Type: article
Abstract: This paper examines the features of compression of low-pressure high- density associated petroleum gas by screw oil-filled compressors in a cold climate using the example of the Karachaganak field. An analysis of the operating experience of booster compressor units revealed a number of problems related to oil release from the oil system, condensation formation in the compressor's working cells and oil circulation disruption at low temperatures. To solve these problems, a comprehensive approach has been proposed, including equipment modernization and optimization of operating modes. In particular, high-speed inlet shut-off valves have been developed and implemented to prevent oil emissions, the operating temperatures of oil and gas have been increased to reduce condensation, and the heat exchange system has been upgraded to improve oil circulation at subzero temperatures. The research results have shown a significant increase in the reliability and efficiency of compressor units after the implementation of the proposed solutions, which makes it possible to increase the volume of recycled associated petroleum gas and reduce the negative impact on the environment
