Problems solved by technology

The system adopts the technical scheme of three-stage condensation, intermediate pressurization and tail gas recovery, so that the volatilized oil gas can be recovered, and the energy saving effect is better. However, the multi-stage condensation setting of the system inevitably has large power consumption, Due to the complex distribution of equipment, high environmental requirements and high cost, it is not suitable for popularization and application, especially in the large-scale recovery of crude oil and gas.

Abstract

The invention relates to an absorption oil-gas recycling system and an absorption oil-gas recycling process. The system comprises an absorption device, a desorption device, an intake device and a storage device, which are connected with one another. The absorption device and the desorption device are more first-staged. By the absorption oil-gas recycling system, the recycling process by combining multistage absorption and desorption is achieved, the problems of pollution and waste of hydrocarbon components in oil and gas are solved, external environment is protected effectively, and energy is utilized efficiently and economically. The absorption oil-gas recycling system is suitable for popularization and application in related oil-gas recycling fields, especially suitable for fields such as lean oil recycling and reusing and crude oil-gas recycling and reusing.

Description

technical field [0001] The invention relates to an oil gas recovery treatment system and a recovery treatment process thereof, in particular to an adsorption type oil gas recovery treatment system and a recovery treatment process thereof. Background technique [0002] At present, in the process of crude oil extraction, processing and application, oil and gas are basically produced. The escape or incineration of these oil and gas mainly has two effects. On the one hand, it causes a large amount of light oil energy waste, and on the other hand, it causes environmental pollution. It is the air pollution that seriously affects the health of the relevant people. Therefore, it is urgent to research and develop technologies that can effectively recover these oil gases. [0003] In the prior art, the patent CN201626827U provides a condensation oil vapor recovery system, which can be applied to the recovery of volatile oil vapor with low carbon content such as crude oil and gasoline ...
