Title:
OIL AND GAS PROCESSING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/244639
Kind Code:
A1
Abstract:
Disclosed is an oil and gas processing method, which can achieve high-efficient separation and recovery of gasoline components and C2, C3 and C4 components. Light hydrocarbon components is first separated from gasoline components, and then the stream rich in the light hydrocarbon components is subject to post-processing, and therefore, it is no longer necessary to absorb liquefied gas components by gasoline circulation, so that the gasoline circulation volume is greatly reduced, and the energy consumption of the entire separation process is reduced. Before the component separation process is performed, impurities, such as HZS and mercaptans, in the stream rich in the light hydrocarbon components are removed to ensure that the impurities will not be brought to the downstream light hydrocarbon recovery part, which avoids the corrosion problem related to the recovery of light hydrocarbons caused by hydrogen sulfide, and at the same time, the downstream hydrogen sulfide concentration is greatly reduced, and both safety and the quality of downstream products are improved.
