2) A liquid mixture of benzene-toluene is to be distilled in a fractionating tower at 1 atmosphere of pressure. The feed of 100kg/mol is liquid and it contains 45% mole and 55% mole toluene. The feed enters to boiling temperature. A distillated containing 95% mole benzene and bottom containing 10% mole benzene are obtained. The Cp of feed is 200KJ/KgmolK and the latent heat is 30000KJ/kg.mol. (12 pts.) Determine: a) Draw the equilibrium data with the table of the annexes. +2 b) The fi () factor. c) The minimum reflux. d) The operating reflux. 1.56+0,5 e) The number of trays f) Boiling temperature in the feed
