For the separation of A and B, a distillate of 98% purity A and bottoms of 96% B is desired. (a) Use McCabe Thiele to determine the minimum number of stages given the VLE below if a total condenser and partial reboiler is used (b) In this analysis is only maters that the feed has a purity between 98%A and 98% B. Explain why the feed composition and condition otherwise does not matter for this analysis 1 0.9 0.8 0.7 0.6 20.5 0.4 0.3 0.2 0.1 0 o 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1 x X A
