6. (15) A distillation column is used as a propane-propylene splitter. The diagram to the right shows an operation example of such splitter where C3 refers to propylene and C3 refers to propane. Determine if the material balances are satisfactory. The distillation operation is targeted for a top stream at a C3 concentration better than 99.7wt% and a C3 " recovery better than 95%. Accordingly, analyze the expected effluents (top and bottom) conditions based on the given feed
