Kinetics study of Co 2 absorption into solutions of UDS

CO2 absorption kinetics in united-developed desulfur solvent (UDS; a multicomponent solvent) and methyldiethanolamine solutions are measured in a disk column under the temperature range from 303 to 323 K and solution concentrations range from 0.35 to 4.371 mol . L-1. Under the condition of UDS concentration of 50% (4.371 mol . L-1) and temperature of 313 K, N and k(obs) are 5.561 x 10(-6) kmol . m(-2) . sec(-1) and 4,183.372 sec(-1), respectively. The absorption activation energy of CO2 into UDS is 44.92 kJ . mol(-1).
