2) Number of Ideal Stages for a Hydrocarbon Distillation A four component mixture of ethylbenzene (zı=0.06, ai=1.25), p-xylene (z2=0.40, a2=1.15), 0-xylene (z3=0.30, a3=1.00) and cumene (z4=0.24,...

Extracted text: 2) Number of Ideal Stages for a Hydrocarbon Distillation A four component mixture of ethylbenzene (zı=0.06, ai=1.25), p-xylene (z2=0.40, a2=1.15), 0-xylene (z3=0.30, a3=1.00) and cumene (z4=0.24, a4=0.68) is at its bubble point and enters a column at 80 kmole/hr. We would like to recover 99% of the p-xylene in the distillate and 96% of the o-xylene in the bottoms product. a) Determine the minimum number of stages, Fenske Nmin. b) Determine Rmin from Underwood assuming the relative volatilities provided. c) Determine the ideal number of stages required if a reflux ratio of three times the minimum is used. d) Determine N, R values using Gilliland, et al. How do the number of stages compare?
