Described are preferred processes separating desired chemical products from other compounds in solution utilizing thermally-managed chromatography over solid adsorbents. The preferred processes involve chromatographic principles which are assisted by varying the temperature of operation in separation and elution phases. Also described are processes for treating aqueous acids to dewater and recover the acids in an organic solvent such as an alcohol.
L'invention concerne des procédés permettant de séparer les produits chimiques désirés d'autres composés contenus dans une solution à l'aide de la chromatographie thermiquement assistée sur adsorbants solides. Les procédés préférés font appel aux principes de la chromatographie, à laquelle s'ajoute la variation de la température de l'opération durant les phases de séparation et d'élution. L'invention concerne également des procédés permettant de traiter les acides aqueux afin de déshydrater et de récupérer les acides contenus dans un solvant organique tel qu'un alcool.
