油氣回收裝置的工藝方案，因石油石化行業的生產儲運環節較為復雜，采用單一的油氣回收技術未能滿足油氣排放要求，故需根據使用場景來定制工藝方案。目前多采用上述技術的組合，如活性炭吸附＋吸附劑吸收組合工藝、冷凝＋膜組合工藝、吸收法 + 活性炭吸附法、多級交接吸附油氣回收工藝等。其中，膜分離技術在石油石化行業的接受度正在增加[13]，隨著技術的成熟，該技術的集成油氣回收應用出色具發展前景。互聯網的發展，同樣推動了油氣回收技術的進步。

　　The process plan for the oil and gas recovery device needs to be customized according to the usage scenario, as the production, storage, and transportation processes in the petroleum and petrochemical industry are complex and the use of a single oil and gas recovery technology cannot meet the requirements for oil and gas emissions. At present, the combination of the above technologies is commonly used, such as activated carbon adsorption+adsorbent absorption combination process, condensation+membrane combination process, absorption method+activated carbon adsorption method, multi-stage transfer adsorption oil and gas recovery process, etc. Among them, the acceptance of membrane separation technology in the petroleum and petrochemical industry is increasing [13]. With the maturity of the technology, the integrated oil and gas recovery application of this technology has great development prospects. The development of the Internet has also promoted the progress of oil and gas recovery technology.

　　油氣回收系統氣密性建議達標！

　　The airtightness of the oil and gas recovery system must meet the standard!

　　環保檢測時，會往油罐系統充入氮氣，使油罐系統氣壓達到500Pa，5分鐘后檢測，油罐系統余壓不能低于規定值。

　　During environmental testing, nitrogen will be injected into the oil tank system to achieve a pressure of 500Pa. After 5 minutes of testing, the residual pressure of the oil tank system cannot be lower than the specified value.

　　第二：地下管道液阻建議達標！

　　Secondly, the liquid resistance of underground pipelines must meet the standard!

　　檢測時，使管道的另一端通暢，往管道充入氮氣，觀察充氣端加裝壓力表數值，此數值即為管道液阻值。

　　During the inspection, ensure that the other end of the pipeline is unobstructed, fill the pipeline with nitrogen, and observe the value of the pressure gauge installed at the inflation end. This value is the resistance value of the pipeline liquid.

　　充入氮氣速度有三檔：18L/min、28 L/min和38 L/min，相應管道的阻力分別不能大于50Pa、90 Pa和155 Pa。

　　The nitrogen filling speed has three levels: 18L/min, 28 L/min, and 38 L/min, and the resistance of the corresponding pipelines cannot exceed 50Pa, 90 Pa, and 155 Pa, respectively.

　　第三：加油時氣液比建議達標！

　　Thirdly, the gas-liquid ratio must meet the standard when refueling!

　　加油時回收的油氣體積與加出去的油液體積之比，即為氣液比。

　　The ratio of the volume of recovered oil and gas to the volume of added oil and liquid during refueling is called the gas-liquid ratio.

　　氣液比合格范圍是：1:1~1.2:1。

　　The qualified range of gas-liquid ratio is 1:1~1.2:1.

　　第四：三次回收尾氣排放濃度建議達標！

　　Fourthly, the concentration of exhaust emissions from the third round of recycling must meet the standard!

　　尾氣排放濃度合格范圍是：不大于25mg/L。

　　The qualified range of exhaust emission concentration is not greater than 25mg/L.

　　目前，國內的相關環保標準日趨完善，主要有 GB20950-2020 《儲油庫大氣污染物排放標準》、JTS196-12-2017 《碼頭油氣回收設施建設技術規范 (試行)》、GB 31570-2015 《石油煉制工業污染物排放標準》和 GB 20952-2020《加油站大氣污染物排放標準》。

　　At present, the relevant environmental standards in China are becoming increasingly perfect, mainly including GB20950-2020 "Emission Standards for Air Pollutants from Oil Storage Tanks", JTS196-12-2017 "Technical Specifications for Construction of Oil and Gas Recovery Facilities at Ports (Trial)", GB 31570-2015 "Emission Standards for Pollutants from Petroleum Refining Industry" and GB 20952-2020 "Emission Standards for Air Pollutants from Gas Stations".

　　而國外相關標準主要有：美國南加州空氣質量管理局(SCAQA) 的相關法規《有機液體裝載》(Rule 462)、《有機液體儲存》(Rule 463) 和《海上游船操作》(Rule1142)；歐共體《關于遠距離越境空氣污染的 1979 公約》和《汽油儲存和從儲油庫向加油站配送汽油過程的揮發性有機物 (VOCs) 排放控制》(94/63/EC)；德國《關于執行汽油、石腦油等儲存或轉移過程中揮發性有機化合物的排放控制》(第 20 號 BImSchV)。

　　And the relevant standards abroad mainly include: the regulations of the Southern California Air Quality Administration (SCAQA), such as "Organic Liquid Loading" (Rule 462), "Organic Liquid Storage" (Rule 463), and "Marine Cruise Operations" (Rule 1142); The European Community's 1979 Convention on Long Range Transboundary Air Pollution and the Control of Volatile Organic Compounds (VOCs) Emissions from Gasoline Storage and Distribution from Storage Tanks to Gas Stations (94/63/EC); Germany's "Emission Control of Volatile Organic Compounds during Storage or Transfer of Gasoline, Naphtha, etc." (No. 20 BImChV).
