The Improved Econamine technology uses an aqueous solution of DIGLYCOLAMINE® (DGA®). Solution concentrations of up to 65% weight DGA result in appreciably lower circulation rates and steam consumption when compared to other amines. The advantages of this technology include amine plant construction where stringent gas specifications must be met but cooling water is not available, operation in arctic climates where winterization is an issue, CO2 removal, H2S removal, and over 90% COS removal.
