The press gas station along the pipeline is divided into the starting point for compressor stations, gas compression stations in the middle and the end of filling stations. The starting point for gas compression stations located in the vicinity of the gas field gas gathering center or processing plant, gas pressure, and gas purification, gas mixture, pressure regulators, gas metering, pigging send operations. Intermediate compressor stations located along the pipelines, mainly to the consumption in the transportation of gas pressure booster. The end of filling stations in the gas storage library, will lose to gas pressure into underground gas storage. The three parts of the flow of the gas compression stations by the gas process, unit control and auxiliary systems. In addition to the process of purification, measurement, booster gas technology section also includes and more stations bypass pigging receive and send safety vent and emergency truncated pipeline. The control section of the unit start, overpressure protection, anti-surge circulation line. The auxiliary parts of the system including the supply of fuel gas, automatic control, cooling, lubrication system. Design Guyuan pressure gas station time design basis (relevant norms and book volumes) access to a large number of compressor stations on the information literatu
