MODEL PREDICTIVE CONTROL OF SHELL BENCHMARK PROCESS Shiruz Amjad and H. N. Al-Duwuish King Fahd University of Petroleum and Minerals, Department of Electrical Engineering Dhahran, Saudi Arabia [ shiraz, hduwaish] @kfupm.edu.sa ABSTRACT shown. Section 3 contains a :short outline of the control objectives for the column and the performance of the Simultaneous control of overhead and bottoms designed controller is discussed. composition in a binary distillation column using reflux and steam flow as the manipulated variables often proves 2. IDENTIFICATION to he particularly difficult because of the interaction inherent in the process. The development of model based In this paper the control of a high purity binary distillation control (ME) theory in the past 20-25 years has column with 35 trays (see Fi::ure 1) is considered. The provided a framework which caters for the above main purpose of the binary column is to remove a light- distillation control problem. MPC technology has key impurity from the colum~ feed stream such that the penetrated a significant portion of the process industries impurity does not reach a downstream reaction system and harvested large economical benefits. In this paper PI. model predictive controller is proposed for the control of a two-input-two-output high punty shell distillation column. The use of this controller allows for the impurity and pressure control to he decoupled while simultaneously satisfying column operating ...
