In the natural gas dehydration process,the J-T expansion/throttling valve(hereinafter referred to as the J-T valve)is used to reduce the temperature of natural gas to meet the requirements of the dehydration process.In this process,there is a huge amount of unutilised pressure energy before and after the J-T valve.However,due to the presence of liquid in the high-pressure natural gas in the J-T valve dehydration process,the power generation technology using natural gas residual pressure has not been applied in the J-T valve dehydration process before.This article analyzes the process conversion to residual pressure power generation in the expansion project of the existing system for water and hydrocarbon dew point control.Relevant optimization measures are proposed to achieve energy conservation and emission reduction via the optimal utilization of pressure energy.This technology provides reference for the expansion of green energy utilization.
