2) In the Keyes process for making absolute alcohol from alcohol containing 5 wt% H20, a third component (CH) is added with the alcohol feed to produce a ternary azeotrope whose composition is: 18.5 wt% C,H,OH, 7.4 wt% H20 and 74.1 wt% CH. A single fractioning column is used to produce azeotrope as overhead and absolute alcohol as bottoms. What volume of benzene must be added to enable production of 4 m? of absolute alcohol? (2.185 m?) Data: 100 wt% ethanol 100 wt% benzene p=0.785 kg/L p=0.872 kg/L
