摘　　要：安全仪表系统(Safety Instrumented System,简称SIS)是化工企业自动控制中的重要组成部分,对企业的安全生产起着至关重要的作用。通常针状焦生产的焦化工序采用延迟焦化工艺,该工艺装置中高温重油部位较多,且工艺流程长设备易损坏,因此存在较高危险性。本文从系统可靠性、安全性和环境等因素考虑,在延迟焦化工艺中引入符合安全标准的SIS系统,介绍了焦化SIS系统的主要组成和控制逻辑,并提出了安全生产中的表决方式。Safety Instrumented System(SIS)is an important component of automatic control in chemical enterprises,which plays a vital role in safe production.Usually,delayed coking process is adopted in the coking process of needle coke production.There are many high temperature heavy oil parts in the process unit,and the equipment is prone to damage for a long process time,so the process has high risk.Considering the reliability,safety and environment of the system,this paper introduces the SIS system which conforms to the safety standard in delayed coking process,introduces the main composition and control logic of the SIS system,and puts forward the voting method in safe production.
