Industrial Experience with Double Quality Control

  • Henk Leegwater

Abstract

In this chapter the background of multivariable control will be discussed. Two real industrial experiences are presented. The control structure of two similar separations, but with different process configurations, will be worked out in more detail. Both applications are ethylene-ethane separations. One has a separate reboiler and condenser, and an intermediate reboiler, whereas the other has heat integration by combining a reboiler-reflux condenser. Both applications have been in operation for more than six years.
