Study on optimal operation of public auxiliary device under low load in Zhongxian Natural Gas Purification Plant

In recent years, with the exploitation of natural gas in the eastern Sichuan area of southwest oil and gas field entering the later stage, the treatment capacity of feed gas of natural gas purification plant, which is the key link in the process of natural gas treatment, has been decreasing year by year. Under the condition of low load, the utility consumption of the unit is large and the energy consumption is high. Based on the analysis of the operation of public auxiliary devices under low load condition in Zhongxian natural gas purification plant, the improvement measures are proposed from the aspects of optimizing process scheme, adopting advanced energy-saving equipment, adjusting on-site operation, summarizing production and operation management experience, etc., and the measures for optimizing the operation of public auxiliary devices are elaborated in detail, contributing to the fully excavation of the energy-saving potential of Zhongxian natural gas purification plant and good economic and environmental benefits.
