Abstract

The invention discloses a membrane and condensation combined oil-gas recovery system, comprising an oil storage tank (15) provided with a gas-liquid separator (2); a micro pressure sensor (1) is installed on a pipe between the oil storage tank (15) and the gas-liquid separator (2) , the gas-liquid separator (2) is connected with a liquid ring compressor (6) through an oil gas inlet pipe (17) provided with an air inlet solenoid (3a); the liquid ring compressor (6) is connected with a condenser group (7) through a pipe; the condenser group (7) is connected with a membrane assembly (9) through the pipe; the membrane assembly (9) is connected with the liquid ring compressor (6) through an oil gas exhaust gas return pipe (18) with a non-methane hydrocarbon detector (13); the oil gas exhaust gas return pipe (18) is provided with an exhaust pipe; and the permeation side of the membrane assembly (9) is connected with the liquid ring compressor (6) through an enrichment oil gas return pipe (19) with a vacuum pump (11). The membrane and condensation combined oil-gas recovery system has the characteristics of environment protection, high automatic degree, economy and efficiency.

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...
