Development and Optimization of the Process Operation Program in Sichuan to Eastern China Gas Pipeline

天然气长输管道运行较为复杂,确定出科学、合理、高效节能的生产运行方案是管道运营企业追求的目标。通过对川气东送管道工艺系统进行分析,确定其主要工艺参数运行范围;利用SPS管道仿真软件进行模拟计算,对输气能力进行评估;并对不同输量下管存调节范围进行分析,结合管道运行特点及节能要求,提出优选方案原则及步骤;基于该管道2015—2016年冬季运行情况,证明了该方法具有较强的适应性,制定和优化出的生产运行方案可靠、有效,能够为管道的运行提供指导和决策。

The operation of long-distance natural gas transmission pipelines is very complex, and pipeline companies pursue to develop a scientific, reasonable, highly efficient and energy-saving production program. Through analysis on the process system of Sichuan to eastern China gas transmission pipeline, the operation ranges of main technological parameters are determined. Then SPS pipeline simulation software is used to do analog computation and assess gas transmission capacity of the pipeline. By analyzing the pipeline storage ranges under different flow conditions and combing with the characteristics of pipeline operation and energy saving requirements, principles and procedures of the optimal program is proposed. Based on the operation conditions of the pipeline in winter of 2015 and 2016, the above program is proved to be strongly adaptable, which shows that the operation program which is developed and optimized is reliable, effective and can be utilized to provide guidance and decision making for the pipeline production and operation.
