Title
(EN) PROCESS FOR THE PRODUCTION OF METHANOL FROM WASTE GAS
(FR) PROCEDE D'ELABORATION DE METHANOL A PARTIR D'EFFLUENTS GAZEUX
Abstract
(EN)
Methanol is economically produced from carbon dioxide in a high yield by a process which comprises compressing a gaseous mixture of carbon dioxide and hydrogen; introducing the compressed gaseous mixture into a conversion column; converting a part of the carbon dioxide contained in the mixture to carbon monoxide in the presence of a catalyst in the conversion column to produce a gas phase mixture and a liquid phase mixture; removing the liquid phase mixture in a gas-liquid separator; introducing the gas phase mixture from the gas-liquid separator into a reactor while recycling, optionally, a part thereof into the conversion column; reacting the compressed gas phase mixture introduced into the reactor in the presence of a catalyst to produce a mixture containing methanol; and recovering methanol as a liquid phase product from the mixture.

Procédé permettant de produire de manière économique et avec un rendement élevé du méthanol à partir du dioxide de carbone. Ce procédé consiste à comprimer un mélange gazeux de dioxide de carbone et d'hydrogène; à introduire ce mélange gazeux comprimé dans une colonne de conversion; à convertir une partie du dioxide de carbone contenu dans le mélange en monoxide de carbone en présence d'un catalyseur, dans la colonne de conversion, pour obtenir un mélange en phase gazeuse et un mélange en phase liquide; à extraire le mélange en phase liquide dans un séparateur gaz/liquide; à introduire le mélange en phase gazeuse du séparateur gaz/liquide dans un réacteur tout en recyclant, éventuellement, une partie de ce mélange dans la colonne de conversion; à faire réagir le mélange en phase gazeuse comprimé introduit dans le réacteur en présence d'un catalyseur pour produire un mélange contenant du méthanol; et à récupérer le méthanol sous forme de produit en phase liquide du mélange.
