Title (EN) RECOVERY OF SULPHURIC ACID
(FR) RECUPERATION D'ACIDE SULFURIQUE
Abstract: front page image
(EN)The invention is directed to a process for the recovery of sulphuric acid from a mixture comprising sulphuric acid and hydrocarbons, in particular carbohydrates. In accordance with the present invention the mixture comprising sulphuric acid and carbohydrates, is contacted with an anion selective membrane, thus producing a sulphuric acid rich filtrate stream and a stream depleted in sulphuric acid.
(FR)La présente invention porte sur un procédé de récupération d'acide sulfurique à partir d'un mélange comprenant de l'acide sulfurique et des hydrocarbures, en particulier des hydrates de carbone. Selon la présente invention, le mélange comprenant de l'acide sulfurique et des hydrates de carbone est mis en contact avec une membrane perméable aux anions, ce qui produit un flux de filtrat riche en acide sulfurique et un flux pauvre en acide sulfurique.
