Analysis and modernization of gas production systems from compressor station equipment

Mitigating methane emissions into the atmosphere to reduce adverse effects on the environment and climate is a primary goal of the environmental strategies employed by PJSC Gazprom and the Russian Federation as a whole. Experts warn that the planet is confronting a critical situation due to greenhouse gas emissions. This study examines the most effective technologies currently available for recovering gas from compressor station equipment. Based on an assessment of their strengths and weaknesses, a new system known as the Mobile Ejector Unit (MEU) has been proposed. The MEU utilizes a two-stage jet ejector, with its key characteristics derived from calculations based on G.N. Abramovich's methodology. Additionally, the study presents modification schemes for the valve unit to facilitate the MEU's connection, as well as gas recovery schemes from the centrifugal booster circuit and the compressor workshop circuit. An analysis of evacuation times based on different recovery schemes was conducted, along with an economic assessment of the MEU's implementation efficiency. The findings indicate that this technology is both effective and adaptable, owing to its operational simplicity, cost efficiency, and mobility.
