Abstract
(DE) Einbauten für Stoffaustauschkolonnen mit wenigstens einem Packungsbett (201; 301; 401). Das Packungsbett (201; 301; 401) weist mindestens einen ersten Packungsblock (208; 302; 402) und mindestens ein ihm zugeordnetes Korrekturelement (209; 303; 403) auf, wobei der Packungsblock (208; 302; 402) und sein zugeordnetes Korrekturelement (209; 303; 403) unterschiedliche Flüssigkeitsendverteilungen resp. systematische Maldistributionen erzeugen. Der Packungsblock (208; 302; 402) sowie sein zugeordnetes Korrekturelement (209; 303; 403) sind so angeordnet und ausgewählt, dass die durch den Packungsblock (208; 302; 402) verursachte systematische Maldistribution in der flüssigen Phase durch diejenige des zugeordneten Korrekturelementes (209; 303; 403) mindestens teilweise korrigiert wird. Bei Anwendungen in Stoffaustauschkolonnen werden mit dieser Packung erhöhte Trennleistungen erreicht resp. sind Packungsbetten mit grösserer Höhe möglich.
(EN) The invention relates to baffles for material exchange columns having at least one packing bed (201, 301, 401). The packing bed (201, 301, 401) has at least one first packing block (208, 302, 402) and at least one correction element (209, 303, 403) assigned thereto. The packing block (208, 302, 402) and its assigned correction element (209, 303, 403) produce different final distributions of liquid or systematic multiple distributions. The packing block (208, 302, 402) and its assigned correction element (209, 303, 403) are so fitted and selected that the systematic multiple distribution in the liquid phase caused by the packing block (208, 302, 402) is at least partially corrected by the systematic multiple distribution of the assigned correction element (209, 303, 403). The use of this packing in material exchange columns makes possible enhanced separation efficiency or higher packing beds.
(FR) L'invention concerne des chicanes pour colonnes d'échange de substance, comportant au moins un lit de garniture (201; 301; 401). Le lit de garniture (201; 301; 401) comporte au moins un premier bloc de garniture (208; 302; 402) et au moins un élément de correction (209; 303; 403) associé à ce bloc. Le bloc de garniture (208; 302; 402) et son élément de correction (209; 303; 403) associé produisent des répartitions finales de liquide ou des distributions multiples systématiques. Le bloc de garniture (208; 302; 402) ainsi que son élément de correction (209; 303; 403) associé sont disposés et sélectionnés de façon telle que la distribution multiple systématique en phase liquide produite à travers le bloc de garniture (208; 302; 402) est au moins partiellement corrigée par celle de l'élément de correction (209; 303; 403) associé. Lorsque l'on utilise ces chicanes dans des colonnes d'échange de substance, on peut obtenir avec cette garniture des puissances de séparation élevée ou bien l'on peut former des lits de garniture d'une hauteur plus importante.
