提到加油站，人們的第一印象多是油味兒刺鼻。如今，中石化駐馬店石油分公司的近百座加油站已經完成了油氣回收改造，加油站內幾乎聞不到汽油味了。以前在加油的時候，明顯能看到油槍嘴的地方，有霧狀的氣體上飄，加油和卸油時散發出濃烈的汽油味。
When it comes to gas stations, people's first impression is often the pungent smell of oil. Nowadays, nearly a hundred gas stations of Sinopec Zhumadian Petroleum Branch have completed oil and gas recovery renovations, and the smell of gasoline is almost non-existent in the gas stations. In the past, when refueling, there was a noticeable mist of gas floating up from the nozzle of the fuel gun, emitting a strong gasoline smell during refueling and unloading.
日前，來到中石化加油站里，幾乎聞不到明顯的汽油味。記者發現在加油槍靠近槍嘴的地方裝上了一個黑色面罩，罩住油箱口后，阻止油氣‘逃’到空氣中。加油機的后端裝有一段軟管，油嘴吸收的油氣，通過軟管進入回收管道，存儲在加油站埋設的油罐里，再由油罐車運回油庫還原成液體汽油。
Recently, when I came to the Sinopec gas station, I could hardly smell the obvious smell of gasoline. The reporter found that a black mask was installed near the nozzle of the fuel gun to cover the fuel tank opening and prevent the oil and gas from 'escaping' into the air. The rear end of the fuel dispenser is equipped with a flexible hose. The oil and gas absorbed by the nozzle enter the recovery pipeline through the hose and are stored in the oil tank buried at the gas station. They are then transported back to the oil depot by tanker trucks to be reduced into liquid gasoline.
油氣回收是節能環保型的高新技術，運用油氣回收技術回收油品在儲運、裝卸、加注過程中排放的油氣，能夠有效降低油氣揮發造成的大氣污染，對浪費的油氣分子進行回收并轉化成汽油，一定程度上節約了資源，油氣回收改造還能消除安全隱患，當空氣中油氣高度聚集，油氣分子與空氣達到一定濃度時，出色易引發爆炸事故，因此對油氣展開回收工作是十分有必要的。
Oil and gas recovery is an energy-saving and environmentally friendly high-tech. The use of oil and gas recovery technology to recover the oil and gas emitted during the storage, transportation, loading and unloading, and refueling processes of oil products can effectively reduce air pollution caused by oil and gas volatilization. Waste oil and gas molecules can be recovered and converted into gasoline, which to some extent saves resources. Oil and gas recovery transformation can also eliminate safety hazards. When oil and gas are highly concentrated in the air and the concentration of oil and gas molecules in the air reaches a certain level, it is very easy to cause explosion accidents. Therefore, it is necessary to carry out oil and gas recovery work.
油氣回收的原理
The principle of oil and gas recovery
1.油氣回收原理及怎么油氣回收，就是通過管線全部聯通形成氣象聯通空間，并通過增加真空泵及卸油車，將產生的油氣回收至油罐車和低標號油罐，如果有后處理裝置，油氣會被吸收至此裝置
1. Principle and method of oil and gas recovery. Oil and gas recovery involves connecting all pipelines to form a meteorological communication space, and by adding vacuum pumps and oil unloading trucks, the generated oil and gas are recovered to oil tank trucks and low-grade oil tanks. If there is a post-treatment device, the oil and gas will be absorbed into this device
2.油氣回收分為加油油氣回收（二次）和卸油油氣回收（一次）以及后處理裝置（三次）
2. Oil and gas recovery is divided into refueling oil and gas recovery (secondary), unloading oil and gas recovery (primary), and post-treatment equipment (tertiary)
卸油油氣回收：將汽油油罐車卸油時產生的油氣回收至油罐車里的密閉油氣回收系統，將油氣拉倒油庫進行后處理。
Unloading oil and gas recovery: The oil and gas generated during the unloading of gasoline tank trucks are recovered into a closed oil and gas recovery system inside the tank truck, and the oil and gas are pulled down to the oil depot for post-treatment.
加油油氣回收系統：將給汽油車輛加油時產生的油氣回收至埋地汽油油罐的密閉油氣回收系統。
Refueling oil and gas recovery system: A closed oil and gas recovery system that recovers the oil and gas generated when refueling gasoline vehicles to buried gasoline tanks.
后處理裝置：針對加油油氣回收系統部分排放的油氣，通過采用吸附、吸收、冷凝、膜分離等方法對這部分排放的油氣進行回收處理的裝置。
Post processing device: A device that recovers and processes the partially discharged oil and gas from the refueling oil and gas recovery system through methods such as adsorption, absorption, condensation, and membrane separation.
