Absorption of CO2 in DMAEE-DGA-DBU Aqueous Solution
Abstract
39 sets of solutions were compounded from 2-[2-(Dimethylamino)ethoxy]ethanol (DMAEE), 2-(2-Aminoethoxy)ethanol (DGA) and 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU). There solutions were tested relevant to the stirred reactor, at 303K~323K, 0.1MPa, to establish their absorption performance. An equation was utilized to model the absorption curve and the simulation results agreed well the experiments. The relevance of temperature and composition of solution with absorbed performance were revealed on the basis of comparison and analysis.
