本文以通过实际工程项目为例,分析了通过设内涂层减小管道内壁粗糙度对提高输气效率在设计和运行中意义;还提到了在压气站设计的时候如何提高压气站的效率,降低压气站的能耗,通过这两方面分析,对天然气长输管道的设计和运行中既满足管道需要的输气能力又能降低工程投资和运行成本有一定的指导意义。
In this paper, the actual engineering project is taken as an example to analyze the significance of improving the gas transmission efficiency by reducing the roughness of the inner wall of pipeline in the design and operation by setting the inner coating; how to improve the efficiency of the compressor station when designing the compressor station, Reduce the gas station energy consumption, through these two aspects of analysis, the natural gas long-distance pipeline design and operation not only meet the pipeline needs of the gas transmission capacity but also reduce the project investment and operating costs have some guidance.
