Aqueous Mapa, DEEA, and Their Blend as CO2 Absorbents: Interrelationship between NMR Speciation, pH, and Heat of Absorption Data
Perinu, Cristina; Bernhardsen, Ida; Pinto, Diego Di Domenico; Knuutila, Hanna K; Jens, Klaus-Joachim (Journal article; Peer reviewed, 2019)On the basis of speciation by nuclear magnetic resonance (NMR) spectroscopy, heat of absorption, and pH data, the reactions occurring in aqueous MAPA (3-(methylamino)propylamine), DEEA (2-(diethylamino)ethanol), and their ... -
Describing CO2-Absorbent Properties in AspenPlus
Ros, Jasper; Brilman, Derk; Bernhardsen, Ida; Knuutila, Hanna K (Journal article; Peer reviewed, 2019)For the modelling of novel solvent systemsfor CO2-capture in AspenPlus®, data fitting of physical-chemical properties is needed. In this work the challenges and results are presented for fitting such experimental data for ... -
Effect of liquid viscosity on the performance of a non-porous membrane contactor for CO2 capture
Bernhardsen, Ida; Ansaloni, Luca; Betten, Hanne Kalvøy; Deng, Liyuan; Knuutila, Hanna K (Journal article; Peer reviewed, 2019)The effect of liquid viscosity on the performance of a non-porous membrane contactor is important to study for a proper solvent selection and process design. In this work, the overall mass transfer coefficient for MEA- and ... -
Kinetics of CO2 absorption into aqueous solutions of 3-dimethylamino-1-propanol and 1-(2-hydroxyethyl)pyrrolidine in the blend with 3-(methylamino)propylamine
Bernhardsen, Ida; Knuutila, Hanna K (Journal article, 2019)The kinetics of CO2 absorption into unloaded aqueous solutions of 3-dimethylamino-1-propanol (3DMA1P) and 1-(2-hydroxyethyl)pyrrolidine (1-(2HE)PRLD) blended with 3-(methylamino)propylamine (MAPA) were studied in the ... -
Measurement and prediction of oxygen solubility in post-combustion CO2 capture solvents
Buvik, Vanja; Bernhardsen, Ida; Figueiredo, Roberta V.; Vevelstad, Solrun Johanne; Goetheer, Earl L.V.; van os, peter (Peer reviewed; Journal article, 2020)This work aims to understand oxygen solubility in pure and aqueous amine solvents for CO2 capture. Commercially available dissolved oxygen sensors were studied to evaluate whether these can be used for measuring oxygen ... -
Physical properties and reaction kinetics of CO2 absorption into unloaded and CO2 loaded viscous monoethanolamine (MEA) solution
Ramezani, Rouzbeh; Bernhardsen, Ida; Di Felice, Renzo; Knuutila, Hanna K (Journal article, 2021)In order to comprehensively understand how solvent free concentration and high viscosity affect mass transfer and consequently absorption flux, CO2 absorption kinetics into unloaded and CO2 loaded viscous monoethanolamine ... -
Vapour-liquid equilibrium study of tertiary amines, single and in blend with 3-(methylamino)propylamine, for post-combustion CO2 capture
Bernhardsen, Ida; Trollebø, Anastasia Aleksandrovna; Perinu, Cristina; Knuutila, Hanna K (Peer reviewed; Journal article, 2019)
