先进控制系统在延迟焦化装置中的应用

摘要

针对延迟焦化装置的实际工艺条件和操作现状,论述了先进控制系统的控制策略,分别讨论了反应器控制器、吸收稳定系统控制器的关键控制变量,并就软测量的主要功能部分进行了阐述.先进控制系实施后,延迟焦化装置的控制器投用率达到95％以上,提高了装置的自动化水平,减轻了操作人员的劳动强度,实现了装置的平稳运行、装置的“卡边”操作、提高了总液收率,降低了装置的能耗,在炼化生产中具有推广价值.%According to actual process conditions and operation status of delayed coking device,control strategy of advanced control system is discussed.Key control variables of reactor controller and absorber-striper-stabilizer controller are discussed respectively.Main function on soft measurement is also expounded.After implementation of advanced control system,utilization rate of the controller of delayed coking unit increases to 95％ and above.The installation automation is increased,work intensity of operators is alleviated,the stable operation and expert experience operation of the unit are also realized.Yield of valuable products is increased,as well as unit energy consumption is reduced.The system is worth popularizing in refinery production.
