Kinetics Study of CO_2 Absorption into Solutions of UDS

摘要

CO_2 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-LT~(-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 × 10~(-6) kmol-m~(-2)-sec~(-1) and 4,183.372 sec~(-1), respectively. The absorption activation energy of CO_2 into UDS is 44.92 kJ-mol~(-1).
