Question:
A mixture of ethylbenzene and xy lenes is to be distilled as shown in figure 9.29. Assuming the applicability of Raoult's and Dalton's laws:
(a) Use the Fenske-Underwood-Gilliland method to estimate the number of stages required for a reflux-to-minimum reflux ratio of 1.10. Estimate the feed stage location by the Kirkbride equation.
(b) From the results of part (a) for reflux, stages, and distillate rate, use the Edmister group method of Section 5.4 to predict the compositions of the distillate and bottoms. Compare the results with the specifications.
