Question
Transcribed Image Text:2.13. Condenser duty for two-liquid-phase distillate.
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 a process simulator to
compute the heat-transfer rate in Btu/h and kJ/h for the condenser.
