西气东输管道增输压气站设置

Setup of Compressor Stations of West to East Gas Pipeline for Increasing Gas Transportation Capacity

西气东输管道是我国目前距离最长、管径最大、压力最高、输量最大的输气管道,原设计商品气输量120亿m3/a,设置10座压气站。根据下游市场情况,2007年要实现增输商品气量50亿m3/a,西气东输管道商品气输量将达到170亿m3/a。西气东输管道增输后全线共有22座压气站,其中增输将新建12座压气站。文章介绍了西气东输管道增输压气站站场设置、驱动方式选择、机组配置、水力计算等。

West to East Gas Pipeline is the largest gas transmission pipeline in China featuring the longest distance, highest pressure and maximum gas transportation capacity. The original designed gas transportation capacity is 120×108 m3/a and has 10 gas compressor stations along the pipeline. According to the downstream market situation, the gas transportation capacity of West to East Gas Pipeline will be increased by 50×108 m3/a and the whole gas transportation capacity will reach 170×108 m3/a in 2007. The compressor stations will be increased by 12 and the whole compressor stations will reach 22. This paper presents the setup of new compressor stations of West to East Gas Pipeline, their driving mode selections, machine unit deployment, hydraulic calculations, etc.
