Is there a consensus about a distillation column distributed control system (DCS) control strategy? Much has been written about this topic, covering configuration possibilities, constraints and interacting control considerations.
Is there a consensus about a distillation column distributed control system (DCS) control strategy? Much has been written about this topic, covering configuration possibilities, constraints and interacting control considerations. This article proposes a default DCS configuration to serve as a basis. Deviations from the basis are permitted, though reasons for these deviations should be discussed and understood.
Can one DCS configuration be valid for most cases?
Distillation columns typically fractionate a mixture of components into a light boiling fraction (distillate) and a heavy boiling one (bottom). The control strategy must first set distillate yield (or cut) correctly to draw all the
