Isopropanol, with 13 wt% water, can be dehydrated to obtain almost pure isopropanol at a 90% recovery
Question:
Isopropanol, with 13 wt% water, can be dehydrated to obtain almost pure isopropanol at a 90% recovery by azeotropic distillation with benzene. When condensed, the overhead vapor from the column forms two immiscible liquid phases. Use Table 2.4 with data in Perry’s Handbook and the data below to compute the heat-transfer rate in Btu/h and kJ/h for the condenser.
