Abstract: An apparatus and process for distillation of methanol which may also be used in distillation of other products, such as ethanol. The apparatus and process have the purpose of reducing the consumption of energy and of cooling water and/or electricity in a distillation process of crude intermediate products, including a pre-treatment stage, known as stabilizing stage, for the removal of the volatile components, and a concentration stage, including one or more columns for distillation.
