Build an Aspen flowsheet simulation of this problem. Use NRTL parameters for the VLE and determine the optimum reaction temperature this way. Find more appropriate conditions for the flash in S-401 that help optimize acetone recovery. Comment on the influence of non-ideality on the split in S-401. Use Aspen Capital Cost Estimator to give an estimate for the bare equipment cost of the S-401 flash. Your assignment is to obtain the optimum design conditions for the process as described, by carrying out the appropriate material balances. Here the optimum refers to a "gross profit," defined as: gross profit = value of products - cost of materials input (5) For this assignment the products of value are acetone. Do not take credit for any of the waste liquid streams. The materials input to the process are the aqueous IP solution and process water. The market prices for the aqueous IP solution and for the pure acetone may be found in The Chemical Marketing Reporter (CMP). (For the aqueous IP solution, use the value for the aqueous solution with IP concentration closest to 88 wt%.) The price for process water is $0.04/1000 kg
