Example 3.6: A continues fractionation column, operation at atmospheric pressure , is to be
designed to separate a mixture containing 27% CS2 and 73% CC14 into an overhead product
containing 95% CS2 and a waste of 95% CC14 (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: -
1_Feed inlet at T = 290 k
2_Feed inlet at T = 336 k
3_Feed inlet partially vaporized 70% liquid and 30% vapor.
4_Feed is saturated vapor and xf = 0.5.
5_Feed inlet at T = 380 k and xf = 0.5.
Given the following data:- cpf = 225.42 kJ/kmol.k, TB.p = 336k , 2 = 25900 kJ/kmol .
