蒸馏装置先进控制的实现

文章介绍了蒸馏装置先进控制实现的方法和特点,以及蒸馏先进控制在传统DCS控制基础上的研发方向和研发内容。从投用结果看,在外界条件相对平稳的情况下,采用先进控制能相对降低工人劳动强度,提高装置平稳率,并提高了产品侧线收率和轻收。其缺点是在外界条件变化时,控制平稳率下降,反应速度较慢。因此,作者最后的结论是装置的控制应采取先进控制与传统的DCS控制结合应用的模式。

Advanced Control Realization of Distillation Unit

The paper described the implementation of advanced control of the distillation unit and features,as well as of distillation advanced control traditional DCS control on the basis of the R & D direction and R & D content.And put in the case of a relatively stable external conditions,the use of advanced control can relatively reduce labor intensity,improve the device steady rate,and improve the product side of the line yield and light received.The disadvantage is the change of the external conditions,control of stable rate decreased reaction rate is slower.Therefore,the author’s final conclusion is the control of the device should be taken advanced control and traditional DCS control combined application mode.
