Density and Viscosity for the Non-aqueous and Aqueous Mixtures of Methyldiethanolamine and Monoethylene Glycol at Temperatures from 283.15 K to 353.15 K
(Journal article; Peer reviewed, 2020)Nonaqueous and aqueous mixtures of methyldiethanolamine and monoethylene glycol form promising absorbents for the combined hydrogen sulfide removal and hydrate control, necessary in natural gas processing. In this direction, ... -
Density calculations of aqueous amine solutions using an excess Gibbs based model
(Peer reviewed; Journal article, 2019)Accurate representation of the physical properties of a solvent is essential for design and simulation of processes. Density and viscosity, for instance, have an important role in modelling and designing absorption and ... -
Density Functional Theory-Assisted Microkinetic Analysis of Methane Dry Reforming on Ni Catalyst
(Journal article; Peer reviewed, 2015)A comprehensive microkinetic model based on density functional theory (DFT) calculations is constructed to explore the reaction mechanism for dry methane reforming on Ni catalyst. Three low-index facets, namely, Ni(111), ... -
Describing CO2-Absorbent Properties in AspenPlus
(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 ... -
Description of Supercritical Water-Hydrocarbon Systems
(Dr. ingeniøravhandling, 0809-103X; 2001:53, Doctoral thesis, 2001)Water +n-alkane systems at high pressures and temperatures, including the critical region, have been studied and modeled. All fluids exhibit fascinating behaviour near the critical point. Thus, the thesis begins with a ... -
