汽油挥发产生的油气，学名 挥发性有机物（VOCs），是灰霾、光化学烟雾的“幕后推手”。它们不仅污染大气、刺激人体，更可能在静电或明火下瞬间爆炸。法规早已明确：储油库、加油加气站必须安装油气回收装置， 把“跑冒滴漏”的油气变成汽油重新回罐，既减排又省钱。

The volatile organic compounds (VOCs) produced by the volatilization of gasoline are the "driving force" behind haze and photochemical smog. They not only pollute the atmosphere and irritate the human body, but also have the potential to explode instantly under static electricity or open flames. The regulations have long been clear: oil storage tanks and refueling stations must install oil and gas recovery devices to convert "leaking" oil and gas into gasoline and recycle it back into tanks, which not only reduces emissions but also saves money.

油气回收到底分几次？

How many times is oil and gas recovery divided?

△ 一次回收：卸油时“截胡”

△ One time recycling: "Cut off Hu" during oil unloading

油罐车卸油时， 罐内压力升高把油气顶出来，通过连接管回到油库储罐，这一步叫一次回收。

When an oil tanker unloads oil, the pressure inside the tank rises, pushing the oil and gas out and returning to the oil storage tank through a connecting pipe. This step is called a recovery.

△ 二次回收：加油时“抽真空”

Secondary recycling: Vacuum pumping during refueling

车主加油时， 回收枪把油箱上方油气抽回地下储罐，减少加油口逸散，这是日常最直观的环节。

When the car owner refuels, the recovery gun draws the oil and gas above the fuel tank back to the underground storage tank, reducing the leakage of the refueling port. This is the most intuitive part of daily life.

△ 三次回收：储罐“深呼吸”

Three times recycling: tank "deep breathing"

当储罐内油气浓度达到设定值， 三次油气回收装置自动启动冷凝液化，把剩余油气变回汽油重新注入罐内，完成闭环。

When the concentration of oil and gas in the storage tank reaches the set value, the tertiary oil and gas recovery device automatically starts condensation liquefaction, turning the remaining oil and gas back into gasoline and re injecting it into the tank, completing the closed-loop process.

一套系统如何“抓”住油气？

How can a system capture oil and gas?

加油站油气回收系统由五大件组成：

The gas station oil and gas recovery system consists of five major components:

卸油油气回收管——把车顶的油气带回油库

Unloading oil and gas recovery pipe - bringing the oil and gas from the roof back to the oil depot

密闭汽油储存罐——杜绝呼吸孔直排

Sealed gasoline storage tank - eliminate direct discharge from breathing holes

二次回收加油枪+真空泵——把油箱上方油气吸走

Secondary recycling fuel gun+vacuum pump - suck up the oil and gas above the fuel tank

在线监测探头——实时比对气液比、压力

Online monitoring probe - real-time comparison of gas-liquid ratio and pressure

油气处理装置——冷凝、吸附或膜分离，把气变液

Oil and gas processing equipment - condensation, adsorption or membrane separation, converting gas into liquid
