油气回收装置的工艺方案，因石油石化行业的生产储运环节较为复杂，采用单一的油气回收技术未能满足油气排放要求，故需根据使用场景来定制工艺方案。目前多采用上述技术的组合，如活性炭吸附＋吸附剂吸收组合工艺、冷凝＋膜组合工艺、吸收法 + 活性炭吸附法、多级交接吸附油气回收工艺等。其中，膜分离技术在石油石化行业的接受度正在增加[13]，随着技术的成熟，该技术的集成油气回收应用极具发展前景。互联网的发展，同样推动了油气回收技术的进步。

　　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.

　　油气回收系统气密性必须达标！

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

　　环保检测时，会往油罐系统充入氮气，使油罐系统气压达到500Pa，5分钟后检测，油罐系统余压不能低于规定值。

　　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：地下管道液阻必须达标！

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

　　检测时，使管道的另一端通畅，往管道充入氮气，观察充气端加装压力表数值，此数值即为管道液阻值。

　　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.

　　充入氮气速度有三档：18L/min、28 L/min和38 L/min，相应管道的阻力分别不能大于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：加油时气液比必须达标！

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

　　加油时回收的油气体积与加出去的油液体积之比，即为气液比。

　　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.

　　气液比合格范围是：1:1~1.2:1。

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

　　第四：三次回收尾气排放浓度必须达标！

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

　　尾气排放浓度合格范围是：不大于25mg/L。

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

　　目前，国内的相关环保标准日趋完善，主要有 GB20950-2020 《储油库大气污染物排放标准》、JTS196-12-2017 《码头油气回收设施建设技术规范 (试行)》、GB 31570-2015 《石油炼制工业污染物排放标准》和 GB 20952-2020《加油站大气污染物排放标准》。

　　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".

　　而国外相关标准主要有：美国南加州空气质量管理局(SCAQA) 的相关法规《有机液体装载》(Rule 462)、《有机液体储存》(Rule 463) 和《海上游船操作》(Rule1142)；欧共体《关于远距离越境空气污染的 1979 公约》和《汽油储存和从储油库向加油站配送汽油过程的挥发性有机物 (VOCs) 排放控制》(94/63/EC)；德国《关于执行汽油、石脑油等储存或转移过程中挥发性有机化合物的排放控制》(第 20 号 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).
