Aliquid feed of 100kg mol/hr of benzene-toluene at the boiling point contains 55 mol% benzene and 45 mol% toluene. benzene is the more volatile component of the two. it is being distilled at 101.32kpa to give a distillate of composition 98mol% benzene and a residue product which is lean at 10mol%. using a reflux ratio of 2.0 do the following. a) determine top and bottom product flow rates b) determine the number of theoretical trays required c) calculate the condenser heat load d) calculate the reboiler heat load e) state how you would determine the minimum number of theoretical trays required
