Abstract
The present disclosure provides processes and systems for ethanol production. In one embodiment, a first beer column receives a first portion of a feed mixture including ethanol and water to form a first beer column bottom stream and a first beer column vaporous overhead stream. A beer column receives a second portion of the feed mixture. A first portion of the first beer column bottom stream is forwarded to a first beer column reboiler. A second portion of the first beer column bottom stream is forwarded to a plurality of evaporators. A condensed portion of the first beer column vaporous overhead stream is forwarded to a stripper column. The stripper column forms a feed stream, which is contacted with a separation system, thereby forming a permeate and a retentate. The permeate is forwarded directly to at least one selected from the first beer column and the stripper column.
