FIELD: process engineering.
SUBSTANCE: invention relates to absorbent intended for removing carbon dioxide from flue gases formed in incinerator running on fossil fuel. Absorbent contains two-component mix of free amino acid and amino acid salt. In terms of molar concentration, free acid occurs in the mix in excess amount as compared with amino acid salt. This allows well-directed variable pkB-index which may be reached at different temperatures of absorption and desorption.
EFFECT: absorbent notably improving energy balance.
