Title
(EN) PROCESS AND APPARATUS FOR DISTILLATION
(FR) PROCÉDÉ ET APPAREIL DE DISTILLATION
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 pretreatment stage, known as stabilizing stage, for the removal of the volatile components, and a concentration stage, comprising one or more columns for distillation.
(FR) La présente invention concerne un appareil et un procédé de distillation de méthanol (Fig. 1), pouvant cependant également être utilisés pour la distillation d'autres produits tels que l'éthanol. La présente invention a pour objet de réduire la consommation d'énergie et d'eau de refroidissement et/ou d'électricité dans un procédé de distillation de produits intermédiaires bruts, comprenant une étape de prétraitement, dite étape de stabilisation, pour l'élimination des composants volatils, et une étape de concentration, comprenant une ou plusieurs colonnes de distillation.
