Description

Technical Field

[0001] The utility model relates to the field of oil blending equipment, in particular to an integrated device for quantitative blending and rapid testing of finished oil. Background Art

[0002] Petroleum refining is a key production area in the petrochemical industry. Crude oil is refined in refinery units into component oils with different distillation ranges. These component oils, as intermediate products in the refining process, while each possesses certain application value, are often not directly sold as finished oil products. This is because various finished oil grades on the market have very specific and stringent quality specifications, such as octane number, sulfur content, and flash point. However, component oils directly produced from production units often struggle to fully meet the quality standards for a specific finished oil grade. Some component oils may fail to meet the required quality standards in some quality indicators, while exceeding them significantly in others, resulting in a phenomenon of "excess quality."

[0003] To optimize resource utilization and meet market demand, refineries often adopt a "oil blending" strategy. This involves carefully selecting appropriate component oils from different production units based on the target product's quality specifications, then precisely calculating and blending the components. This process requires a high degree of expertise and precision, ensuring that the blended product fully meets the quality specifications of a specific oil grade, ensuring the product's market competitiveness.

[0004] However, in current refined oil blending practices, the process still relies heavily on operator experience and manual labor. Operators must manually adjust the proportions of the various component oils according to the blending table. This not only requires operators to monitor the table closely and closely monitor the blending progress, but can also easily lead to errors in the proper control of component raw material quantities, potentially causing the entire batch of refined oil to fail. Once a problem is discovered, even correcting it later requires significant manpower, material resources, and time, posing a challenge to the company's production efficiency and economic benefits.

[0005] Furthermore, after blending, refined oil products must undergo rigorous sampling and testing by laboratory technicians to verify that they meet established blending standards. This process is not only time-consuming, but if the test results show that the refined oil does not meet the standards, re-blending and re-testing are required, further increasing production costs and delays. Therefore, exploring and implementing more intelligent and automated refined oil blending and testing systems has become an urgent need for oil refineries to improve production efficiency, reduce costs, and enhance market competitiveness. Utility Model Content

[0006] The utility model provides an integrated device for quantitatively distributing and quickly testing refined oil, which aims to solve the problems existing in the prior art of over-reliance on the operator's experience and manual operation, which leads to imbalance in component ratios, the need for re-distribution, and waste of manpower and material resources.

[0030] The utility model provides an integrated device for quantitative blending and rapid testing of refined oil. After the operator quantitatively inputs the blending components, the operator controls the blending amount through a flow meter and is equipped with automatic testing until the indicators are qualified. The utility model solves the problems of the existing oil blending method, such as the easy occurrence of component ratio imbalance, the need for re-blending, and the waste of manpower and material resources.

[0031] like Figures 1-2As shown, the finished oil quantitative blending and rapid inspection device includes an oil blending module, a component analysis module, a real-time analysis module, and a control module. The component analysis module first analyzes the composition and quality of each component and then inputs the test results into the control module. The operator inputs the target parameters for oil blending into the control module, which automatically calculates the dosage of each component and activates the oil blending module. The oil blending module automatically mixes the component tanks into blending tank A according to the calculated parameters. After the raw material input is completed, it immediately enters the circulation mode and activates the real-time analysis module to monitor the circulating oil in real time. Once the monitoring is qualified, the oil blending is stopped and the oil is ready for sale. This not only avoids errors caused by human operation, but also improves production efficiency, reduces the fault tolerance rate, and reduces costs and increases efficiency for enterprises.

[0032] The oil blending module includes at least two group branches arranged side by side, a blending tank A and a mixing pump P6; the group branches all include component tanks, and the component tanks of each group branch are connected to the component analysis module, and the component tanks of each group branch are connected to the blending tank A in sequence through a flow regulating valve, a mass flow meter and a control pump; the inlet end of the mixing pump P6 is connected to the bottom of the blending tank A, and the outlet end of the mixing pump P6 is respectively connected to the inlet end of the blending tank A and the real-time analysis module, and the outlet end of the mixing pump P6 is also connected to the loading crane position in sequence through a flow regulating valve six V6 and a mass flow meter six F6.

[0033] Among them, the flow regulating valve is also called a self-operated balancing valve, a flow control valve, a flow controller, a dynamic balancing valve, and a flow balancing valve. It is an intuitive and simple flow regulating control device and is an existing technology.

[0034] The mass flow meter is an existing technology that performs measurements based on a variety of physical principles, including but not limited to the law of heat conduction, Newton's second law, and the principles of thermodynamics. It uses specific sensors, such as thermal sensors, differential pressure sensors, oscillating tube sensors, etc., to simultaneously measure the density and flow rate of the fluid, thereby calculating the mass flow rate.

[0035] Furthermore, an emergency shut-off valve is provided on the component branch, and the emergency shut-off valve is provided between the component tank and the flow regulating valve; the emergency shut-off valve is used to cut off the entire branch in an unexpected situation to prevent the situation from worsening.

[0036] Furthermore, a liquid level gauge L is provided on the blending tank A, which is used to monitor the liquid level in the blending tank A at all times. When the liquid level reaches the warning value, the emergency shut-off valve is closed by the control module to protect the blending tank A.

[0037] Furthermore, a pressure sensor is provided in the blending tank A, and the top of the blending tank A is connected to the oil and gas recovery system in the chemical plant through an oil and gas recovery valve.

[0038] There are five group branches in total. For the sake of convenience, the following description will take five group branches as an example. The five group branches are named group branch 1, group branch 2, group branch 3, group branch 4 and group branch 5 in sequence; group branch 1 is provided with group tank 1 A1, emergency shut-off valve 1 XCV1, flow regulating valve 1 V1, mass flow meter 1 F1 and control pump 1 P1 in sequence, group branch 2 is provided with group tank 2 A2, emergency shut-off valve 2 XCV2, flow regulating valve 2 V2, mass flow meter 2 F2 and control pump 2 P2 in sequence, and group branch 3 is provided with group tank 1 A2, emergency shut-off valve 2 XCV2, flow regulating valve 2 V2, mass flow meter 2 F2 and control pump 2 P2 in sequence.

[0039] The component tank A1, component tank A2, component tank A3, component tank A4 and component tank A5 are respectively connected to the component analysis module through pipelines to facilitate the component analysis module to detect and analyze the composition and quality of each component.

[0040] The oil blending module also includes a mixer 1 M1, a mixer 2 M2 and a mixer 3 M3.

[0041] Among them, the mixer is an existing technology, which is a device for mixing fluids of different properties. It is widely used in many fields such as petroleum, chemical industry, pharmaceuticals, and food.

[0042] like Figure 2As shown, the component analysis module and the real-time analysis module both include an automatic sampler, a filter, a constant temperature box, an automatic sample splitter, an automatic distillation range instrument, a nitrogen analyzer, a sulfur analyzer, a gas chromatograph, and an octane number analyzer; the component tank A1, component tank A2, component tank A3, component tank A4, and component tank A5 are respectively connected to the automatic sampler of the component analysis module via sampling circulation lines, and the outlet end of the mixing pump P6 is connected to the automatic sampler of the real-time analysis module via a sampling circulation line; there are six sampling circulation lines, each of which is provided with a circulation pump and a sampling valve; the supply pipe of the automatic sampler is connected to the automatic sample splitter in turn through a filter and a constant temperature box; the automatic sample splitter divides the sample into the automatic distillation range instrument, the nitrogen analyzer, the sulfur analyzer, the gas chromatograph, and the octane number analyzer; since the component analysis module and the real-time analysis module both adopt existing technologies, their functions are easy to implement for those skilled in the art, and therefore their principles and technical details are not repeated here.

[0043] The control module includes a PLC controller, several control buttons, and a display screen. The PLC controller is the control center of the utility model and is respectively connected to the emergency shut-off valve, flow control valve, mass flow meter, control pump, mixing pump P6, circulation pump, liquid level meter L, component analysis module, and real-time analysis module. Implementing the functions described herein is easy for those skilled in the art and does not require creative work. Therefore, the principles and technical details are not elaborated here.

[0044] Specifically, the workflow of this utility model is as follows:

[0045] 1. The component analysis module automatically analyzes the mass of the components in each component tank and transmits the analysis data back to the control module (PLC); the specific implementation is as follows:

[0046] (1) Turn on the automatic sampler and the circulation pump of a sampling circulation line. After circulating for 2 minutes (to ensure that the sample in the circulation line is the latest sample), open the corresponding sampling valve and take out the standard measured sample;

[0047] (2) The sample passes through a filter to remove water and impurities from the sample, and then enters a constant temperature box to stabilize the sample temperature at 13-18°C.

[0048] (3) The sample after temperature stabilization enters the automatic sample splitter, and the split sample is sent to the automatic sampler of the corresponding instrument;

[0049] (4) Start the automatic distillation range analyzer, nitrogen analyzer, sulfur analyzer, gas chromatograph, octane number analyzer and other instruments;

[0050] (5) The analyzed indicators are uploaded to the control module (PLC) via remote transmission.

[0051] (6) Repeat the above steps to complete the preliminary analysis of different components.

[0052] 2. The operator sets the label, standard and amount of finished oil to be blended in the control module (PLC);

[0053] 3. The control module (PLC) automatically calculates the amount of each component according to the finished oil standard;

[0054] 4. The control module opens the corresponding flow regulating valve and starts the control pump;

[0055] 5. The mass flow meter starts to calculate the component flow rate. When the mass reaches the calculated value, the corresponding control pump is turned off;

[0056] 6. The components are mixed in static mixer 1 M1 and mixer 2 M2, then mixed in mixer 3 M3, and then enter blending tank A;

[0057] 7. When all components have been output, start the mixing pump P6 of the blending tank A to start the circulation mode of the blended oil, start the circulation component analysis module simultaneously, and transmit the analysis data of the blending tank A back to the control module (PLC);

[0058] 8. The control module (PLC) compares the returned data with the standard value of the finished oil. When the analysis data stabilizes, the control module (PLC) immediately makes a judgment. If the analysis data is the same as the standard value, the oil blending is stopped to meet the sales standard; if the analysis data is inconsistent with the standard, the required amount of each component is recalculated and blending is continued until the standard is met.

[0059] 9. Blending tank A is equipped with a liquid level interlock. When the liquid level in blending tank A continues to rise and reaches the warning level, the interlock will be activated and all emergency shut-off valves will be closed to protect blending tank A.

[0060] 10. Blending tank A is equipped with an oil and gas recovery valve. When the oil and gas in blending tank A reaches a certain pressure, the oil and gas recovery valve opens and the oil and gas enter the oil and gas recovery system to protect the environment.

[0061] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
