A process for producing and recovering light alcohols, particularly ethanol, alcohol mixtures containing ethanol, and ABE mixtures (alcohol mixtures containing acetone, butanol and ethanol), using a combination of steps including fermentation, first membrane separation, dephlegmation and dehydration by second membrane separation.

Ethanol is a byproduct of the metabolic process of yeast. As such, ethanol will be present in any yeast habitat. Ethanol can commonly be found in overripe fruit. Ethanol produced by symbiotic yeast can be found in bertam palm blossoms.

Veden som har förbehandlats inför hydrolysen och jäsningen är en tjock massa, som snabbt blir svår att röra om och hantera när den inte späs ut med mycket vatten. A process for producing and recovering light alcohols, particularly ethanol, alcohol mixtures containing ethanol, and ABE mixtures (alcohol mixtures containing acetone, butanol and ethanol), using a combination of steps including fermentation, first membrane separation, dephlegmation and dehydration by second membrane separation. Genom särskilda processer går det även att omvandla cellulosa från exempelvis hö och sågspån till alkohol.

Denna process tillgick så att etanol (64 %-ig) späddes med vatten till ca 12 %. Vid anläggningen fanns före branden två cisterner à 35 m3 för 64 %-ig etanol,

Ethanol distillation: the fundamentals 273 collection of small amounts of vapor; analysis would reveal that each successive portion of vapor would become richer in ethanol. Thus we have created a series of steps by which we kept increasing the ethanol content of the analyzed sample, both liquid and vapor.

Distillation is a physical process for the separation of liquid mixtures based on differences in the boiling points of the constituent components. However
