Compressor Stations Doing the Difficult Work

摘要

Compressor stations compress and push gas from the field where it is extracted or from an LNG re-gasification import port, along transmission pipelines, to end customers, such as refineries, power stations, or LNG export plants.Compressors, housed in stations located at 40- to 100-mile intervals along a pipeline, run continuously and allow gas to be rerouted into gas storage areas during periods of low demand. An average station can ship 700 Bcf/d of natural gas, while the largest are reported to be able to send 4 Tcf/d of gas.Compressor stations also house pig launchers and receivers, which are maintenance and inspection robots, needed to maintain the efficiency, integrity, and safety of the pipeline and station.
