Abstract: Process technological flow and operating parameters of 2nd Processing Plant in Kela 2# Gas Field are introduced. Experiment and analysis are performed on the determination of relative parameters in circulation volume of triethylene glycol (TEG), temperature of reboiler, the volume of stripping gas and temperature of lean solution into absorption column, and optimal operating parameters are obtained, which can meet the needs of gas quality of gas transmitted and ensure safe running of processing equipments.
