ABSTRACT:
The present invention relates to a method for removing carbon dioxide (CO2) from a gas stream. Particularly, the present invention relates to a method for removing CO2from a gas stream by a liquid absorbent having an amino alcohol derived from 4-amino-2-butanol. In comparison to conventional amines, the amino alcohols of the present invention have been found to provide a higher CO2absorption capacity and a higher cyclic capacity for CO2removal.
