TRANSCRIPT

Using the enthalpy-composition diagram for the methanol-water system (Figure 1), calculate the number of stages required and the feed plate location to produce 98 wt% methanol liquid product and 5 wt% methanol bottoms product from a feed of 45 wt% methanol entering the column at 50oC. The column has a total condenser and a partial reboiler, and operates at 1.5 times minimum reflux. What is the reboiler duty in Btu/hr if the feed rate is 5,000 lb/hr? What is the condenser duty?
