Definitions
- an amino acid salt having a carbon substituent selected from the group consisting of hydrogen, an alkyl, a hydroxyalkyl and an aminoalkyl More preferably, an amino acid salt having a nitrogen substituent selected from the group consisting of hydrogen, an alkyl, a hydroxyalkyl and a haloalkyl is used.
- a single amino acid salt such as a potassium salt of glycine or other amino acids may be employed.
- mixtures of different amino acid salts can be used as the absorbent.
- the amino acid salt is a salt of a metal, in particular an alkali metal.
- a regeneration stage for the washing medium is included with a number of reclaimers.
- decomposition products and non-regenerable reaction products are separated from the washing medium. This can be done, for example, by means of a distillation in which the washing medium condensed after the removal of the interfering components is again supplied to the washing device.
- the reclaimer serve here by regenerating the washing medium of targeted Störstoffausschleusung as well as the extraction of usable products from the flue gas.
- the regeneration stage or the or each reclaimer of the regeneration stage can be fluidly connected to a desorber.
- the washing medium purified after the desorption of carbon dioxide can be regenerated in the regeneration stage.
- Washing medium passes through a heat exchanger.
- the heat exchanger the heat of the regenerated scrubbing medium flowing from the desorber to the absorber is transferred to the laden scrubbing medium flowing out of the absorber.
- the heat exchanger thus utilizes the waste heat in the return line of the desorber to preheat the wash medium from the absorber prior to entering the desorber.
- the separation of the carbon dioxide from the washing medium usually thermally.
- the desorber of the separator is fluidly connected via a return line to a supply line of the absorber. So that can be done in the
- FIG 3 shows a column as part of a further apparatus for treating a flue gas with an absorber of a Separator for carbon dioxide and a pre-scrubber of a washing device.
- FIG. 1 Another difference from FIG. 1 lies in the fact that the return line 145 of the desorber 135 has no branch line. line for fluidic coupling with the washer 83 is connected. This is therefore a separate mode of operation of the first process stage (pre-cleaning) and the second process stage (C0 2 separation).

Abstract
L'invention concerne un dispositif (1) destiné à la préparation d'un flux de gaz, en particulier d'un flux de gaz de fumées, lequel dispositif comprend un dispositif de lavage (3) servant à éliminer les polluants contenus dans le flux de gaz au moyen d'un milieu de lavage (11), ainsi qu'un dispositif de séparation (5), placé en aval du dispositif de lavage (3), qui comprend un absorbeur (39) et un désorbeur (45) permettant de séparer le dioxyde de carbone contenu dans le flux de gaz au moyen d'un milieu de lavage (11). Le dispositif de lavage (3) et le dispositif de séparation (5) sont conçus pour permettre l'utilisation du même milieu de lavage (11). L'invention concerne en outre un procédé selon lequel le même milieu de lavage est utilisé aussi bien pour la pré-épuration du flux de gaz dans un dispositif de lavage (3) que pour la séparation du dioxyde de carbone dans un dispositif de séparation (5).
