Consider the following bubble point feed stream with components A, B and C for separation by distillation using either a direct sequence or an indirect sequence, as shown below: A, B, C B B, C A, B, C A, B C A αk/c fk (gmol/s) A 5.5 30 B 2.0 40 C 1.0 30 B Direct Sequence Indirect Sequence Assuming an overall recovery of 95% for each component, calculate /answer the following for both sequences: a) Mass balance. b) Theoretical number of trays for all columns. c) Which sequence will be cheaper to operate and why. Hint: Does the selection of the single-column recoveries impact your answer? How?
