Description

technical field

[0001] The invention relates to the technical field of oil and gas recovery and treatment, in particular to an oil and gas recovery and treatment technology suitable for refineries, gas stations or oil depots, specifically a technology for oil and gas recovery of oil storage tanks, condensing oil and gas recovery technology and membrane Membrane condensing combined oil and gas recovery system which integrates conventional oil and gas recovery technologies. Background technique

[0002] At present, with the progress of society and the improvement of people's living standards, the penetration rate of private cars is becoming wider and wider, resulting in an increase in the number of gas stations. Volatile organic compounds (VOCs), collectively referred to as oil and gas, volatile from gas stations are also increasing, because it is impossible to carry out in a completely sealed environment during the process of gasoline loading and unloading, storage and trans...
