Using the Peng-Robinson equations for thermodynamic properties, calculate the product compositions, stage temperatures, interstage vapor and liquid
Question:
Using the Peng-Robinson equations for thermodynamic properties, calculate the product compositions, stage temperatures, interstage vapor and liquid flow rates and compositions, reboiler duty, and condenser duty for the following multiple-feed distillation column, which has 30 equilibrium stages exclusive of a partial condenser a partial reboiler and operates at 250 psia. Feeds (both bubble-point liquids at 250 psia):Distillate rate = 36.0 lbmolhr.Reflux rate = 150.0 lbmol/hr.Determine whether the feed locations areoptimal.
