Abstract: A description is given of an absorption medium for removing carbon dioxide from a gas stream, which comprises an aqueous solution of at least one amine and at least one aminocarboxylic acid and/or aminosulfonic acid. The concomitant use of an aminocarboxylic acid or aminosulfonic acid reduces the energy required for regeneration of the absorption medium.

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.

Abstract: Disclosed is an absorbent for eliminating carbon dioxide from a gas flow. Said absorbent comprises an aqueous solution of at least one amine and at l east one amino carboxylic acid and/or amino sulfonic acid. Additionally usin g an amino carboxylic acid or amino sulfonic acid reduces the amount of ener gy required for regenerating the absorbent.

Abstract: A process for removing acid gases from a hydrocarbonaceous fluid stream or an oxygen-comprising fluid stream in which the fluid stream is contacted with an aqueous solution which is essentially free from inorganic basic salts and comprises (i) at least one amine and (ii) at least one metal salt of an aminocarboxylic acid and/or an aminosulfonic acid. Conjoint use of the aminocarboxylic and/or aminosulfonic salt reduces the coabsorption of hydrocarbons or oxygen without significantly impairing the absorption rate at which acid gases are absorbed, without significantly reducing the absorption capacity of the solution for acid gases, and without significantly increasing the energy demand required for regeneration.

Abstract: The present invention relates to an apparatus for the tangential introduction of a gas-loaded liquid stream into the top of a column in which gas and liquid are separated. Entry into the column top proceeds through a conventional radially arranged port, to which, however, a special tube construction connects which ensures as smooth as possible non-turbulent flow and its tangential exit into the column top.

Abstract: An absorbent for removing acidic gases from a fluid stream, comprising an aqueous solution a) of at least one metal salt of an amino carboxylic acid and b) of at least one acidic promoter, where the molar ratio of b) to a) is in the range from 0.0005 to 1Ø The acidic promoter is selected from mineral acids, carboxylic acids, sulfonic acids, organic phosphonic acids and partial esters thereof. The absorbent exhibits, compared to absorbents based on amino acid salts, a reduced requirement for regeneration energy, without significantly reducing the absorption capacity of the solution for acidic gases. In a process for removing acidic gases from a fluid stream, the fluid stream is contacted with the absorbent.

IPC: B01D53/14
Abstract: The invention relates to an absorbent, comprising an aqueous solution (A) of at least one amino acid salt of the formula (I), wherein R1 and R2 independently from each other represent alkyl or hydroxyalkyl, R is hydrogen, alkyl or hydroxyalkyl, or a group R together with R1 is alkylene, M is an alkali metal, and n an integer from 1 to 6, and (B) of at least one primary alkanolamine, which is substantially free of inorganic alkaline salts. The absorbent is used in a method for removing carbon dioxide from a gas flow, particularly combustion exhaust gases. Preferred amino acid salts (A) are N,N-dimethylamino acetic acid potassium salt, N,N-diethylamino acetic acid potassium salt and N-ethyl-N-methylamino acetic acid-potassium salt. Preferred alkanolamines (B) are 2-aminoethanol, 3-aminopropanol, 4-aminobutanol, 2-aminobutanol, 5-aminopentanol, 2-aminopentanol and 2-(2-aminoethoxy)ethanol.

Abstract: Method for the removal of acid gases from a fluid flow containing hydrocarbons or from a fluid flow containing oxygen, by means of bringing the fluid flow in contact with an aqueous solution, which is substantially free of inorganic alkaline salts and which contains (i) at least one amine and (ii) at least one metal salt of an amino acid and/or of a sulfur amino acid. The combined use of amino acid salt and/or sulfur amino acid salt reduces the coabsorption of carbohydrates and respectively oxygen, without substantially affecting the absorption velocity with which the acid gases are absorbed, without substantially reducing the absorption capacity of the solution for acid gases and without substantially raising the consumption of energy necessary for regeneration.
