Q3. A continuous flow distillation column is fed with a binary mixture of A and B. The relative volatility (a) of mixture is constant. Consider the plates above the feed plate. Derive the difference equations which relate the liquid composition to the plate number n, if the overall plate efficiency is 100% and explain the method of solving it. OR An irreversible exothermic reaction is carried out in a single perfectly mixed non- isothermal reactor. The reaction is A k > * > B. The reaction is nth order and has a heat of reaction . Assuming negligible heat losses and constant densities. To remove heat of reaction, a cooling jacket surrounds the reactor. Cooling water is added to the jacket at volumetric flow rate of F; with an inlet temperature of Tjo. The volume of the jacket V; is constant. The mass of metal walls possess significant thermal capacitance. Develop a mathematical model for the non-isothermal CSTR
