A Study of Mass Transfer Kinetics of Carbon Dioxide in (Monoethanolamine + Water) by Stirred Cell
(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 ... -
An experimental investigation of rapid boiling of CO2
(Journal article; Peer reviewed, 2014-09-27)Storage of pressurized liquified gases is a growing safety concern in many industries. Knowledge of the thermodynamics and kinetics involved in the rapid depressurization and evaporation of such substances is key to the ... -
Carbon dioxide emission reduction by increased utilization of waste-derived fuels in the cement industry
(Conference report, 2007)Considerable reductions in Norway's emissions of greenhouse gases like CO2 are required to meet the commitments of the Kyoto Protocol. CO2 emissions from cement clinker production originate from decarbonation of limestone ... -
CO2 absorption in alkaline solution
(Master thesis, 2008)Density and viscosity for monoethanolamine (MEA) solution are important for estimation of mass transfer in CO2 removal by absorption. A literature search on density, viscosity, surface tension and contact angle was performed. ... -

(Master thesis, 2015-09-25)The aim of this work is to determine partial pressures and CO2 loadings of primary amine aqueous solutions such as monoethanolamine, 3-amino-1-propanol, 4-amino-1-butanol and 5-amino-1-pentanol at the equal vapor liquid ... -
Cost estimation methods for CO2 capture processes
(Doctoral dissertations at the University of South-Eastern Norway;140, Doctoral thesis, 2022-10-12)Cost engineering and economic assessment play a crucial role in evaluation of CO2 capture technologies and energy systems. Cost is one of the key decisive factors when considering industrial deployment of a technology. ... -
Degradation of Aqueous 2-Amino-2-methyl-1-propanol for Carbon Dioxide Capture
(Doctoral dissertations at TUC;2013:1, Doctoral thesis; Peer reviewed, 2013-01-29)Absorption-stripping with aqueous 2-amino-2-methyl-1-propanol (AMP), and especially AMP blends with other amines, such as monoethanolamine (MEA) and piperazine (PZ), presents an attractive option for carbon dioxide (CO2) ... -
Diffusion of CO2 through polymer membranes
(Master thesis, 2017)Food industry use polymers as packaging to protect and maintain high quality and freshness of the product during distribution and storage. Polymers are permeable for gases like O2, CO2 and water vapor. Simulation models ... -
Energy and Economic Analysis of Improved Absorption Configurations for CO2 Capture
(Journal article; Peer reviewed, 2017)The shortcoming of amine-based CO2 absorption technology is the large heat demand for desorption and it requires huge capital investment. Thus, it is expedient to comprehensively and critically analyse alternative process ... -
Equilibria of MEA, DEA and AMP with Bicarbonate and Carbamate: a Raman Study.
