摘要：
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.
