A distillation column separates a binary mixture of 2 - butanol ( component 1 ) and 2 - propanol ( or isopropyl - alcohol, component
A distillation column separates a binary mixture of butanol component and propanol
or isopropylalcohol, component into almost pure butanol at the bottom mol pure and almost pure propanol in the distillate mol pure The feed stream kmolhr is a saturated liquid with molpropanol.
a Determine the proper fluid package needed to model this distillation problem in Aspen. Estimate the Relative volatility between butanol and propanol using the heuristic formula. Compare the xy diagram generated based on the CRV assumption and the xy diagram generated from Aspen simulation.
b Using McCabeThiele method, determine the minimum number of stages at total reflux, the minimum reflux ratio, the number of equilibrium stages when the column is operated at above the minimum reflux, the feed stage location.
c Assuming a tray efficiency of and using all design heuristics, estimate the diameter and height of the column, as well as the pressure drop within the distillation column.
d Simulate the distillation process in Aspen HYSYS Report liquid composition profile within the column, temperature profile within the column, and reboiler and condenser heat duties.
