Problems solved by technology

The adsorption separation device of the present invention is simple, has a certain effect in the recovery and treatment of oil and gas, and has a certain degree of guarantee in terms of safety control. However, simple and single adsorption treatment is difficult for oil and gas with multiple components. To achieve high-efficiency recovery, and then inevitably make the exhaust gas pollute the environment, and at the same time
As a result, the distribution and content of the recovered product components cannot meet the corresponding use standards, and there are reprocessing problems in its reuse. Therefore, although the scope of application is wide, it is not suitable for popularization and application.

Abstract

The invention relates to an oil-gas recycling system and an oil-gas recycling process. The system comprises a gas-liquid separation device, an absorption intake separation device, an intake separation device and a storage device. The storage device is connected with the gas-liquid separation device and the intake separation device respectively. The gas-liquid separation device is connected with the intake separation device which is connected with the absorption intake separation device. The absorption intake separation device is above first stage. The intake separation device is also above first stage. By the oil-gas recycling system, combination of multiple separation techniques is achieved, the recycling process by combining multistage intake and absorption intake is achieved, hydrocarbon components in oil and gas can be recycled completely and thoroughly, and energy waste is avoided. The oil-gas recycling system is evident in environment protection effect, low in economic cost, convenient and safe to operate, and suitable for popularization and application in related hydrocarbon-contained oil-gas recycling fields.

Description

technical field [0001] The invention relates to the technical field of oil and gas treatment, in particular to an oil and gas recovery and treatment system and a recovery and treatment process thereof. Background technique [0002] At present, during the exploitation, processing and application of crude oil and other oil products, it is often accompanied by a large amount of oil energy waste and environmental pollution caused by oil gas discharge or incineration, and seriously affects the health and life of relevant people. Therefore, it is urgent It is necessary to research and develop technologies that can effectively recover these oil gases. [0003] In the prior art, the invention patent ZL200710012088.9 relates to a method of oil and gas recovery, which adopts the oil and gas recovery process of cooling-condensation-adsorption-vacuum regeneration-regeneration gas cycle, and the cooling medium used in the cooling step is condensed oil and gas. This invention makes the s...
