- 摘要:
天然气处理脱水工艺中利用焦耳—汤姆逊节流膨胀阀(以下简称J-T阀)降低天然气温度,以达到脱水工艺要求。脱水工艺过程中J-T阀前后有大量的压力能未被利用。由于J-T阀脱水工艺中天然气高压、含液,余压发电技术一直未能在J-T阀脱水工艺中应用。通过对某脱水脱烃装置现有工艺进行余压发电利用改造,提出相关优化措施,实现压力能的充分利用,达到节能、减排目的。余压发电技术对绿色能源利用的开拓具有参考意义。
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.
