mass transfer 100Kgmol/h of a bubble point liquid mixture of 75 mole% water (Mwt =18) and 25 mole % acetic acid (Mwt =60.5) is distilled
mass transfer
100Kgmol/h of a bubble point liquid mixture of 75 mole\% water (Mwt =18) and 25 mole \% acetic acid (Mwt =60.5) is distilled continuously in a distillation tower at a pressure of 1atm. Distillate contains 95mol% of light component and bottom 95 mole \% of heavy component. The reflux ratio is 2 times of minimum reflux ratio (R=2Rmis). a) Determine the amounts of distillate (D) and bottom product (B) in kgmol/hr. b) Determine the number of theoretical stages and optimum feed stage location. c) Determine the minimum number of stages graphically and using Fenske equation. d) Calculate the amount of steam required for heating the re-boiler if the steam pressure is 0.4Mpa ( H steam =2133.9kJ/kg ). e) Calculate the amount of cooling water required for the total condenser, the cooling water is preheated by 20C(CP cooling-water =4.184kJ/kgK). Equilibrium data water acetic acid at 1 atm (mole fractions) Heat of evaporation at Tw for water (hwatr)=2214kJ/kg Heat of evaporation at Tw for acetic acid (hmenicwid)=390kJ/kg Nm=log(aw)log(1xDxDxB1xB) Page 5 of 8 Rm+1Rm=xDxxDy Step by Step Solution
