油氣回收裝置的工藝方案，因石油石化行業(yè)的生產(chǎn)儲運環(huán)節(jié)較為復(fù)雜，采用單一的油氣回收技術(shù)未能滿足油氣排放要求，故需根據(jù)使用場景來定制工藝方案。目前多采用上述技術(shù)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(shù)在石油石化行業(yè)的接受度正在增加[13]，隨著技術(shù)的成熟，該技術(shù)的集成油氣回收應(yīng)用極具發(fā)展前景?；ヂ?lián)網(wǎng)的發(fā)展，同樣推動了油氣回收技術(shù)的進(jìn)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(tǒng)氣密性必須達(dá)標(biāo)！

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

　　環(huán)保檢測時，會往油罐系統(tǒng)充入氮氣，使油罐系統(tǒng)氣壓達(dá)到500Pa，5分鐘后檢測，油罐系統(tǒng)余壓不能低于規(guī)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：地下管道液阻必須達(dá)標(biāo)！

　　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(shù)值，此數(shù)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(yīng)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：加油時氣液比必須達(dá)標(biāo)！

　　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必須達(dá)標(biāo)！

　　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(nèi)的相關(guān)環(huán)保標(biāo)準(zhǔn)日趨完善，主要有 GB20950-2020 《儲油庫大氣污染物排放標(biāo)準(zhǔn)》、JTS196-12-2017 《碼頭油氣回收設(shè)施建設(shè)技術(shù)規(guī)范 (試行)》、GB 31570-2015 《石油煉制工業(yè)污染物排放標(biāo)準(zhǔn)》和 GB 20952-2020《加油站大氣污染物排放標(biāo)準(zhǔn)》。

　　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(guān)標(biāo)準(zhǔn)主要有：美國南加州空氣質(zhì)量管理局(SCAQA) 的相關(guān)法規(guī)《有機(jī)液體裝載》(Rule 462)、《有機(jī)液體儲存》(Rule 463) 和《海上游船操作》(Rule1142)；歐共體《關(guān)于遠(yuǎn)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(fā)性有機(jī)物 (VOCs) 排放控制》(94/63/EC)；德國《關(guān)于執(zhí)行汽油、石腦油等儲存或轉(zhuǎn)移過程中揮發(fā)性有機(jī)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).
