Controllability of Sidestream Distillation Columns

Abstract A control application for a distillation column with one sidestream is developed using an industrial tool for column and control system design. This tool is subject of an industry-university cooperation project under financial support of the government of Nordrhein-Westfalen and the companies Henkel KGaA, Dusseldorf, and Schmidding GmbH&Co., Koln. The supporting system for column and control system design is the result of this cooperation project (Remberg, 1994). Different control systems have been designed and realized in different production plants (Luder, 1992) showing satisfactory performance. Within this paper the structure of the supporting system and the recent developments and extensions will be presented The experiences within the cooperation project will be pointed out.
