AIChE Journal, 2017, 63(7): 2694-2704.In this present work, the CO2 absorption performance of aqueous 1-diethylamino-2-propanol (1DEA2P) solution was studied with respect to CO2 equilibrium solubility, absorption kinetics, and absorption heat. The equilibrium solubility of CO2 in 2M 1DEA2P solution was measured over the temperature range from 298 to 333 K and CO2 partial pressure range from 8 to 101 kPa. The absorption kinetics data were developed and analyzed using the base-catalyzed hydration mechanism and artificial neural network models (radial basis function neural network [RBFNN] and back-propagation neural network [BPNN] models) with an acceptable absolute average deviation of 10% for base-catalyzed hydration mechanism, 2.

AIChE Journal, 63: 4465–4475, 2017In this work, the equilibrium solubility of CO2 in a 1-diethylamino-2-propanol (1DEA2P) solution was determined as a function of 1DEA2P concentration (over the range of 1–2 M), temperature (in the range of 298–333 K), and CO2 partial pressure (in the range of 8–101 kPa). These experimental results were used to fit the present correlation for K2 (Kent-Eisenberg model, Austgen model, and Li-Shen model). Read More
