Abstract
The present invention relates to a process and a system for producing alcohol by distillation with energy optimization using split-feed technology. The process of the present invention comprises the steps of: a) splitting a stream of wine to feed two depuration columns , the depuration column generating a stream of phlegma and the depuration column generating a stream of phlegma and a stream of vinasse; b) feeding the stream of phlegma into at least one rectification column generating a top flow and a stream of hydrated alcohol; c) effecting the heat exchange between the top flow from at least one rectification column and the stream of vinasse from the depuration column in at least one heat exchanger; and d) feeding the stream of phlegma into a rectification column generating a stream of hydrated alcohol. The present invention further relates to hydrated alcohol produced by the process described above and to a process for producing anhydrous alcohol.
