a A feed mixture consisting of 40% MethyEthylKetone and 60mol% water is fed to the low pressure column at 1 atm, and a molar flow rate of 100 kgmol/h. LP column: 10 stages, 5th feed stage, condenser and reboiler pressure as 1 atm, 99% recovery of MEK, and 69mol% MET in the top of the LP column. Pump: the top product of LP column is pumped to high pressure column at 100 psia. HP column: 15 stages, 7th feed stage, condenser and reboiler pressure as 100 psia, 90 mol% MEK in the bottom product flow rate as 40 kgmole/hr. recycle stream with the following specifications: (vapor fraction = 0; pressure = 1 atm; flow rate = 36 kgmol/hr, 55mol% MEK, and 45mol% water. Estimate the separation achieved Low 15 psia , and high 100 psia. Property package: Wilson and Activity model specifications: RK
