Publication number: 20220410028Abstract: The present disclosure provides processes and systems for heat integration in ethanol production. In one embodiment, a feed mixture is distilled with one or more distillation units to remove at least a portion of the water, and form a distillation unit bottom stream, a vaporous overhead stream, and a fusel oil stream. Molecular sieve units are regenerated by vacuum or a combination of vacuum and optionally a portion of the product stream to form one or more regenerate streams. A feed tank is configured to receive at least one selected from a condensed portion of the regenerate streams and a portion of a vaporous depressure stream, to form a feed stream. The energy contained in the depressure vapor is recovered by the depressure vapor contacting the feed tank and heating up at least one stream forwarded into the feed tank.Type: ApplicationFiled: August 29, 2022Publication date: December 29, 2022Applicant: Whitefox Technologies LimitedInventors: Virginia ANDRADE, Jin Ming ZHOU, Stephan Rüdiger BLUM

Patent number: 11007452Abstract: The present disclosure provides processes and systems for dehydrating a byproduct stream in ethanol production. In one embodiment, a feed mixture is distilled with one or more distillation units to remove at least a portion of the water, and form a first byproduct stream. The first byproduct stream is contacted with a molecular sieve unit, thereby forming a product stream. The molecular sieve unit is cyclically contacted with at least a portion of the product stream to regenerate the molecular sieve unit and form one or more regenerate streams. A second byproduct stream including at least one of (1) the regenerate streams and (2) at least a portion of the fusel oil stream is contacted with a separation system, thereby forming a permeate and a retentate. At least a portion of the retentate is forwarded into the product stream.Type: GrantFiled: November 25, 2019Date of Patent: May 18, 2021Assignee: WHITEFOX TECHNOLOGIES LIMITEDInventors: Stephan Rüdiger Blum, Virginia Andrade
