MODELLING AND ADVANCED PROCESS CONTROL (APC) FOR ...

MODELLING AND ADVANCED PROCESS CONTROL (APC) FOR distillation columns OF LINEAR ALKYLBENZENE PLANT Xiaoming Jin, Gang Rong and Shuqing Wang National Key Lab of Industrial CONTROL Technology, Institute of ADVANCED PROCESS CONTROL , Zhejiang University, 310027, Hangzhou, China email: Abstract: This paper introduces industrial application of model predictive CONTROL (MPC) for the series of columns in a linear alkylbenzene (LAB) complex. The APC system that is consisted of twelve controlled variables, twelve manipulated variables and eight disturbance variables is used to deal with the constrained multivariable CONTROL problem of the distillation columns . Firstly, PROCESS MODELLING that includes experimental test and PROCESS identification is presented. Then, the construction and implementation of the APC system for the distillation columns are discussed.

APC system that deals with whole distillation Distillation columns have been widely used for separation processes in the petroleum and chemical ... columns rather than single column via a MPC ... the overhead condenser. The accumulator level is
