Question

The distillation column shown at the right is used to separate compound A from compound B in an adiabatic fashion. A liquid mixture of A and B is fed at a specified temperature into a distillation column (stream 1). At the top of the column, a vapor stream that is A-rich (stream 2) passes through a condenser that completely condenses the mixture. Half of this liquid leaves the condenser as the overhead product (stream 4), and half of the liquid returns to the distillation column as reflux (stream 3). At the bottom of the column, a liquid stream that is B-rich is partially vaporized by a reboiler. The vapor from the reboiler (stream 5) returns to the distillation column while the liquid from the reboiler (stream 6) leaves the condenser as the bottoms product. The composition, temperature, and enthalpies for each stream component are given in the table below reflux overhead produc feed 0 bottoms product Stream State Temperature ("C) mol A/mol mol B/mol AB Liquid 65.0 2Vapor 70.0 Liquid 50.0 Liquid 50.0 5Vapor95.0 Liquid 95.0 0.520 0.960 0.960 0.960 0.410 0.130 0.480 0.040 0.040 0.040 0.590 0.870 452 431 7233 6513 0 7542 7196 6 Hint Previous 1375 1301 Give lin & Vho Sade at
