An aqueous solution of methanol containing 20% by weight methanol is fed to a distillation column. A vapor overhead product that is 97% by weight methanol and a liquid bottoms product that is 2% by weight methanol is obtained. The vapor overhead product is totally condensed and part of it is returned to the distillation column. The part of the condensed overhead product that is returned to the column is called the reflux and the part that is withdrawn from the process is called the distillate. The ratio of flow rate of the reflux to the distillate is 3.5. The feed flows at a rate of 100 kg/h. Calculate: a) the flow rate of the distillate and the bottoms product b) the ratio of the amount (in kg) of the vapor overhead product per kg of distillate c) the ratio of the amount (in kg) of the vapor overhead product per kg of feed

Question
An aqueous solution of methanol containing 20% by weight methanol is fed to a distillation column. A vapor overhead product that is 97% by weight methanol and a liquid bottoms product that is 2% by weight methanol is obtained. The vapor overhead product is totally condensed and part of it is returned to the distillation column. The part of the condensed overhead product that is returned to the column is called the reflux and the part that is withdrawn from the process is called the distillate. The ratio of flow rate of the reflux to the distillate is 3.5. The feed flows at a rate of 100 kg/h. Calculate: a) the flow rate of the distillate and the bottoms product b) the ratio of the amount (in kg) of the vapor overhead product per kg of distillate c) the ratio of the amount (in kg) of the vapor overhead product per kg of feed
