Title
(DE) VORRICHTUNG ZUR ENTFERNUNG VON AMMONIAK ODER AMINEN AUS REAKTIONSLÖSUNGEN
(EN) DEVICE FOR REMOVING AMMONIA OR AMINES FROM REACTION SOLUTIONS
(FR) DISPOSITIF POUR ELIMINER DE L'AMMONIAC ET DES AMINES DE SOLUTIONS DE REACTION
Abstract
(DE) Es wird eine Vorrichtung zur Entfernung von Ammoniak oder flüchtigen Aminen aus einer Reaktionslösung beschrieben, die einen Rührreaktor (1) aufweist, der über eine Saugleitung (Steigleitung) (2) mit einer in einem Sprühreaktor (3) angebrachten Düse oder einem Sprühkopf (4) verbunden ist, in dem der Ammoniak oder das flüchtige Amin freigesetzt wird, welches durch einen Stickstoffstrom (5) oder durch angelegten Unterdruck von der Reaktionslösung abgetrennt und aus dem System entfernt wird.
(EN) The invention relates to a device for removing ammonia or volatile amines from a reaction solution. Said device comprises an agitator reactor (1), which is connected to a nozzle or a spray head (4), which are arranged in a spray reactor (3) by means of a suction line (ascending line) (2), wherein the ammonia or the volatile amine is released which is separated from the reaction solution by means of a nitrogen flow (5) or by a negative pressure and is removed from the system.
(FR) L'invention concerne un dispositif pour éliminer l'ammoniac ou les amines volatiles provenant d'une solution de réaction, qui présente un réacteur de malaxage (1), lequel est relié par un canal d'aspiration (2) (conduite ascendante) à une buse ou une tête d'aspersion (4) disposées dans un réacteur d'aspersion (3), dans lequel l'ammoniac ou l'amine volatile est libéré, lesquels sont séparés par un flux d'azote (5) ou par une dépression appliquée à la solution de réaction, puis sont éliminés du système.
