长输天然气管道投产技术

Commissioning Technology of Long-distance Gas Transmission Pipeline

    摘要
  • 摘要: 介绍了目前国内外天然气管道常用的干燥方法。从天然气管道投产作业方案及现场准备、干燥、置换和升压四个方面阐述了长输天然气管道投产技术与注意事项。分析了影响干燥时间的主要因素, 给出了干燥时间、燃气置换所需流量和累积气量的估算方法。

     

    Abstract: The paper introduces common dewatering methods of long—distance gas transmission pipelines at home and abroad.Commissioning technology and requirements of gas pipeline are described from four aspects of implement program／field preparation，dewatering，gas displacement and pressure boosting.Primary factors influencing on drying time are analyzed.Estimation method for drying period，flowrate and gas volume accumulation needed in gas displacement are given.
