Question
A continues fractionation column, operation at atmospheric pressure, is to be
designed to separate a mixture containing 27% CS₂ and 73% CCl4 into an overhead product
containing 95% CS2 and a waste of 95% CCl4 (all mole percent). If the reflux ratio is taken as 3.16,
using the data below. Determine the number of plates required in the following cases: -
a- Feed inlet at T = 290 k
b- Feed inlet at T = 336 k
c- Feed inlet partially vaporized 70% liquid and 30% vapor.
d-Feed is saturated vapor and xf = 0.5.
e-Feed inlet at T = 380 k and xf = 0.5.
Given the following data:- cpr = 225.42 kJ/kmol.k, TB.p=336k, λ = 25900 kJ/kmol.
