Abstract

The invention belongs to the field of oil and gas recovery, and particularly relates to an oil and gas recovery device and a recovery method thereof. The oil and gas recovery device comprises an oil and gas collection system, an oil and gas recovery system and a carrier gas circulation system, wherein the oil and gas collection system comprises at least one oil product storage tank, at least one primary liquid separation tank and a heat exchanger; the oil and gas recovery system comprises a secondary liquid separation tank, a compressor and a condenser; the carrier gas circulation system comprises a carrier gas tank, an adsorption tower and a desorption tank. The oil and gas recovery device and the recovery method thereof adopt closed circulation design, recycle discharged gas after oil and gas recovery, greatly reduce discharged air pollutant, ensure that oil product recovery percent approximately can reach 100 percent, are low in operation cost and short in investment recovery period, have obvious economic benefit and ecological benefit, and are suitable for promotion and application.

Description

technical field [0001] The invention belongs to the technical field of oil gas recovery, and relates to an oil gas recovery device and a recovery method thereof. Background technique [0002] During the production, storage, transportation, sales or use of gasoline and other light oil products, due to the influence of temperature, air pressure, changes in the volume of the gas-liquid phase in the oil storage tank and other factors, some of the oil and gas will volatilize and directly escape into the atmosphere. The loss of oil and gas will not only cause environmental pollution, but also bring economic losses, and there will be safety hazards in thunderstorms. In recent years, with the gradual enhancement of people's awareness of environmental protection, the country and enterprises have paid more and more attention to environmental pollution issues, reducing the emission of gas pollutants in oil storage tank farms is an important means to protect the environment and improve ...
