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 col- umn 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.
