摘要： A process for producing ethanol by evaporative distillation is disclosed, wherein fermented wash is first evaporated in an evaporator to generate a concentrated ethanol stream. The remaining part of said wash is then further purified in a mash column to isolate remaining ethanol from said wash. In this process as a large part of fermented wash is removed in evaporation process, the load on the mash column is significantly less and hence small size of mash column is required.
