Abstract: Verfahren zum Entfernen saurer Gase aus einem unter Gasströmen ausgewählten Fluidstrom, bei dem mana) den Fluidstrom im Kontakt mit einem Absorptionsmittel, das eine wässrige Lösung wenigstens eines Amins umfasst, durch eine erste Absorptionszone in einem Absorber leitet, wobei man eine Hauptmenge der sauren Gase entfernt, und den Fluidstrom durch eine zweite Absorptionszone in dem Absorber leitet, wobei man eine weitere Menge der sauren Gase entfernt,b) das beladene Absorptionsmittel in eine erste Regenerationszone leitet, wobei man ein teilregeneriertes Absorptionsmittel erhält, und einen Teil des teilregenerierten Absorptionsmittels in die erste Absorptionszone leitet,c) den anderen Teil des teilregenerierten Absorptionsmittels in eine zweite Regenerationszone leitet, wobei man ein regeneriertes Absorptionsmittel erhält, wobei die erste Regenerationszone oberhalb der zweiten Regenerationszone in einer Kolonne angeordnet ist, die erste Regenerationszone durch aufsteigende Brüden aus der zweiten Regenerationszone beheizt wird und das von der ersten Regenerationszone in die zweite Regenerationszone geleitete teilregenerierte Absorptionsmittel durch indirekten Wärmetausch mit dem aus der zweiten Regenerationszone austretenden regenerierten Absorptionsmittel vorerwärmt wird, undd) einen Teil des regenerierten Absorptionsmittels in die erste Absorptionszone und den anderen Teil des regenerierten Absorptionsmittels in die zweite Absorptionszone leitet.

Abstract: The invention relates to a method for producing EDDN and/or EDMN by reacting FA HCN and EDA the reaction being carried out in the presence of water and separating the water from the reaction mixture in a distillation column after the reaction characterized in that distillation is carried out in the presence of an organic solvent which at the distillation pressure prevailing in the column has a boiling point between that of water and EDDN and/or EDMN or which forms a low boiling azeotrope with water.

Abstract: The invention relates to a process for preparing an ethylene amine mixture, which comprises hydrogenating an amino nitrile mixture comprising at least 30% by weight of aminoacetonitrile (AAN) and at least 5% by weight of iminodiacetonitrile (IDAN) in the presence of a catalyst. Ethylenediamine (EDA) and/or diethylenetriamine (DETA) and, if appropriate, further ethylene amines can be isolated from the ethylene amine mixtures obtained.

Abstract: In a method for removing acid gases from a fluid stream, the fluid stream, which is in contact with an absorption medium within an absorber, is passed through a first absorption zone in the absorber to remove a majority of acid gases from the fluid stream. The fluid stream is susequently passed through a second absorption zone in the absorber to further remove acid gases from the fluid stream. The loaded absorption medium is passed into a first regeneration zone to obtain a partially regenerated absorption medium, and a part of the partially regenerated absorption medium is passed into the first absorption zone. The other part of the partially regenerated absorption medium is passed into a second regeneration zone to obtain a regenerated absorption medium. A part of the regenerated absorption medium is passed into the first absorption zone and the other part is passed into the second absorption zone.
