Modelling Bio-Electrochemical CO2 Reduction to Methane
(SINTEF Proceedings;4, Chapter; Conference object; Peer reviewed, 2019)The most common platform for biogas process modelling, ADM-1, was extended adding the bio-electrochemical active CO2 reduction to CH4 reaction. The Nernst expression was incorporated as Monod-type kinetic expression to ... -
Modelling combustion of pulverized coal and alternative carbon materials in the blast furnace raceway
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)The impact of injection lance design and injection materials on the combustion conditions inside the raceway of the blast furnace has been investigated. Operational injection tests in LKAB’s Experimental blast furnace have ... -
Modelling of bubble dynamics in slag during its hot stage engineering
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)Silica-rich additives are injected into the slag with N2/O2 as carrier gas to stabilize free lime in BOF (Basic Oxygen Furnace) steelmaking slag. In order to understand the mixing behaviour of the additives, bubble dynamics ... -
Modelling of chemical reactions in metallurgical processes
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)Iron-ore reduction has attracted much interest in the last three decades since it can be considered as a core process in steel industry. The iron-ore is reduced to iron with the use of blast furnace and fluidized bed ... -
Modelling of fluid dynamics, mass transfer and chemical reaction in bubbly flows
(SINTEF Proceedings;2, Chapter; Peer reviewed, 2017)Mass transfer from gas bubbles to the surrounding liquid or vice versa is an important consideration in chemical engineering. Frequently such absorption or desorption processes are accompanied by a chemical reaction in the ... -
Modelling of interaction between turbines and terrain wakes using pragmatic approach
(SINTEF Proceedings;2, Chapter, 2017)Kongsberg Digital (KDI) is currently developing a decision support system for wind farms (Kongsberg EmPower). The objectives of Kongsberg EmPower are to optimize the total power production from a wind farm, forecast the ... -
MODELLING OF MASS TRANSFER IN A STEELMAKING LADLE
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Mass transfer between liquid steel and slag is an important point during secondary metallurgy for prediction of the chemical reaction rate and adjustment of liquid steel composition. We want to study this phenomenon in ... -
Modelling of particle transport and bed-formation in pipelines
(SINTEF Proceedings;1, Chapter, 2015)Particle transport and bed formation in gas and condensate pipelines could occur under various flow regimes, from dilute flows to high mass-loading conditions, to conditions where particle beds form in the pipeline. Proper ... -
