Co-simulation-based optimal reactive power control in smart distribution network
(Peer reviewed; Journal article, 2023)The increasing integration of distributed energy resources such as photovoltaic (PV) systems into distribution networks introduces intermittent and variable power, leading to high voltage fluctuations. High PV integration ... -
CO2 Absorption Efficiency and Heat Consumption Measured at High Gas to Liquid Ratios in Laboratory Rig
(Journal article; Peer reviewed, 2017)A laboratory rig for CO2 absorption into amine solvents including desorption has been in operation at University College of Southeast Norway for several years. Measurements of CO2 removal efficiency and heat consumption ... -
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. ... -
CO2 BLEVE (Boiling Liquid Expanding Vapor Explosion)
(Master thesis, 2009-06-26)Boiling Liquid Expanding Vapor Explosion (BLEVE) has caused many accidents in industry, while research with BLEVE is still limited with scarcity of experimental data. Among all pressurized liquefied gases (PLGs), CO2 plays ... -
