(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.

A toxic organic solute (species A) diffuses into the biofilm and is degraded to harmless products by the cells within the biofilm. We want to treat 0.2 m3 per hour of wastewater containing 0.14 mole/m of the toxic substance phenol using a system consisting of biofilms on rotating disk as shown below. thickness of the biofilm is 1 mm and we are interested to reduce the phenol concentration in the outlet stream to 0.025 mole/m3. The rate of disappearance of phenol (species A) within the biofilm is described by the following equation rA = - KICA Where k1 = 0.0024 s-1 The diffusivity of phenol in the biofilm at the process temperature of 25°C is 2.0x10 10 m2/s. Phenol is equally soluble in both water and the biofilm. 1. The concentration of A in the biofilm is give by Ca = Bisinh(mz) + Bzcosh(mz), the numerical value of m is. 2.

A single-effect evaporator is concentrating a feed solution of organic colloids from 5 to 50 wt %. The solution has a negligible boiling point elevation. The heat capacity of the feed is cp . 4.06 kJ/kg K and the feed enters at 15.6 °C. Saturated steam at 101.32 kPa is available for heating, and the pressure in the vapor space of the evaporator is 15.3 kPa. A total of 4536 kg/h of water is to be evaporated.

A plant wishes to dry a certain type of fiberboard. To determine drying characteristics, a sample of 0.3 × 0.3 m with edges sealed was suspended from a balance and exposed to a current of hot dry air. The initial moisture content was 75%. The sheet lost weight at the rate of 1 104 Kg/s unit the moisture content fell to 60%. It was established that the equilibrium moisture content was 10 %. The dry mass of the sample was 0.90 Kg.
