Question

A new manufacturer of ethanol denoted as EtOH, is having a bit of difficulty with a distillation column and thinks too much alcohol is lost in the bottoms (waste). The process is shown in Figure 1.

Calculate the composition of the bottoms stream based on the data shown in Figure 1.
If steam leaked into the column at 100 mol/sec and all else was constant, what would the new bottoms composition be?
