Abstract

Abstract In the paper the results of measurements of CO2 absorption rate in aqueous potassium carbonate solutions containing cyclohexylamine, diethanolamine, 2-methylaminoethanol and triethylenetetramine as activators have been presented. Enhnancement mass transfer factors as well as reaction rate constants have been determined. Results show that among the tested activators triethylenetetramine and 2-methyl-aminoethanol may be used (instead of diethanolamine) as new promotors in a modified BENFLIELD process.
