Abstract
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 kobs are 5.561 × 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.
