天然气分输站场调压系统安全设计浅析

Brief discussion of nature gas distributing station voltage-regulating system safety design

天然气项目是关系到国计民生的重要项目,其长输管道上分输站场众多,分输站场中需要有调压系统为下游用户供气服务。本文主要对比分析了我国天然气和欧洲天然气调压系统的相关标准,分析了常用的天然气调压系统,讨论了调压流程及调压阀的选择,阐述了调压节流过程中降温的影响和应对,并总结了调压系统安全设计的注意事项。

Nature gas is an important project that related to national economy and people's livelihood, there are many gas distributing stations on its long-distance pipelines, the gas distributing station needs voltage-regulating system to supply gas services for downstream users. This article mainly contrast and analyzed the voltage-regulating system relevant standards of our country nature gas and European, analyzed our country common nature gas voltage-regulating system, discussed the choices of pressure regulating process and pressure regulating valve, analyzed the influences and countermeasures of temperature drop in the regulating throttling process, and summarized the announcements of voltage-regulating system safety design.
