Applicability of NRTL Model for Prediction of the Viscosity of Alkanolamine + Water Mixtures
Karunarathne, Sumudu S.; Øi, Lars Erik (Journal article; Peer reviewed, 2019)This study discusses the applicability of the non-random two-liquid (NRTL) model to represent viscosity for MEA (monoethanol amine) + H2O and AMP (2-amino-2-methyl-1-propanol) + MEA (monoethanol amine) + H2O mixtures under ... -
CFD Study of Particle Flow Patterns in a Rotating Cylinder Applying OpenFOAM and Fluent
Dissanayake, Susantha; Karunarathne, Sumudu S.; Lundberg, Joachim; Tokheim, Lars-André (Journal article; Peer reviewed, 2017)A rotating cylinder (RC) is a common type of reactor used in the industry, the most typical example being a cement kiln. The particle flow pattern inside such a unit is necessary for the mass and energy transfer, and this ... -
Comparison of the influence of drag models in CFD simulation of particle mixing and segregation in a rotating cylinder
Karunarathne, Sumudu S.; Tokheim, Lars-André (Journal article; Peer reviewed, 2017)CFD modelling was used to simulate particle segregation in a transverse plane of a rotating cylinder under different particle-particle drag models. The Eulerian method was used to model the dense particulate phases in the ... -
Density and Viscosity Correlations for Aqueous 3-Amino-1-propanol and Monoethanol Amine Mixtures
Karunarathne, Sumudu S.; Øi, Lars Erik (Journal article; Peer reviewed, 2019)Density and viscosity data and relevant correlations are essentially needed to perform mathematical modelling and simulations for the design of process equipment. Correlations that are developed to cover a range of ... -
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 ... -
Physicochemical data for amine based CO2 capture process
Karunarathne, Sumudu S. (Doctoral dissertations at the University of South-Eastern Norway;72, Doctoral thesis, 2020-06-18)Amine based post-combustion carbon capture is a highly discussed CO2 removal method from flue gas. Large-scale CO2 capture facilities with effective solvents are required to make a significant impact on reducing CO2 emissions ...
