Solve for the following problem. Determine the OMB and CB 3. 2000 kg/h of a mixture containing of 60 wt% benzene and 40 wt % toluene is to be separated in a distillation column. The distillate is to contain 98 wt% benzene and 95%, of feed benzene is to be recovered as distillate. What are the flow rates of the distillate and bottoms product and the composition of the bottoms product? 4. A product stream leaving the top of the column (the overhead product) containing 99.0 mole % B and a bottom product stream contains 80% of the benzene fed to the column (meaning that 92% of the benzene leaves with the overhead product.). The volumetric flow rate of the fed stream is 2000 L/h and the sp. gravity of the feed mixture is 0.872. Determine the mass flow rate of the overhead product stream and the mass flow rate and the composition (mass frac of the bottom product stream)
