Description

Technical Field

[0001] The present disclosure generally relates to the field of petroleum technology. More specifically, the present disclosure relates to a condensation-membrane separation oil and gas recovery and processing system, method and related products. Background Art

[0002] Petroleum and its various products are mixtures of various hydrocarbons. In the process of loading, unloading, storage, and sales of oil products, there are inevitably oil and gas evaporation and leakage. The evaporated and leaked oil and gas are a mixture of hydrocarbons and air, which are precursors to chemical pollution and ozone generation. They not only pollute the atmospheric environment, but also cause waste of resources and pose safety hazards. Recycling oil and gas can reduce pollution to the atmosphere and achieve the purpose of protecting the environment.

[0003] When the underground oil tank of the gas station reaches a certain pressure, the oil and gas recovery and processing device is started to process the oil and gas, convert the oil and gas in the oil tank into gasoline and flow back into the oil tank, and discharge the treated oil and gas that meet the standard requirements through the exhaust pipe. Specifically, the process methods for oil and gas recovery can include adsorption, absorption, and condensation. When the adsorption method is used, the mixed oil and gas enter the adsorption tank, where the oil and gas components are adsorbed on the surface by the adsorbent (generally activated carbon), while the air can be directly discharged because of its low adsorption force on the adsorbent. When the adsorbent reaches a certain adsorption amount and is saturated, the adsorption tank will switch to the desorption stage, and release the oil and gas previously adsorbed by the adsorbent by vacuum decompression and desorption, and suck it into the oil tank with a vacuum pump or liquefy it by other methods for recovery. However, the activated carbon adsorption of the aforementioned adsorption method will be saturated, need to be replaced regularly, and have high maintenance costs, and the activated carbon after adsorption needs to be treated as hazardous waste, which may cause secondary pollution. When the absorption method is used, the recovery rate of the absorption method is usually low, generally only about 80%, and cannot reach higher recovery standards. When using the condensation method, due to the high energy consumption of low-temperature refrigeration, for high-concentration oil and gas, the condensation equipment may need to be larger in scale, resulting in higher manufacturing costs. In addition, when the oil and gas condensation temperature is lower than 0°C, frost will form and regular defrosting is required.

[0004] In view of this, it is urgent to provide a condensation-membrane separation oil and gas recovery and processing system, method and related product solutions, so that oil and gas can be recovered at room temperature, which can improve the efficiency of oil and gas recovery. In addition, the air cooling method disclosed in the present invention can avoid defrosting the condenser, which can reduce costs. Summary of the invention

It should also be further understood that the term "and / or" used in this disclosure and claims refers to any combination of one or more of the associated listed items and all possible combinations, including these combinations.

[0029] As used in this specification and claims, the term "if" may be interpreted as "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" may be interpreted as meaning "upon determination" or "in response to determining" or "upon detection of [described condition or event]" or "in response to detecting [described condition or event]," depending on the context.

[0030] The specific implementation of the present disclosure is described in detail below with reference to the accompanying drawings.

[0031] Figure 1 An exemplary framework diagram of a condensation-membrane separation oil and gas recovery and processing system of some embodiments of the present disclosure is shown, the system includes a first oil and gas tank and a second oil and gas tank, the oil and gas include mixed oil and gas, and the system also includes: a boosting component 10, a condensing component 20 and a separating component 30; wherein the boosting component 10 is connected to the first oil and gas tank, and is used to boost the mixed oil and gas to obtain a first gas, wherein the temperature of the first gas is greater than the temperature of the mixed oil and gas; the condensing component 20 is connected to the boosting component 10, and is used to liquefy at least part of the gaseous petroleum in the first gas into a first liquid to obtain a first liquid and a second gas, wherein the second gas includes gaseous petroleum and gaseous air; and the separating component 30 is connected to the first output end of the condensing component 20, and is used to separate the second gas to obtain a third gas and a fourth gas, wherein the third gas includes gaseous petroleum, and the fourth gas includes gaseous air.

[0032] In some embodiments, the condensation component 20 includes an air cooling device to prevent the condensation component 20 from frosting.

[0033] In some embodiments, the aforementioned oil and gas tanks may include above-ground oil tanks and buried oil tanks. The aforementioned above-ground oil tanks may be located above the ground, and their structures are completely exposed to the external environment. The aforementioned above-ground oil tanks are easy to install, maintain and inspect. For example, maintenance personnel can directly operate and repair the external equipment of the oil tank (such as valves, liquid level gauges, etc.) without the need for complex operations such as excavation like buried oil tanks. The aforementioned buried oil tanks can be installed below the ground, and they have stable fire and explosion-proof capabilities, reducing the safety distance between the oil storage tanks and between them and adjacent buildings, saving land resources, and reducing the total cost of the project.

[0034] Preferably, the aforementioned first oil and gas tank and the aforementioned second oil and gas tank can be buried oil tanks, and the aforementioned buried oil tanks can be buried by soil, which is equivalent to providing a natural fire barrier for the oil tanks. When a fire occurs, it is difficult for the flames on the ground to directly touch the tank body of the oil tank, and the soil can effectively block the heat transfer and prevent the oil in the oil tank from exploding due to a sudden rise in temperature. Furthermore, its underground location makes it less disturbed by external fire sources. Static sparks generated during vehicle driving, sparks generated by accidental collisions, etc., are difficult to directly act on the buried oil tanks, thereby reducing the possibility of fire and explosion of the oil tanks caused by external fire sources. Finally, if the oil tank leaks, the soil can adsorb and limit the diffusion of the leaked oil. On the one hand, it can prevent the oil from volatilizing in large quantities to form a combustible mixture and avoid the risk of explosion; on the other hand, it can also reduce the harm of large-scale pollution caused by oil leakage to the surrounding environment.

[0035] In some embodiments, the buried oil tank may include a high-grade buried oil tank and a low-grade buried oil tank. The first oil and gas tank may include a high-grade oil and gas tank, and the second oil and gas tank may include a low-grade oil and gas tank. It is understood that the high-grade buried oil tank may store high-grade gasoline (such as No. 98 gasoline), and the low-grade oil and gas tank may store low-grade gasoline (such as No. 92 gasoline). It should be understood that, due to the relatively low octane number of low-grade oil and gas, when the oil and gas in the low-grade buried oil tank are recovered into the high-grade buried oil tank, the mixed oil and gas grade may be reduced, which cannot meet the use of engines that require high-grade oil and gas. In addition, the low-grade oil and gas may contain more impurities or components that affect the quality of high-grade oil and gas (such as sulfur content). When the oil and gas in the low-grade buried oil tank are recovered into the high-grade buried oil tank, the impurities in the low-grade buried oil tank may flow into the high-grade buried oil tank. Furthermore, recovering oil and gas from low-grade buried oil tanks into high-grade buried oil tanks may also affect key quality indicators such as the anti-knock performance of the high-grade gasoline.

[0036] In some embodiments, since the quality requirements of low-grade petroleum itself are relatively less stringent than those of high-grade petroleum, when the oil and gas in the high-grade buried oil tank are recovered into the low-grade buried oil tank, as long as the recovered oil and gas are properly treated to remove impurities that may affect the quality (such as moisture, colloid, etc.), the impact on the quality of the low-grade gasoline can be relatively small. It can be understood that the aforementioned first oil and gas tank can be a high-grade buried oil tank, and the aforementioned second oil and gas tank can be a low-grade oil and gas tank.

[0037] In some embodiments, the aforementioned boosting component 10 can be connected to the aforementioned first oil and gas tank. The aforementioned boosting component 10 may include a compressor, a boosting pump, an ejector, etc. Preferably, a boosting pump can be selected, which can accurately increase the gas pressure to the required level and also has high safety. Specifically, the aforementioned boosting pump can be an adjustable variable frequency boosting pump, which can adjust the frequency of compression, so that the efficiency of compression can be adjusted to adapt to gas stations with different sales, while extending the service life of the equipment. Furthermore, by adjusting the parameters of the boosting pump (such as driving pressure, flow, etc.), the gas pressure can be arbitrarily controlled within a very narrow range. In addition, the boosting pump operates stably under normal working conditions. It ensures the stability of the gas boosting process through a precise mechanical structure and control system, and the aforementioned boosting pump can safely and reliably boost the oil and gas.

[0038] In some embodiments, the boosting component may select a multi-stage boosting device, that is, select multiple boosting pumps connected in series, which can safely and efficiently boost the gas while reducing energy loss and equipment wear during a single-stage boosting process.

[0039] It is understandable that by using a boosting component to boost the mixed oil and gas, the pressure and temperature of the mixed oil and gas can be increased, and the aforementioned mixed oil and gas can have a higher heat content, which can be used in the subsequent condensation process. Specifically, a large amount of heat needs to be released when cooling the mixed oil and gas to a liquid state. If the mixed oil and gas is pressurized and heated before entering the condensation equipment, the heat it carries can be used as part of the energy source in the pre-cooling stage, which can reduce the energy consumption of the external refrigeration equipment. Furthermore, a larger temperature gradient is formed between the pressurized and heated oil and gas and the condensation equipment, and a larger temperature gradient can speed up the heat transfer. In the condensation process of the oil and gas from gas to liquid, this rapid heat transfer is conducive to improving the condensation efficiency, liquefying the oil and gas faster, and thus achieving efficient recovery.

[0040] In some embodiments, the aforementioned mixed oil and gas may include impurities, gaseous air, gaseous petroleum and petroleum in the form of mist droplets, and the aforementioned impurities may include rust, powder or dust in the pipeline, etc. Before pressurizing the aforementioned mixed oil and gas, the aforementioned mixed oil and gas may be filtered using a filtering component to obtain gaseous air, gaseous petroleum and petroleum in the form of mist droplets. In some embodiments, the aforementioned filtering component may include a filter, and the aforementioned filter may include a mechanical filter, an activated carbon filter or a ceramic filter, etc. After filtering the aforementioned mixed oil and gas, the aforementioned pressurizing component may be used to pressurize the aforementioned mixed gas, thereby obtaining a first gas, wherein the aforementioned first gas may include gaseous air and gaseous petroleum. It is understandable that the aforementioned first gas, due to the pressurization process, may have a temperature greater than the aforementioned mixed oil and gas, which may facilitate the subsequent condensation component to condense the aforementioned first gas.

[0041] In some embodiments, the aforementioned condensing component may include a cooling condensing device and an air-cooled condensing device. In some embodiments, the aforementioned cooling condensing device may realize the condensation of the gas by cooling, and the aforementioned air-cooled condensing device may reduce the temperature of the oil and gas by allowing the air to flow away the heat of the oil and gas through the temperature difference between the air and the aforementioned oil and gas, thereby reducing the temperature of the oil and gas. Specifically, the aforementioned cooling condensing device may include a shell and tube condenser, a plate condenser, a spiral plate condenser, and an immersion condenser, etc.; the aforementioned air-cooled device may include an air-cooled condenser and an air cooler. Preferably, an air-cooled condensing device may be selected, which has lower energy consumption than the cooling condensing device, and can also avoid defrosting the condenser, thereby reducing costs. In addition, since there is no contact between water and oil and gas, the air-cooled device does not have safety hazards such as short circuit and corrosion of electrical equipment caused by cooling water leakage, and can improve the safety of the entire oil and gas recovery system.

[0042] In some embodiments, after the first gas passes through the condensation component 20, the petroleum in the mist droplet state in the first gas can be completely converted into liquid petroleum, the gaseous petroleum can be at least partially converted into liquid petroleum, and the liquid petroleum can be the first liquid. The remaining gaseous petroleum and gaseous air in the first gas can continue to remain in the gaseous state and can form the second gas.

[0043] In some embodiments, the aforementioned separation component 30 may include a separation membrane group, the aforementioned separation membrane group may include a shell, the aforementioned shell may be set to a cylindrical shape, the aforementioned shell may be made of stainless steel, which is oil-resistant, ethanol-resistant and stable in nature, suitable for various types of automotive unleaded gasoline and ethanol gasoline, and can ensure service life.

[0044] In some embodiments, the separation membrane group may further include a center tube, which may be disposed in the middle of the shell. It is understood that the axis of the center tube may coincide with the axis of the shell. In some embodiments, a first cavity may be formed between the center tube and the shell, the interior of the first cavity may be filled with a membrane core, and a plurality of fine through holes may be disposed on the side of the center tube facing the membrane core, which may be used for the passage of petroleum gas. It is understood that the membrane core may be a polymer material, which has excellent selectivity and sensitivity and can accurately separate hydrocarbon components in an oil-gas mixture. Driven by a certain pressure, the oil-gas mixture can pass through the polymer membrane, while the air is blocked and discharged. When the oil-gas mixture passes through the polymer membrane, the hydrocarbon components in the oil and gas can quickly penetrate through, while the air components are blocked and discharged.

[0045] In some embodiments, the side of the shell may also be provided with an air inlet and an air outlet connected to the first cavity. The second gas may enter the first cavity from the air inlet, and in the first cavity, the second gas flows along the membrane core. In this process, the oil in the first gas can pass through the membrane core, flow to the side of the central tube, and then flow into the central tube through the through holes on the central tube, while the air in the second gas cannot pass through the membrane core, and thus can be discharged by the air outlet.

[0046] In some embodiments, the aforementioned separation membrane group may be provided in plurality, and the aforementioned plurality of separation membrane groups may be connected in series or in parallel.

[0047] In some embodiments, after the second gas passes through the separation component 30, the third gas in the second gas can be output from the output end of the central tube, and the fourth gas in the second gas can be output from the gas outlet end of the shell, so that the third gas and the fourth gas can be separated. In some embodiments, the third gas shell includes gaseous petroleum, and the fourth gas can include gaseous air.

[0048] Through the aforementioned mixed oil and gas condensation recovery system, oil and gas recovery can be carried out at room temperature, which can improve the efficiency of oil and gas recovery. In addition, by using air cooling, defrosting of the condenser can be avoided, thereby reducing costs.

[0049] Figure 2 An exemplary framework diagram of a condensation-membrane separation oil and gas recovery processing system according to some other embodiments of the present disclosure is shown. Figure 2 As shown, the mixed oil and gas condensation recovery system may include a first oil and gas tank, a second oil and gas tank, a pressurizing component 10 , a condensing component 20 and a separating component 30 .

[0050] In some embodiments, the system further includes a pretreatment component 40, one end of which is connected to the first oil and gas tank, and the other end of which is connected to the boosting component 10, for performing filtering operations before boosting the mixed oil and gas.

[0051] In some embodiments, the pre-treatment component 40 may include a filter component, and the filter component may include an input end and an output end. The input end of the filter component may be connected to the first oil and gas tank, and the output end of the pre-filter component may be connected to the input end of the boost component. In some embodiments, the filter component may include a filter, and the filter may include a mechanical filter, an activated carbon filter, or a ceramic filter, etc., which can filter out impurities such as rust, powder, or dust in the mixed oil and gas.

[0052] In some embodiments, a pressure sensor may be provided between the filter component and the first oil and gas tank to detect the pressure in the pipeline. It is understood that when the boost component boosts the mixed oil and gas, the pressure inside the pipeline will also increase. When the pressure in the pipeline is greater than the preset pressure, the boost component may stop boosting the mixed oil and gas to ensure the safety of the mixed oil and gas condensation recovery system.

[0053] By setting the above-mentioned pretreatment components, impurities can be prevented from entering the condensation components and separation components, thereby extending the service life of the equipment and reducing the frequency of equipment maintenance and replacement. Furthermore, it can also ensure that the recovered oil and gas have a high purity and meet the quality requirements for further processing or reuse.

[0054] In some embodiments, the system further includes a first recovery component 50 , which is located between the condensation component 20 and the separation component 30 and is used to recover the first liquid in the condensation component 20 .

[0055] In some embodiments, after the condensation component 20 condenses the first gas, a first liquid and a second gas can be obtained, wherein the first liquid can include liquid petroleum, and the second gas can include gaseous petroleum and gaseous air.

[0056] In some embodiments, the first recovery component 50 may include a liquid collector, which may include a liquid collector body, a first inlet, a first exhaust port, and a first drain port. The first inlet may be connected to the output end of the condensation component 20, and the first liquid and the second gas may enter the liquid collector body from the output end of the condensation component 20 through the first inlet. In some embodiments, a one-way valve may be provided between the condensation component 20 and the liquid collector to prevent the second gas in the liquid collector body from flowing to the condensation component 20, thereby avoiding interference with the normal operation of the condensation component and thus avoiding reduction in the condensation efficiency of the condensation component.

[0057] In some embodiments, the first exhaust port may be connected to the input end of the separation component 30 , and the second gas may enter the separation component 30 through the first exhaust port.

[0058] In some embodiments, a second condensation component may be provided between the first recovery component 50 and the separation component 30, and the second condensation component may include a heat exchanger, a gas-liquid separator and a pressure sensor. The pressure sensor may be used to detect the pressure of the pipeline. In some embodiments, the heat exchanger may include a plate heat exchanger, and the plate heat exchanger may further gasify a small amount of residual atomized oil gas by the second gas, and the gas-liquid separator may be an oleophobic and hydrophobic gas-liquid separator to separate gas and liquid, thereby preventing the residual atomized oil gas from entering the separation component and affecting the separation effect of the separation component.

[0059] In some embodiments, the first liquid discharge port can be connected to the second oil and gas tank, and the first liquid in the liquid collector body can be transferred to the second oil and gas tank, so as to realize the recovery of oil. In some embodiments, a solenoid valve can be provided on the pipeline between the first liquid discharge port and the second oil and gas tank.

[0060] By setting the aforementioned first recovery part, the aforementioned first liquid can be recovered into the oil and gas tank, which can increase the efficiency of oil and gas recovery.

[0061] In some embodiments, the system further comprises a second recovery component 60, which is connected to the separation component 30 and is used to recover the third gas, so as to recover the oil in the mixed oil and gas. In some embodiments, the second recovery component 60 comprises a vacuum pump, one end of which is connected to the second oil and gas tank, and the other end of which is connected to the separation component 30, so as to provide negative pressure to the separation component 30, so as to recover the third gas.

[0062] In some embodiments, after the separation component 30 separates the second gas, a third gas and a fourth gas can be obtained, wherein the third gas can include gaseous petroleum, and the fourth gas can include gaseous air. The output end of the central pipe of the separation component 30 can be connected to the second recovery component 60, and the third gas can be recovered into the second oil and gas tank through the second recovery component 60.

[0063] In some embodiments, the second recovery component 60 may include a vacuum pump, one end of which may be connected to the central tube, and the other end of which may be connected to the second oil and gas tank. The vacuum pump may be a rotary vane vacuum pump, which may form a pressure difference between the inner low and the outer high in the separation membrane group in the separation component 30 during operation, which is conducive to the separation membrane group to penetrate high-concentration oil and gas and pump it back to the buried oil tank. Specifically, the vacuum pump may provide a negative pressure environment for the central tube of the separation membrane group, and the pressurizing component may pressurize the first gas, so that the second gas may have a higher pressure. It is understandable that when the second gas flows into the separation component 30, the interior of the second gas and the interior of the central tube may have a large pressure difference, which may increase the efficiency of the separation component in separating the third gas and the fourth gas. Further, the vacuum pump may recycle the third gas into the second oil and gas tank, thereby realizing the recovery of oil and gas.

[0064] By setting up the aforementioned second recovery unit, the aforementioned mixed oil and gas can be subjected to multiple condensation treatments, so that more gaseous oil in the first gas can be converted into liquid oil, which can improve the efficiency of oil and gas recovery.

[0065] Figure 3a The schematic diagram of the structure of the separation membrane group of some embodiments of the present disclosure is shown. Figure 3a As shown, in some embodiments, the separation component 30 includes one or more separation membrane groups, wherein the plurality of separation membrane groups are connected in parallel to improve the efficiency of recovering oil.

[0066] In some embodiments, the separation membrane group may include a housing 31, which may be cylindrical and made of stainless steel. Two end caps 32 may be provided at both ends of the housing 31, and a central tube 33 may be provided inside the housing 31.

[0067] In some embodiments, one end of the central tube 33 may be against one end cap 32, and the other end of the central tube 33 may pass through another end cap and extend out and be connected to the second recovery component. The side of the central tube 33 may be formed with a plurality of through holes for the passage of petroleum gas.

[0068] In some embodiments, the housing 31, the end cover 32 and the central tube 33 can directly form a first cavity 34, the interior of the first cavity can be filled with a membrane core 35, and the membrane core can be wound around the outside of the central tube 33. In some embodiments, the membrane core 35 can be a polymer material. Under normal pressure, oil and gas can permeate through the polymer material, while air cannot permeate through the polymer material.

[0069] In some embodiments, the separation membrane group may further include an air inlet pipe 36 and an air outlet pipe 37. The air inlet pipe 36 and the air outlet pipe 37 may be located near the end cap 32. It is understood that the air inlet pipe 36 and the air outlet pipe 37 may be located near the two sides of the same end cap, or may be located near two different end caps. It is understood that when the air inlet pipe 36 and the air outlet pipe 37 are located near different end caps, when the air inlet pipe 36 is located near the upper end cap, the air outlet pipe 37 may be located near the lower end cap; when the air inlet pipe 36 is located near the lower end cap, the air outlet pipe 37 may be located near the upper end cap.

[0070] The aforementioned air inlet pipe 36 can be close to the lower end cover, and the aforementioned air outlet pipe 37 can be close to the upper end cover. When the aforementioned first gas flows into the cavity from the aforementioned air inlet pipe 36, the aforementioned first gas will move from bottom to top along the cavity. When the first gas moves upward and contacts the membrane core 35, the petroleum gas in the first gas can penetrate the membrane core 35 and move toward the central tube 33, and finally can penetrate into the central tube 33. After the aforementioned petroleum gas penetrates into the central tube 33, it can continue to move upward along the central tube 33, and finally can flow out through the gas outlet end of the central tube. It can be understood that the aforementioned gaseous petroleum flowing out from the gas outlet end of the central tube can be the third gas. It can be understood that after the aforementioned second gas moves upward and contacts the membrane core 35, the air cannot penetrate the membrane core 35, and therefore cannot penetrate into the central tube. The aforementioned air can continue to move upward along the cavity, and finally can flow out from the gas outlet pipe 37. It can be understood that the gaseous petroleum flowing out from the gas outlet end of the central tube can be the third gas. It can be understood that after the aforementioned second gas moves upward and contacts the membrane core 35, the air cannot penetrate the membrane core 35, and therefore cannot penetrate into the central tube. The aforementioned air can continue to move upward along the cavity, and finally can flow out from the gas outlet pipe 37. It can be understood that the gas flowing out from the aforementioned gas outlet pipe 37 can be the fourth gas.

[0071] Figure 3b The schematic diagram of the structure of multiple separation membrane groups in parallel in some embodiments of the present disclosure is shown. Figure 3bAs shown, in some embodiments, the separation membrane group may include a first separation membrane group 301, a second separation membrane group 302 and a third separation membrane group 303. The first separation membrane group 301 may include a first separation air inlet pipe 3011, a first separation air outlet pipe 3012 and a first central pipe 3013. The second separation membrane group 302 may include a second separation air inlet pipe 3021, a second separation air outlet pipe 3022 and a second central pipe 3023. The third separation membrane group 303 may include a third separation air inlet pipe 3031, a third separation air outlet pipe 3032 and a third central pipe 3033. Specifically, the first separation air inlet pipe 3011 may be connected to the second separation air inlet pipe 3021 and the third separation air inlet pipe 3031, and the first separation air outlet pipe 3012 may be connected to the second separation air outlet pipe 3022 and the third separation air outlet pipe 3032. It is understandable that the first central pipeline 3013, the second central pipeline 3023 and the third central pipeline 3033 can also be connected together. Through the above arrangement, the first separation membrane group 301, the second separation membrane group 302 and the third separation membrane group 303 can be connected in parallel.

[0072] In some embodiments, after the second gas enters the separation membrane group 30, the first gas may flow into the first separation inlet pipe 3011, the second separation inlet pipe 3021 or the third separation inlet pipe 3031, and after being separated by the corresponding separation membrane group 30, the third gas may flow out from the corresponding first central pipe 3013, the second central pipe 3023 or the third central pipe 3033. The fourth gas may flow out from the corresponding first separation outlet pipe 3012, the second separation outlet pipe 3022 or the third separation outlet pipe 3032.

[0073] It is understandable that the gas is pressurized by the aforementioned booster pump so that the air inlet end of the separation membrane group has a relatively high pressure. Furthermore, the vacuum pump can provide negative pressure to the central tube of the separation membrane group, so that a relatively large pressure difference can be generated in the aforementioned separation membrane group, and the situation of insufficient pressure caused by parallel connection can be avoided. By designing multiple separation membrane groups in parallel, the second gas can be separated at the same time. The time for separating the second gas can be reduced, thereby improving the efficiency of oil and gas recovery.

[0074] Figure 3c A schematic diagram showing the structure of multiple separation membrane groups connected in series in some embodiments of the present disclosure is shown, such as Figure 3cAs shown, in some embodiments, the separation membrane group may include a fourth separation membrane group 304, a fifth separation membrane group 305, and a sixth separation membrane group 306. The fourth separation membrane group 304 may include a fourth separation air inlet pipe 3041, a fourth separation air outlet pipe 3042, and a fourth central pipe 3043. The fifth separation membrane group 305 may include a fifth separation air inlet pipe 3051, a fifth separation air outlet pipe 3052, and a fifth central pipe 3053. The sixth separation membrane group 306 may include a sixth separation air inlet pipe 3061, a sixth separation air outlet pipe 3062, and a sixth central pipe 3063. Specifically, the fourth separation air outlet pipe 3042 may be connected to the fifth separation air inlet pipe 3051, and the fifth separation air outlet pipe 3052 may be connected to the sixth separation air inlet pipe 3061, so that the fourth separation membrane group 304, the fifth separation membrane group 305, and the sixth separation membrane group 306 may be connected in series.

[0075] In some embodiments, after the first gas flows in from the fourth separation inlet pipe 3041, it can be separated by the fourth separation membrane group 304, and the second gas can flow out from the fourth central pipe 3043. The gas of the first gas that does not flow into the fourth central pipe 3043 can flow out from the fourth separation outlet pipe 3042 and flow into the fifth separation inlet pipe 3051, so that it can be filtered by the fifth separation membrane group 305. The second gas flowing out of the fifth central pipe 3053 can also be collected in the oil tank. The gas flowing out of the fifth separation outlet pipe 3052 can flow into the sixth separation inlet pipe 3061 again, and be separated by the sixth separation membrane group 306, so that the gaseous oil and the gaseous air can be further separated.

[0076] It can be understood that by connecting the aforementioned separation membrane groups in series, the contact area and contact time between the mixed oil and gas and the membrane core can be increased, and the gaseous oil and gaseous air in the mixed oil and gas can be separated multiple times, thereby increasing the oil recovery rate.

[0077] It should be understood that the aforementioned Figure 3a - Attachment Figure 3c The membrane core of the separation membrane group can be made of a polymer material that allows oil and gas to permeate but does not allow air to permeate, and the connection method of the above separation membrane group can also be set based on the above polymer material.

[0078] In some embodiments, a second separation membrane group can also be used, and the second membrane core of the aforementioned second separation membrane group can be set to a second polymer material that allows air to permeate but does not allow oil and gas to permeate. Specifically, the aforementioned second separation membrane group can include a second air inlet end, a second air outlet end, and a second central tube air outlet end. After the aforementioned second gas enters the separation membrane group from the second air inlet end, the gaseous air in the aforementioned second gas can penetrate the membrane core of the second separation membrane group, thereby flowing into the central tube of the second separation membrane group, and can be discharged from the second central tube air outlet end. The gaseous oil in the aforementioned second gas cannot penetrate the membrane core of the aforementioned second separation membrane group, thereby being separated from the aforementioned air and flowing out from the second air outlet end, and finally flowing into the second oil and gas tank.

[0079] Figure 4 A schematic diagram of a condensation-membrane separation oil and gas recovery and processing system according to some embodiments of the present disclosure is shown. Figure 4 As shown, the system may include an oil tank, a pretreatment component, a pressurization component, a condensation component, a first recovery component, a separation component and a second recovery component, and the aforementioned separation membrane group may be the first membrane group.

[0080] In some embodiments, the oil tank may include a low-grade buried oil tank 401 and a high-grade buried oil tank 402 , the pretreatment component may include a filter 403 , and the boosting component may include a boosting pump 404 .

[0081] In some embodiments, the input end of the filter 403 can be connected to the high-grade buried oil tank 402, and the mixed oil and gas can enter the filter 403 from the high-grade buried oil tank 402. Further, a pressure sensor 4021 can be provided between the filter 403 and the high-grade buried oil tank 402. In some embodiments, the output end of the filter 403 can be connected to the input end of the booster pump 404, and the filtered mixed gas can be transmitted to the booster pump 404.

[0082] In some embodiments, the aforementioned condensation component may include a condenser 405. The aforementioned condenser 405 input end may be connected to the aforementioned booster pump 404 output end, and further, a temperature sensor 4041 and a one-way valve 4042 may be provided between the aforementioned condenser 405 and the booster pump 404. The aforementioned temperature sensor 4041 may be used to detect the temperature in the pipeline. It is understood that the aforementioned booster pump 404 will generate a large amount of heat when boosting, thereby causing the temperature to rise. When the aforementioned temperature is greater than the preset temperature, the booster pump 404 or other components in the system may be damaged or exploded, wherein the aforementioned preset temperature may be less than the temperature corresponding to the explosion-proof grade temperature group. By setting the aforementioned temperature sensor 4041, when the temperature in the system is greater than the aforementioned preset temperature, the explosion-proof control box 410 may control the aforementioned system to shut down, thereby entering a standby state, and avoiding the booster pump 404 from malfunctioning due to excessive temperature.

[0083] In some embodiments, the first recovery component may include a liquid collector 406, the first inlet of the liquid collector 406 may be connected to the output end of the condenser 405, and the first liquid and the second gas condensed by the condenser 405 may enter the liquid collector 406 through the first inlet. The first liquid discharge port of the liquid collector 406 may be connected to the low-grade buried oil and gas tank 401, and the first liquid may be collected in the low-grade buried oil and gas tank 401. The first exhaust port of the liquid collector 406 may be used to transport the second gas.

[0084] In some embodiments, the separation component may include a plurality of separation membrane groups 407 connected in parallel. The separation membrane group 407 may include a separation membrane group air inlet end 4071, a separation membrane group output end 4072 and a central tube output end 4073. The separation membrane group air inlet end 4071 may be connected to the first exhaust port of the liquid collector 406. Further, a second condensation component may be provided between the separation membrane group 407 and the liquid collector 406, and the second condensation component may include a plate heat exchanger 4061, a gas-liquid separator 4062 and a pressure sensor 4063. In some embodiments, the plate heat exchanger 4061 may be used to perform secondary gasification on the second gas, so that the misted petroleum in the second gas may be partially converted into gaseous petroleum, thereby preventing a small amount of residual misted oil gas from entering the separation membrane group and affecting the separation effect. By providing the second condensation component, the recovery rate of gaseous petroleum may be increased during the oil and gas recovery process, thereby increasing the efficiency of oil and gas recovery.

[0085] In some embodiments, after the second gas flows into the separation membrane group 407 through the second condensation component, the separation membrane group 407 can separate the second gas, thereby obtaining a third gas and a fourth gas, wherein the third gas can include gaseous petroleum, and the fourth gas can include gaseous air. The central tube output end 4073 can be connected to the vacuum pump 409 of the second recovery component, and the third gas can be transmitted to the low-grade buried oil tank 401, thereby realizing the recovery of oil and gas.

[0086] In some embodiments, the separation membrane group output end 4072 can be connected to the exhaust pipe 408, and the fourth gas can be discharged from the exhaust pipe 408. Specifically, the exhaust pipe 408 can also be provided with a solenoid valve 4081, a regulating valve 4082, a concentration sensor 4083 and a flame arrester 4084 in sequence. It can be understood that the solenoid valve 4081 can control the on-off of the exhaust pipe 408, and the regulating valve 4082 can extract the air in the exhaust pipe 408 to reduce the pressure. The concentration sensor 414 can detect the concentration of the fourth gas in the exhaust pipe 408. The flame arrester 4084 can play a role in isolating smoke and preventing fire, thereby preventing smoke and flames from spreading through the pipeline, and then preventing smoke or flames from flowing into the oil tank, which may cause an explosion.

[0087] In some embodiments, a connecting component 412 may be provided between the aforementioned high-grade buried oil tank 401 and the low-grade buried oil tank 402 to balance the pressure difference between the aforementioned high-grade buried oil tank 401 and the low-grade buried oil tank 402.

[0088] In some embodiments, the aforementioned system may also include an explosion-proof control box 410 and a human-computer interaction console 411, wherein the aforementioned explosion-proof control box 410 may be provided with a control and monitoring system, which may operate and monitor the equipment in the oil and gas recovery system, including leak detection, pressure control, overheat protection, etc., to ensure the safe operation of the system under normal and abnormal conditions. The aforementioned system may also include a PLC control module and a data acquisition device, and the PLC control module may include a remote control module, which may control the start and stop of the vacuum pump and the exhaust pump, and the switch of the solenoid valve.

In addition, the oil and gas recovery and processing device is also equipped with a wireless remote module, which can realize the remote control function of the on-site equipment through remote operation, and can realize remote parameter modification, fault diagnosis and partial fault repair, program upgrade and other advanced remote maintenance functions.

[0090] Figure 5 A method 500 for a condensation-membrane separation oil and gas recovery processing system according to some embodiments of the present disclosure is shown. Figure 5 As shown, the oil and gas tank includes a first oil and gas tank and a second oil and gas tank, the mixed oil and gas condensation recovery system includes a boosting component connected to the first oil and gas tank, a condensing component connected to the boosting component and a separation component connected to the condensing component, and the method includes: S510 using the boosting component to perform a boosting operation on the oil and gas, for boosting the mixed oil and gas to obtain a first gas; S520 using the condensing component to perform a condensing operation on the first gas to obtain a first liquid and a second gas; S530 using the separation component to separate the second gas to obtain a third gas and a fourth gas, wherein the third gas includes gaseous petroleum and the fourth gas includes gaseous air.

[0091] In some embodiments, the use of a pressurizing component to pressurize the mixed oil and gas may include pre-treating the mixed oil and gas and pressurizing the mixed oil and gas. Specifically, the mixed oil and gas may include impurities, gaseous air, gaseous petroleum, and petroleum in a mist droplet state. The mixed oil and gas may be filtered through a filter, so that the impurities can be filtered, and the impurities can be prevented from entering the equipment of the condensation component, thereby extending the service life of the equipment and reducing the frequency of equipment maintenance and replacement. Pressurizing the mixed oil and gas may include using a pressurizing component to pressurize the mixed oil and gas, which may increase the temperature and pressure in the mixed oil and gas, and provide a high temperature reference for the subsequent condensation operation, thereby improving the efficiency of condensation. It is understandable that the first gas may include gaseous air, gaseous petroleum, and petroleum in a mist droplet state.

[0092] In some embodiments, the first gas may be condensed using a condensation component, so that the gaseous petroleum in the first gas may be at least partially converted into liquid petroleum. It is understood that the aforementioned condensation component may include the use of an air-cooled condenser, which may avoid the need to defrost the condenser due to low temperature. By recovering the aforementioned liquid petroleum, the efficiency of petroleum recovery may be improved. In some embodiments, the second gas may be separated using a separation component to obtain a third gas and a fourth gas, which may include using a separation membrane group to separate the gaseous petroleum and gaseous air in the second gas. It is understood that the membrane core in the aforementioned separation membrane group may be a polymer material that allows gaseous petroleum to permeate but does not allow air to permeate. After the aforementioned second gas flows through the aforementioned membrane core, it can be separated into gaseous petroleum and gaseous air, thereby obtaining a third gas and a fourth gas.

[0093] In some embodiments, a vacuum pump can be used to recover the third gas. It is understood that the vacuum pump generates suction force formed by pressure difference on the output end of the separation membrane group, so that the second gas can be sucked into the oil tank to recover oil from the mixed oil and gas.

[0094] Through the above method, oil and gas recovery can be achieved at room temperature, which can improve the efficiency of oil and gas recovery. In addition, by using air cooling, defrosting of the condenser can be avoided, thereby reducing costs.
