Analyze an industrial process formed by a distillation column that is proposed for the separation of a ternary mixture composed of ethyl alcohol 61.9%, benzene 7% and the rest of water. The column has been designed to produce a distillate stream with 10% benzene and 88% ethanol. The column operates in such a way that the molar flow leaving the top of the column is recycled 50%.

The machine is designed to obtain 700 mol/h in the distillate stream. The bottom stream contains a negligible amount of benzene.Calculate the bottoms ethanol composition, the feed and bottoms stream molar flows.

Feed = _____ mol/h

Bottom stream = _____ mol/h

Ethanol composition = _____%
