天然气长输管道分输站升压事故推演研究

Study on the Extrapolation of the Accident Caused by Pressure Lifting in the Sub-station of Natural Gas Pipeline

天然气管道事故发生后,对发生事故的原因及人员责任划分都需要有科学的分析作为依据。本文通过利用FLUENT、TGNET等软件对某分输站升压事故过程进行数值模拟,验证分输站在事故发生时所做操作是否与当时操作人员讲述一致,工艺设施内部参数变化对事故设施有多大影响进行分析。

After the occurrence of the natural gas pipeline accident,the causes of the accident and the division of personnel responsibility should be based on scientific analysis.In this paper,FLUENT,TGNET and other software were used to conduct numerical simulation on the process of the pressure lifting accident of a sub-transmission station,to verify whether the operation of the sub-transmission station at the time of the accident was consistent with that of the operators at that time,and to analyze the influence of the changes of internal parameters of the process facility on the accident facility.
