A flow of 100 kmol/h of a saturated liquid mixture containing 40 mol% n-pentane and 60 mol% n-hexane will be separated by continuous distillation. The distilled product contains 95% of the feed n-pentane and the residue product contains 97% of the feed n-hexane. The distillation column operates at a pressure of 25 psia. A total condenser will be used in this process. a) determine the minimum number of stages required for the separation, and b) the minimum reflux ratio. c) if the operating reflux ratio is 1.2 times the minimum, how many stages will be necessary for the separation? d) determine the thermal loads of the condenser and reboiler. Write down all assumptions and assumptions necessary for the analysis of the distillation process. Clearly establish the source from which you will obtain thermodynamic data for system analysis.
