先进控制系统在延迟焦化装置的应用现状

Application of Advanced Control System in Delayed Coking Units

针对延迟焦化装置的特点,结合先进控制系统的诸多优点,设计了加热炉炉效率控制器、支路平衡控制器、分馏控制器和吸收稳定控制器。系统投入使用后,可以有效抵御焦炭塔预热、切塔等间歇操作带来的生产波动,既降低了操作人员的劳动强度,又有利于装置的长周期运行,具有良好的经济效益。

According to the characteristics of delayed coking unit,combined with theAPC system,the furnace efficiency controller,branch balance controller,fractionation controller and absorption stability controller are designed.After the system is used,it can effectively resist the production fluctuation caused by the intermittent operation of coke tower preheating and tower switching,which not only reduces the labor intensity of operators,but also is conducive to the long-term operation of the device,and also has good economic benefits.
