Sketch a control system diagram for a distillation column. Clearly show signals, signal directions, sensors, control valves, and controller. The objectives of the control system are: (a) Reflux drum level is controlled by a cascade controller which manipulates the controller point of the distillate flow rate; (b) Reflux flow rate back to the column is controlled by a ratio control scheme which maintains specified reflux to distillate ratio; (c) The specified reflux to distillate ratio can be changed by a composition controller at the distillate
