COMBINED, THE MOLECULAR SIEVE-ALCOHOL SALT DISTILLATIONS, BIOETHANOL DEHYDRATATION METHOD

摘要

In the bio-ethanol dehydration process, that contains alcohol distillation stage, concentration by rectifying and treatment in molecular sieves, it is possible to economize a part of outlay energy by fully or partly replacing rectification stage with alcohol-salt distillation stage that is energetically advantageous as rectification and enables to obtain alcohol of a higher concentration.
