The Unit Operations Laboratory consists of a Continuous Distillation pilot-plant (Figure 1). The plant is mainly composed of a mash-packing column, pre-heater with electrical resistor, a condenser, feed pump and a double-pipe heat exchanger. The pre-heater is used to heat up the raw material that is fed into the column on a continuous basis. The pre-heating system has not been used since the beginning of lockdown (March 2020). This often has detrimental effects on the performance of the pre-heater. You are required to perform a pre-liminary design study to investigate the extent of loss on the performance. The resister is operated to release 38.3% of its maximum capacity (W) and is used to heat the water to a state of saturated steam at a vapour pressure of 2500 dyn/cm².
