1、摘要天然气调压计量站是天然气输配工程的重要组成部分。其主要任务是调节输气管线的压力、计量气体流量以及脱除天然气中含有的液滴和机械杂质等，在天然气的输送与分配过程中占有重要地位。本文是天然气长输管线中间调压计量站的工艺设计，该站集调压、计量、清管和气体分离功能于一体，是典型的中间调压计量站。长输管线来气在该站经分离后，一部分经调压计量输送至用户；另一部分经计量后进入干线。按照调压计量站应简洁准确、安全可靠、经济高效的设计思路，对该站场主要工艺进行了设计。设计中充分考虑了基本工艺参数和工艺要求，依据相关规范标准，确定了主要设备的设计、选型、安装的原则和方法。在此基础

2、上，对主要设备进行了工艺计算和选型，并绘制了站场的工艺流程图、平面布置图和平面安装图。设计结合了具体工程要求，采用成熟的设计方法和工艺流程，严格遵循最新规范标准及国家有关政策法令，最终完成了一套完整的调压计量站设计方案。关键词：天然气；调压站；计量；设计；工艺流程AbstractNaturalgasregulatingmeteringstationisanimportantcomponentoftheprojectofgastransmissionanddistribution.Itsmajortaskistoregulatethepressureongaspi
