安全仪表系统在天然气管道系统中的应用

Application of Safety Instrument System in Natural Gas Pipeline System

安全仪表系统(SIS)通过监控天然气管道生产情况,在发现危险条件时,可自动实施相应的功能,可有效防止危险事件的发生和减少危险事件的危害。以公司管道系统的SIS为例,阐述了SIS的基本组成、主要功能,并以从化分输站为典型示例,分析了在不同的紧急情况下,为保障站场运营安全SIS所执行的主要操作。

The safety instrument system（SIS） can automatically implement the corresponding functions by monitoring the production situation of natural gas pipelines when dangerous conditions are found, which can effectively prevent the occurrence of dangerous events and reduce the harm of dangerous events. Taking SIS of pipeline system of the company as an example, this paper expounds the basic composition and main functions of sis, and taking Conghua branch transmission station as a typical example, analyzes the main operations carried out by SIS in different emergency situations to ensure the safety of station operation.
