Question
The benzene-toluene liquid mixture will be separated at 1 atm pressure in a continuous multistage distillation column. The malce at a flow rate of 100 kmol / h enters the feed column containing 45% benzene and 55% toluene at 327.6 K. 95% benzene is required in the upper product and 90% toluene in the lower product. The rate of reflux in the column is 4. Since the average heat capacity is 150 kJ / kmol.K and the average latent heat is 32099 kJ / kmol, calculate the following. A) Bottom product and upstream flow rates of feed. b) The required theoretical number of steps. c) Fluid and vapor flow rates in the enrichment and stripping zones. d) Calculate the minimum flow rate. e) Minimum number of stages .Calculate the heat that needs to be removed from the concentrator and given to the boiler.
