活性炭吸附油气回收装置：由分液罐、炭床、真空泵、吸收塔等组成。油气混合气体先通过分液罐分离携带的凝液，然后进入处于吸附状态的炭床，烃类气体被活性炭吸附，净化后的气体被排入大气。吸附饱和的炭床采用真空解析，再通过吸收或其他方法转变成液体汽油，实现油气回收

Activated carbon adsorption oil and gas recovery device: composed of a separation tank, carbon bed, vacuum pump, absorption tower, etc. The mixed gas of oil and gas is first separated from the condensate carried by the separation tank, and then enters the adsorption state of the carbon bed. The hydrocarbon gas is adsorbed by activated carbon, and the purified gas is discharged into the atmosphere. The adsorption saturated carbon bed is vacuum analyzed and then converted into liquid gasoline through absorption or other methods to achieve oil and gas recovery

冷凝油气回收装置：主要由换热预冷设备和机械制冷设备组成。油气经换热预冷和机械制冷设备冷却降温后冷凝为液体，再被回收利用。换热预冷为单级冷却系统，由引风机和预冷器组成；机械制冷为多级制冷系统，通过不同级别的压缩机和风冷器制冷机组将油气温度降低，实现油气冷凝

Condensed oil and gas recovery device: mainly composed of heat exchange pre cooling equipment and mechanical refrigeration equipment. Oil and gas are condensed into liquid after being pre cooled through heat exchange and cooled down by mechanical refrigeration equipment, and then recycled and reused. Heat exchange pre cooling is a single-stage cooling system consisting of an induced draft fan and a pre cooler; Mechanical refrigeration is a multi-stage refrigeration system that reduces the temperature of oil and gas through different levels of compressors and air-cooled refrigeration units, achieving oil and gas condensation

膜分离油气回收装置：包含压缩机、膜分离器等核心设备。含烃气体经加压后送至膜分离器，在有选择性的有机膜上，油气比空气具有更高的穿透性，含烃气体被分离成富油物流与贫油物流，富油物流油气再被油品吸收下来，贫油气的滞留物经再处理达标后作为净化气体排放

Membrane separation oil and gas recovery device: including core equipment such as compressors and membrane separators. The hydrocarbon containing gas is pressurized and sent to a membrane separator. On a selective organic membrane, oil and gas have higher permeability than air. The hydrocarbon containing gas is separated into a rich oil stream and a lean oil stream. The oil and gas in the rich oil stream are then absorbed by the oil product, and the residue in the lean oil and gas is treated to meet standards before being discharged as purified gas

吸收法油气回收装置：通常由吸收塔、解吸罐等构成。储运过程中产生的含烃气体进入吸收塔，吸收剂与油气逆流接触，油气被吸收，吸收了油气的富吸收剂经过解吸，解吸出来的油气再用油品进行吸收

Absorption method oil and gas recovery device: usually composed of absorption tower, desorption tank, etc. The hydrocarbon containing gases generated during storage and transportation enter the absorption tower, and the absorbent contacts with the oil and gas in reverse flow. The oil and gas are absorbed, and the rich absorbent that absorbs the oil and gas is desorbed. The desorbed oil and gas are then absorbed by the oil product
