In ICM’s integrated distillation, dehydration and evaporation (DDE) system, each process reuses energy to increase overall plant efficiency. Separation of ethanol and water by extractive distillation with salt and solvent as entrainer: process simulation. At the Middle of Cycle, the MTZ has moved about half way down the bed. At the top of the bed, where ethanol and water enter the unit, water has fully sat… The distillation process is powered by process vapors generated from the evaporation system. Extractive distillation can be used to achieve high purity of ethanol at low energy consumption and under simple operating conditions. ► Energy savings in the hybrid process is a function of the ethanol–water feed composition.
