摘要
以长庆气田至呼和浩特天然气管道建设工程为背景,探讨了氮气隔离法置换工艺在天然气长输管道投产中的应用。通过对采用单隔离器和无隔离器的两种天然气置换工艺进行分析比较,得出了无隔离器的氮气隔离置换工艺是目前比较理想的天然气置换工艺。
Based on the construction engineering of the gas pipeline from Changqing to Huhehaote, discusses the application of the gas displacement technology of nitrogen isolation method in the construction of long-distance transmission pipeline. By comparing the two kinds of gas displacement technology, namely one with single cup pig and one without cup pig, a conclusion is drawn that the latter is a more ideal one at present.
