摘要
该文介绍了安全仪表系统设计原则和安全完整性等级的划分,以延长气田天然气净化厂为例,从设计角度出发,对处理厂安全仪表系统各部分设计做了详细论述,对关键的关断级别、因果逻辑图和硬手操台设置也进行了论述。
Discribe the diesign principle of safety instrument system and division of safety integrity level,take natural gas process station of Yanchang gas filed as example,from the aspect of design,the detail parts of safety instrument system are described,shutdown level,cause-effect graph and operating panel are also included.
