Abstract
(EN) The present invention refers to an apparatus and process for distillation of methanol (Fig. 1), however may also be used in distillation of other products such as ethanol. The present invention has the purpose of reducing the consumption of energy and of cooling water and/or electricity in a distillation process of crude intermediate products, comprising a pre-treatment stage, known as stabilizing stage, for the removal of the volatile components, and a concentration stage, comprising one or more columns for distillation.
