Amix of alcohol containing 53.3%wt methanol (m), 24.8%wt ethanol (e), 17.1%wt propanol (p), and 4.8%wt butanol (b) is being separated using two distillation columns. the mix is fed to the first distillation column at 32000 kg/h. the top product stream of this column contains only methanol and ethanol, and the bottom stream doesn't have any methanol. also, 98% of ethanol in the feed is recovered in the top product stream. a) find the composition of and flowrates of top and bottom product streams. b) find the flowrate of the reflux stream if reflux ratio1.5 (reflux ratio is the flowrate of the reflux stream divided by the flowrate of the top product)
