A liquid mixture containing 45.0wt% benzene (B) and 55.0% toluene (T) is fed to a distillation column operating at steady state. product streams emerge from the top and bottom of the column. the top product stream contains 95.0wt% B, and the bottom product stream contains 8% of the benzene fed to the column. the volumetric flow rate of the feed stream is 2000 liters/hr and the specific gravity of the feed mixture is 0.872. Required:
Determine the mass flow rate of the overhead stream and the mass flow rate and composition of the bottoms stream.
