, a preliminary purified oil is obtained. The oil phase substances are then subjected to quality testing to obtain a quality score. This embodiment of the invention improves the treatment effect and quality of the heavy oil pollution process by performing a "quality check" on the initially separated oil to see if its purity, water content, etc., meet the standards and using a score to measure this. Based on the quality test score and basic separation parameters, corrected separation parameters are determined. This embodiment of the invention intelligently fine-tunes the operating parameters of the equipment (such as slightly increasing the temperature or changing the rotation speed) according to the "quality check" score, further improving the separation effect.Based on the modified separation parameters, the three-phase separation mechanism, and the identification of the final oil phase substances, the treatment of heavy oil pollution is completed. It is evident that this invention, through secondary or advanced treatment of the oil phase substances using optimized parameters, ultimately produces high-quality, standard-compliant recovered oil, completing the entire treatment process from waste oil to clean oil, thus improving the treatment effect and quality of heavy oil pollution treatment. Therefore, this invention can improve the treatment effect and quality of heavy oil pollution treatment.
