  • AQUEOUS CO2 ABSORBENT COMPRISING 2-AMINO-2-METHYL-1-PROPANOL AND 3-AMINOPROPANOL OR 2-AMINO-2-METHYL-1-PROPANOL AND 4-AMINOBUTANOL
    Publication number: 20230321589
    Abstract: An aqueous CO2 absorbent comprising a combination of 2-amino-2-methyl-1-propanol (AMP) and 3-aminopropanol (AP), or AMP and 4-aminobutanol (AB), is described. A method for capturing CO2 from a CO2 containing gas using the mentioned absorbent, and the use of a combination of AMP and AP, or a combination of AMP and AB are also described.

  • Absorbent system and method for capturing CO from a gas stream
    Patent number: 10413860
    Abstract: The present invention relates to an absorbent, an absorbent system and a process for removing acidic gas such as CO2 from exhaust gases from fossil fuel fired power stations, from natural gas streams, from blast furnace oven off-gases in iron/steel plants, from cement plant exhaust gas and from reformer gases containing CO2 in mixtures with H2S and COS. The liquid absorbent, a mixture of amine and amino acid salt is contacted with a CO2 containing gas in an absorber and CO2 in the gas stream is absorbed into the liquid. The absorbed CO2 forms more than one type of solid precipitate in the liquid at different absorption stages. In a first absorption stage solid precipitate of amine bicarbonate is formed and is withdrawn as slurry from the bottom of a first absorber section. In a second absorption stage solid precipitate of alkali metal bicarbonate is formed and withdrawn as slurry at the bottom of a second absorber section.
