Abstract

The present invention relates to a system for producing ethanol from an organic source and that operates to purify and dry ethanol from a beer source. The system for producing substantially anhydrous ethanol comprises: (a) a first distillation stripping column; (b) a second distillation rectifying column having a higher operating temperature than said stripping column; (c) a molecular sieve dehydration means in fluid communication with said rectifying column. Heat from the overhead of the second distillation rectifying column and the molecular sieve dehydration are used to heat the first distillation stripping column.
