2. 50 mol\% methanol - 50 mol\% water mixture is to be fractionated into a 96% methanol stream and a 96% water stream with a distillation column operating at an average pressure of 1atm. The feed mixture has a flowrate of 1000kmol/h and is in saturated liquid state. The column has a total condenser and a partial reboiler. The reflux ratio, the ratio of the flowrate of the reflux stream sent from the condenser to the top-most stage of the column to the distillate flowrate, is 1 . The reflux is a saturated liquid. Do not assume constant molal overflow, that is the next question. a) Calculate the distillate and bottoms product flowrates. b) What is the cooling duty in the condenser? Suggest a suitable cooling fluid for this duty. c) What is the heating duty in the reboiler? Suggest a suitable heating fluid for this duty. d) Calculate the following flowrates and compositions: V1,V2,V3,L0,L1,L2 (vapor and liquid flowrates) y1,y2,y3,x0,x1,x2 (vapor and liquid compositions) Enthalpy-composition data are available for methanol(A)-water(B) mixtures on the next page
