Distillation Column Control

This exercise is based on a Distillation Column Control. The impact of feed rate on composition control is minimized through the use of feedforward control with dynamic compensation. Heat and composition balances required for stable operation are maintained using heat/feed and distillate/feed ratio control. The Distillation Column Control process and control are shown below.
