Design a distillation column that will separate a feed of 100 kmol/h of 50 mol% water and 50 mol% methanol at 25C and 1.4 bar. It is desired to have a methanol fractional recovery of 95 % in the distillate and a water fractional recovery of 99% in the bottoms. Assume the condenser is total condenser operating at 1 bar. Using SRK as the property method, perform the following tasks: 1. Plot the XY equilibrium curve using the HYSYS. 2. Find the optimal design using shortcut methods tool of Aspen-HYSYS assuming a Reflux ratio, R, approximately equal to 1.6*Rmin 3. Using the results from the short-cut method, design and simulate the distillation column (rigorous model) to achieve the desired purities. 4. Study the effect of changing the fractional recovery of methanol in the distillate from 90 % to 99 % on the reboiler duty (kW) using the Case Studies tool. 5. Study the effect of changing the external reflux ratio on the actual number of trays required using the Case Studies tool? 6. Plot the vapor and liquid flowrate in the column. Briefly explain the trends. 7. Plot the temperature profile of the distillation column. What are the temperatures and duties of the condenser and reboiler in kW?
