Abstract
An acetone- benzene was selected to analyze the effect of feed vapor fraction on the total heat consumption in conventional distillation process. Heat consumption by distillation column (?Q) were evaluated by using the Aspen plus software, in order to determine the best economically state of feed. The work results are based on the lower consumption of energy at boiling point feed state. The operation cost of feed at saturated liquid(V.F=0) is reduction by (32.3%) than the cost of feed at saturated vapor (V.F=1). Keywords: Vapor fraction ,distillation , consumption energy.
