An aqueous absorption medium for removal of acid gases from a gaseous stream includes at least one tertiary alkanolamine and at least one secondary alkanolamine. A total weight of the at least one tertiary alkanolamine and the at least one secondary alkanolamine account for an amine weight of the aqueous absorption medium. The amine weight of the aqueous absorption medium is from 25 wt % to 65 wt %, based on a total weight of the aqueous absorption medium, and the at least one secondary alkanolamine is present in an amount from 11 wt % to 45 wt %, based on the amine weight of the aqueous absorption medium.
