Title (EN) PROCESSES FOR CONDUCTING EQUILIBRIUM-LIMITED REACTIONS
(FR) PROCEDES POUR REALISER DES REACTIONS LIMITEES A L'ETAT D'EQUILIBRE
Abstract:
(EN) Processes for conducting equilibrium-limited reactions such as esterification and alcoholysis reactions, use two reaction zones. The first reaction zone operates under reaction conditions that retain at least a portion of the product in a liquid phase, and at least a portion of the liquid from the first reaction zone is introduced into a second reaction zone which operates under conditions such that at least a portion of the product produced in the second reaction zone is vaporized.
(FR) Les procédés faisant l'objet de cette invention, qui permettent de réaliser des réactions limitées à l'état d'équilibre, telles que des réactions d'estérification et d'alcoolyse, utilisent deux zones de réaction. La première zone de réaction agit dans des conditions de réaction qui retiennent au moins une partie du produit dans une phase liquide, et au moins une partie liquide provenant de la première zone de réaction est introduit dans une seconde zone de réaction, laquelle agit dans des conditions telles qu'au moins une partie du produit obtenu dans la seconde zone de réaction est vaporisée.
