摘　　要：精细化工生产过程中,氧化反应是国家安全监管总局重点监管的危险化工工艺,其有反应剧烈、突变性强及危险系数高等特点,整个反应过程控制中对温度、压力、液位等仪表测量参数必须要有足够的把握和可靠的控制。结合工厂实际生产中所运用的基本过程控制(DCS)和安全仪表系统(SIS)两套基本控制和安全联锁系统,着重介绍氧化反应过程中的温度、压力、液位等参数基本过程控制方案以及失控下的安全控制联锁保护。本文的过程控制方案和安全联锁在实际生产中已经经过验证,其运行稳定及可靠性高,因此在生产中对于相似的氧化反应流程具有学习借鉴意义。In the production process of fine chemicals, oxidation reaction is a dangerous chemical process under the supervision of the State Administration of State Security, which has the characteristics of violent reaction, strong mutation and high risk factor,and the measurement parameters of temperature, pressure, liquid level and other instruments must be sufficiently grasped and reliably controlled in the whole reaction process control. Combining the basic process control(DCS)and safety instrumented system(SIS)two basic control and safety interlocking systems used in the actual production of the factory, it focuses on the basic process control scheme of temperature, pressure, liquid level and other parameters in the oxidation reaction process and the safety control chain protection under uncontrolled control. The process control scheme and safety interlocking in this paper have been verified in actual production, and their operation is stable and reliable, so it has learning significance for similar oxidation reaction processes in production.
