Liquid phase mass transfer coefficients were measured for the absorption of carbon dioxide into water in concurrent flow. Liquid flow rates ranged up to 300 kg‐mol/min. m 2 or about 60,000 lb./hr. ft. 2 . In comparison with countercurrent flow, the coefficients were lower by as much as a factor of 3 with significant gas rate effect. Correlations for concurrent coefficients with liquid and gas flow rates were obtained in the form k x a = CL r G s for 19.0‐mm Berl saddles and 6.35‐mm and 12.7‐mm Rashig rings.
