Distillation tower, 40 trays (reboiler and condenser), used to distill 100 lb/hr of crude oil. The crude oil has a temperature of 250°F and a pressure of 23 psi, and it enters the distillation column at tray number 20. This tower has two side-line outlets: one at plate 10, for liquid with a flow rate of 8.8 lb/hr, and another at plate 30, also for liquid with a flow rate of 44 lb/hr. The reflux ratio of the tower is 2, the flow rate at the bottom of the tower is 32.5 lb/hr, the operating pressure of the tower is 23 psi, and the RK-soave equation is used. The specific gravity of the crude oil is API=22.3. The mass percentage of fractions: F 15.2, 350; 23.5, 450; 67.5, 650; 100, 723. I can’t calculate it no matter what; please help me out, guys.
