A Study of Mass Transfer Kinetics of Carbon Dioxide in (Monoethanolamine + Water) by Stirred Cell
Ying, Jiru; Eimer, Dag-Arne (Conference object; Journal article; Peer reviewed, 2013-08-05)The gas phase resistance in a stirred cell was investigated to understand and avoid its influence on the measurement of the reaction kinetics. To validate the influence of gas phase resistance and the experimental conditions ... -

Density, viscosity and free energy of activation for viscous flow of CO2 loaded 2-amino-2-methyl-1-propanol (AMP), monoethanol amine (MEA) and H2O mixtures
Karunarathne, Sumudu S.; Eimer, Dag-Arne; Øi, Lars Erik (Peer reviewed; Journal article, 2020)This work presents an experimental study of densities and viscosities of aqueous AMP (2-amino-2-methyl-1-propanol) + MEA (monoethanol amine) + H2O solutions with and without CO2. Amine concentrations were at AMP to MEA ... -
Density, viscosity and free energy of activation for viscous flow of monoethanol amine (1) + H2O (2) + CO2 (3) mixtures.
Karunarathne, Sumudu S.; Eimer, Dag-Arne; Øi, Lars Erik (Peer reviewed; Journal article, 2020)Densities and viscosities of aqueous monoethanol amine (MEA) and CO2-loaded aqueous MEA are highly relevant in engineering calculations to perform process design and simulations. Density and viscosity of the aqueous MEA ... -
Density, Viscosity, and Excess Properties of MDEA + H2O, DMEA + H2O, and DEEA + H2O Mixtures
Karunarathne, Sumudu S.; Eimer, Dag-Arne; Øi, Lars Erik (Peer reviewed; Journal article, 2020)This study presents measured density and viscosity of N-methyldiethanolamine (MDEA) + H2O, Dimethylethanolamine (DMEA) + H2O, and Diethylethanolamine (DEEA) + H2O mixtures. The density was measured at amine mass fraction ... -
Model uncertainty of interfacial area and mass transfer coefficients in absorption column packings
Karunarathne, Sumudu S.; Eimer, Dag-Arne; Øi, Lars Erik (Journal article; Peer reviewed, 2017)Uncertainty in model input parameters propagates through the model to make model output imprecision. Here, mathematical models used to calculate interfacial area and mass transfer coefficient for both random and structured ... -

The Activator Mechanism of Piperazine in Aqueous Methyldiethanolamine Solutions
Ying, Jiru; Raets, Stef; Eimer, Dag-Arne (Journal article; Peer reviewed, 2017)Piperazine (PZ) is added to aqueous methyldiethanolamine (MDEA) solutions to achieve a greater CO2 absorption in CO2 capture technology. It is referred to as “activated MDEA solutions” in the industry. However, does PZ ... -
