(a)
Interpretation:
A feedback control method is to be proposed for the given distillation column along with a schematic diagram.
Concept introduction:
A control system is a system that regulates or monitors the behavior or working of other devices/systems using control loops. It can be used to control a single device or large industrial processes. There are two types of control system which can be used to control the processes. These are the feedback control system and the feedforward control system.
Feedback control systems consider the output of the system and then compares it with the desired value to adjust the measured value to provide accurate results whereas in the feedforward control system, disturbances are taken into account beforehand and they are rectified to control it from deviating from the desired set point.
Schematic representation of this control system using symbols, lines, and all the controlled, manipulated, and disturbance variables is known as control system diagrams.
