Question

Selection of a separation sequence using
heuristics.
A distillation sequence produces the same four final products from the same five components in Figure 1.9. The molar percentages in the feed are C₃(5.0%), iC₄ (15%), nC₄ (25%), iC₅ (20%), and nC₅(35%). The most difficult separation by far is that between the isomers, iC₄ and nC₄. Use the heuristics to determine the best sequence(s). All products are to be of high purity.
