A facility that can effectively absorb oil and gas.

Abstract

This utility model relates to the field of oil and gas treatment technology, and specifically discloses a facility that can effectively absorb oil and gas. A wire mesh demister is installed inside the diesel washing tower, and a distributor is installed at one end of the tower near the demister. A diesel feed flange is installed on one side of the tower, and an oil and gas feed flange is installed on the outer surface away from the diesel feed flange. The diesel feed flange on the tower surface is used for diesel fuel feeding, while the oil and gas enter the tower through the oil and gas feed flange. The diesel fuel circulates from top to bottom within the tower, counter-currently contacting the oil and gas flowing upwards. This allows the oil and gas to dissolve in the diesel fuel. The counter-current flow maintains a large concentration difference between the gas and liquid phases within the tower, thus more effectively promoting the dissolution of organic components in the oil and gas into the diesel fuel. The diesel washing tower effectively absorbs oil and gas, avoiding oil waste, reducing the emission of toxic and harmful substances, and protecting the environment.

Description

Technical Field

[0001] This utility model relates to the field of oil and gas treatment technology, and in particular to a facility that can effectively absorb oil and gas. Background Technology

[0002] In numerous locations involving oil storage and transportation, such as petrochemical plants, gas stations, and oil depots, the generation of oil and gas is a common phenomenon. Oil is volatile, and during loading and unloading, tank breathing, and storage, large amounts of oil and gas evaporate into the air. This oil and gas not only contains various volatile organic compounds, which are important precursors to photochemical smog and cause serious atmospheric pollution, but it is also flammable and explosive, posing significant safety hazards. Therefore, developing a facility that can effectively absorb oil and gas is of paramount importance for both environmental protection and safe production. Currently, the following technologies are commonly used in the field of oil and gas absorption to treat oil and gas:

[0003] 1. Absorption Technology: This method uses specific absorbents, such as diesel oil or kerosene, organic solvents. Through gas-liquid contact, the organic components in the oil and gas dissolve in the absorbent, achieving the purpose of absorbing the oil and gas. However, this method requires the selection of a suitable absorbent to ensure absorption efficiency and selectivity. Furthermore, it necessitates subsequent treatment of the enriched solution after absorption, increasing processing costs.

[0004] 2. Condensation Technology: Based on the differences in boiling points among the components in oil and gas, this technology condenses some of the components into liquid by lowering the temperature, thereby achieving oil and gas recovery. This technology is suitable for the recovery of high-concentration, high-boiling-point oil and gas, but it is not effective for recovering low-boiling-point components. Furthermore, it has high equipment investment and operating costs and requires a large amount of cooling energy.

[0005] Currently, various types of oil and gas absorption facilities exist on the market. Some small gas stations use simple activated carbon adsorption devices, which are relatively simple in structure and low in cost, but have limited processing efficiency and require frequent replacement of activated carbon, resulting in high maintenance costs. Some oil depots use facilities with a condensation-adsorption combined process, which can improve oil and gas recovery efficiency, but the equipment occupies a large area and has high investment costs, making it less suitable for places with limited space or tight budgets. Some enterprises also use absorption-distillation combined units, which treat oil and gas more thoroughly, but the process is complex, difficult to operate, and requires a high level of technical expertise from operators.

[0006] However, there is a prominent problem with these existing oil and gas absorption facilities: some existing absorption facilities, such as the simple activated carbon adsorption devices used in some small gas stations, have limited processing efficiency and relatively small activated carbon adsorption capacity. For high-concentration or high-flow-rate oil and gas, it is difficult to achieve efficient adsorption in a short time, resulting in some oil and gas being emitted into the atmosphere without sufficient treatment. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a facility that can effectively absorb oil and gas, solving the technical problem that some existing absorption facilities, such as the simple activated carbon adsorption devices used in some small gas stations, have limited processing efficiency and relatively small activated carbon adsorption capacity. For high-concentration or high-flow-rate oil and gas, it is difficult to achieve efficient adsorption in a short time, resulting in some oil and gas being emitted into the atmosphere without sufficient treatment.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A facility capable of effectively absorbing oil and gas includes a diesel washing tower, wherein a wire mesh demister is installed inside the diesel washing tower, the wire mesh demister having a nominal diameter of 600 mm, and a distributor is installed inside the diesel washing tower near one end of the wire mesh demister, the distributor having a flow rate of twelve cubic meters per hour.

[0010] Preferably, a diesel feed flange is provided on one side of the diesel washing tower, and an oil and gas feed flange is provided on the outer surface of the diesel washing tower away from the diesel feed flange.

[0011] Preferably, a circulating pump is installed on the outer surface of the diesel washing tower.

[0012] Preferably, an oil pump is installed at the end of the outer surface of the diesel washing tower away from the circulation pump, and both the circulation pump and the oil pump are centrifugal pumps.

[0013] Preferably, the upper end of the diesel washing tower is equipped with an oil and gas recovery flange.

[0014] Preferably, a magnetic level gauge is fixedly connected to the outer surface of the diesel washing tower.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The diesel feed flange installed on the surface of the diesel washing tower is used for diesel fuel feeding. The oil and gas enter the interior of the diesel washing tower through the oil and gas feed flange. Through the diesel washing tower, the diesel fuel circulates from top to bottom within the equipment, coming into countercurrent contact with the oil and gas flowing from bottom to top. This allows the oil and gas to dissolve in the diesel fuel. The countercurrent flow ensures that the gas and liquid phases maintain a large concentration difference within the tower, thereby more effectively promoting the dissolution of organic components in the oil and gas into the diesel fuel. The diesel washing tower effectively absorbs oil and gas, avoiding oil waste, reducing the emission of toxic and harmful substances, protecting the environment, reducing harm to human health, eliminating safety hazards caused by oil and gas, and ensuring public safety.

[0017] II. Distributors are used to ensure that the liquid is evenly distributed across the cross-section of the tower, thereby ensuring high-efficiency operation. Wire mesh demisters are used to separate mist from the gas to improve operating conditions, optimize process parameters, reduce equipment corrosion, extend equipment service life, increase throughput and recover valuable materials, protect the environment and reduce air pollution.

[0024] This application provides a facility that effectively absorbs oil and gas, effectively solving the problems of some existing absorption facilities, such as the simple activated carbon adsorption devices used in some small gas stations. These devices have limited processing efficiency and relatively small activated carbon adsorption capacity, making it difficult to achieve efficient adsorption of high-concentration or high-flow-rate oil and gas in a short time. This results in some oil and gas being emitted into the atmosphere without sufficient treatment. The diesel feed flange installed on the surface of the diesel washing tower is used for diesel feed, and the oil and gas enter the interior of the diesel washing tower through the oil and gas feed flange. Through the diesel washing tower, the diesel circulates from top to bottom in the equipment, making counter-current contact with the oil and gas flowing from bottom to top. This allows the oil and gas to dissolve in the diesel. The counter-current flow can maintain a large concentration difference between the gas and liquid phases in the tower, thereby more effectively promoting the dissolution of organic components in the oil and gas into the diesel. By effectively absorbing oil and gas through the diesel washing tower, oil waste is avoided, emissions of toxic and harmful substances are reduced, the environment is protected, harm to human health is reduced, safety hazards caused by oil and gas are eliminated, and public safety is ensured.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that some existing absorption facilities, such as the simple activated carbon adsorption devices used in some small gas stations, have limited processing efficiency and relatively small activated carbon adsorption capacity. For high-concentration or high-flow-rate oil and gas, it is difficult to achieve efficient adsorption in a short time, resulting in some oil and gas being emitted into the atmosphere without sufficient treatment. The overall idea is as follows: A facility that can effectively absorb oil and gas includes a diesel washing tower 11. The diesel washing tower 11 is equipped with a wire mesh demister 12 with a nominal diameter of 600 mm. A distributor 13 is provided at one end of the diesel washing tower 11 near the wire mesh demister 12. The distributor 13 has a flow rate of twelve cubic meters per hour. The distributor 13 is used to make the liquid evenly distributed on the cross-section of the tower, thereby ensuring high-efficiency operation. The wire mesh demister 12 is used to separate mist in the gas to improve operating conditions, optimize process indicators, reduce equipment corrosion, extend equipment service life, increase processing capacity and recover valuable materials, protect the environment, and reduce air pollution.

[0027] A diesel feed flange 14 is installed on one side of the diesel washing tower 11. An oil and gas feed flange 15 is installed on the outer surface of the diesel washing tower 11 away from the diesel feed flange 14. A circulation pump 16 is installed on the outer surface of the diesel washing tower 11, and an oil pump 17 is installed at the end of the outer surface of the diesel washing tower 11 away from the circulation pump 16. Both the circulation pump 16 and the oil pump 17 are centrifugal pumps. An oil and gas recovery flange 18 is installed at the upper end of the diesel washing tower 11. The diesel washing tower 11 is connected to the circulation pump 16 and the oil pump 17 via pipelines. The flow rates of both the circulation pump 16 and the oil pump 17 are 12 cubic meters per hour. The other end of the oil pump 17 is connected to an oil storage tank via a pipeline. The diesel feed flange 14 installed on the surface of the diesel washing tower 11 is used for diesel feed, while oil and gas are fed via the oil and gas feed. Flange 15 enters the diesel washing tower 11, through which diesel fuel circulates from top to bottom within the equipment, coming into counter-current contact with the rising oil and gas. This causes the oil and gas to dissolve in the diesel fuel, which then flows downwards to the bottom of the diesel washing tower 11. The diesel fuel that has lost its adsorption effect is periodically transported back to the oil tank by the oil pump 17. The diesel washing tower 11 effectively absorbs oil and gas, avoiding oil waste, reducing the emission of toxic and harmful substances, protecting the environment, reducing harm to human health, eliminating safety hazards caused by oil and gas, and ensuring public safety. The diesel washing tower 11 is connected to the oil and gas recovery equipment via the oil and gas recovery flange 18, achieving a closed-loop circulation. A small amount of unabsorbed oil and gas enters the oil and gas recovery system through the oil and gas recovery flange 18 for treatment.

[0028] A magnetic level gauge 19 is fixedly connected to the outer surface of the diesel washing tower 11. The circulation pump 16 is used to circulate diesel fuel from top to bottom in the equipment, making counter-current contact with the oil and gas from bottom to top. The oil pump 17 is used to transport diesel fuel that has lost its adsorption effect back to the oil storage tank. The magnetic level gauge 19 is used to observe the diesel fuel level in the equipment. By equipping the equipment with the magnetic level gauge 19, the function of monitoring the liquid level by on-site personnel is realized.

[0029] To address the problems existing in the prior art, this utility model provides a facility that can effectively absorb oil and gas. A diesel feed flange 14 installed on the surface of the diesel washing tower 11 is used for diesel fuel feeding, while oil and gas enter the interior of the diesel washing tower 11 through an oil and gas feed flange 15. The diesel fuel circulates from top to bottom within the equipment through the diesel washing tower 11, coming into counter-current contact with the oil and gas flowing upwards. This allows the oil and gas to dissolve in the diesel fuel. The counter-current flow maintains a large concentration difference between the gas and liquid phases within the tower, thus more effectively promoting the dissolution of organic components in the oil and gas into the diesel fuel. The effective absorption of oil and gas by the diesel washing tower 11 avoids oil waste, reduces the emission of toxic and harmful substances, protects the environment, reduces harm to human health, eliminates safety hazards caused by oil and gas, and ensures public safety.

[0030] Diesel Washing Tower 11: As the core processing equipment, it provides space for the contact reaction between diesel and oil and gas;

[0031] Wire mesh demister 12: Nominal diameter 600mm, installed inside the diesel washing tower 11; its function is to separate mist from gas, which can effectively improve operating conditions and optimize process parameters; it can reduce the impact and corrosion of mist on the internal structure of the equipment, and extend the service life of equipment such as the diesel washing tower 11; at the same time, by separating mist, valuable materials can be recovered, increasing the throughput and reducing the pollution of the atmosphere by mist emissions;

[0032] Distributor 13: with a flow rate of 12 cubic meters per hour, located inside the diesel washing tower 11 near one end of the wire mesh demister 12; its main function is to make the liquid entering the diesel washing tower 11 evenly distributed on the cross-section of the tower; the evenly distributed liquid can make more full contact with the oil and gas from bottom to top, ensuring high-efficiency operation of the absorption process and improving the oil and gas absorption effect.

[0033] Diesel feed flange 14: Located on one side of diesel washing tower 11, it is used to introduce diesel into the interior of diesel washing tower 11 to provide absorbent for oil and gas absorption. It is the inlet for diesel to enter the system to participate in the oil and gas absorption process.

[0034] Oil and gas feed flange 15: Located on the outer surface of the diesel washing tower 11 away from the diesel feed flange 14, it is the channel for oil and gas to enter the diesel washing tower 11, ensuring that the oil and gas can smoothly enter the tower and have reverse contact and absorption reaction with the diesel.

[0035] Circulation pump 16: This is a centrifugal pump with a flow rate of twelve cubic meters per hour. It is connected to the diesel washing tower 11 through a pipeline. Its function is to enable diesel fuel to circulate from top to bottom in the diesel washing tower 11, so that it forms a counter-current contact with the oil and gas from bottom to top, thereby increasing the contact time and area between the oil and gas and the diesel fuel, promoting the dissolution of oil and gas in the diesel fuel, and improving the oil and gas absorption efficiency.

[0036] Oil pump 17: Also a centrifugal pump with a flow rate of 12 cubic meters per hour. One end is connected to the bottom of diesel washing tower 11 through a pipeline, and the other end is connected to the oil storage tank. Its function is to periodically transport the diesel that has lost its adsorption effect in diesel washing tower 11 back to the oil storage tank, so as to ensure that the diesel participating in the absorption always has good adsorption capacity and maintain the continuous and stable operation of the oil and gas absorption process.

[0037] Oil and gas recovery flange 18: Installed on the upper end of the diesel washing tower 11, it is connected to the oil and gas recovery equipment to form a closed loop in the entire oil and gas absorption process; a small amount of unabsorbed oil and gas enters the oil and gas recovery equipment for subsequent treatment through this flange, avoiding oil and gas leakage and further ensuring environmental safety and public safety.

[0038] Magnetic level gauge 19: Fixedly connected to the outer surface of diesel washing tower 11, used to observe the diesel level inside the equipment; on-site personnel can use it to monitor the level in real time so as to adjust the equipment operating parameters in a timely manner, ensuring that the diesel level inside diesel washing tower 11 is within a suitable range, and ensuring the stable and efficient operation of the oil and gas absorption process.

[0039] Working principle:

[0040] In the first step, the diesel washing tower 11 is connected to the circulation pump 16 and the oil pump 17 via pipelines. Both the circulation pump 16 and the oil pump 17 have a flow rate of 12 cubic meters per hour. The other end of the oil pump 17 is connected to the oil storage tank via a pipeline. The diesel feed flange 14 installed on the surface of the diesel washing tower 11 is used for diesel feed. The oil vapor enters the interior of the diesel washing tower 11 through the oil vapor feed flange 15. Through the diesel washing tower 11, the diesel circulates from top to bottom within the equipment, coming into counter-current contact with the oil vapor flowing from bottom to top, causing the oil vapor to dissolve in the diesel. The diesel then flows downwards. At the bottom of the diesel washing tower 11, the diesel fuel that has lost its adsorption effect is periodically transported back to the oil tank by the oil pump 17. The diesel washing tower 11 effectively absorbs oil and gas, avoiding oil waste, reducing the emission of toxic and harmful substances, protecting the environment, reducing harm to human health, eliminating safety hazards caused by oil and gas, and ensuring public safety. The diesel washing tower 11 is connected to the oil and gas recovery equipment through the oil and gas recovery flange 18 to achieve a closed loop. A small amount of oil and gas that is not absorbed enters the oil and gas recovery system through the oil and gas recovery flange 18 for treatment.

[0041] The second step involves using a distributor 13 to ensure uniform distribution of liquid across the tower's cross-section, thereby guaranteeing high-efficiency operation. A wire mesh demister 12 separates mist from the gas to improve operating conditions, optimize process parameters, reduce equipment corrosion, extend equipment lifespan, increase throughput, recover valuable materials, protect the environment, and reduce air pollution. A circulation pump 16 circulates diesel fuel from top to bottom within the equipment, creating a counter-current contact with the rising oil and gas. An oil pump 17 returns diesel fuel that has lost its adsorption effect to the oil storage tank. A magnetic level gauge 19 is used to observe the diesel fuel level within the equipment. By equipping the equipment with a magnetic level gauge 19, the function of monitoring the liquid level by on-site personnel is realized.

[0042] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
