A 100lbmol/hr equimolar mixture of benzene and toluene is to be separated by distillation to produce a product containing 90 mols benzene and a 89% mole\% toluene. The feed to column is a saturated liquid at 92C and at 1.2atm. Use the DSTWU model with partial condenser and reflux ratio of 3 . The distillation column is to operate at 1atm pressure with a pressure drop of 0.2 atm. Use the Peng-Robinson model to estimate: a. The minimum reflux ratio and the minimum number of stages to accomplish the b. The actual number of stages and the location of the feed stage if the column is operated separation. at 1.2 times the minimum reflux ratio
