Numerical Study of Mass Transfer Limitations in a Bioreactor Operated in the Heterogeneous Flow Regime
(Master thesis, 2017)With the increased focus on detaining a more environmental friendly industry, biological processes have been given more attention over the last years. Such a biological process is single cell protein (SCP) production, ... -
Once-Through Gas-to-Liquid Process Concept for Offshore Applications
(Master thesis, 2015)The worlds energy demand is increasing, and at the same time the amount of easily accessible oil is reduced. Associated gas for most off-shore applications are flared or injected in the reservoir due to transportation ... -
Optimization of the Numerical Solution of the Population Balance Equation
(Master thesis, 2016)The population balance equation (PBE) is a frequently applied equation in the modeling of multiphase reactors. Accurate solution of the PBE is important in order to have a precise estimate of the interfacial area, which ... -
Process Optimization of Biogas Upgrading with AMP Using Pilot Plant Data and Simulations with Aspen Plus
(Master thesis, 2016)In gaseous biofuel production mixtures of CO2, CH4 and/or H2 and are typically produced. When using these gaseous for example in fuel cell applications (H2) or as vehicle fuel (CH4) gas upgrading is needed. Upgrading ... -
Process Simulation of a Hybrid Fuel Cell System for Clean and Highly Efficient Offshore Power with Carbon Capture
(Master thesis, 2017)Today, offshore power is mainly produced onsite by gas turbines and the process is responsible for the majority of the CO2-emissions from the Norwegian offshore industry. To reduce CO2-emissions offshore, electrification ... -
Removal of SO2 from Flue Gas - Study of the Regenerable Labsorb Process
(Master thesis, 2015)Sulphur dioxide (SO2) is a well-known air pollutant, and is primarily formed as a by-product when fossil fuels are burned at power plants. Due to stringent emission regulations, well-designed and efficient flue gas ... -
Renewable CO2 recycling and synthetic methanol production
(Master thesis, 2018)The demand for energy in the world is increasing, and with that the need for new energy sources. A problem with fossil fuels as an energy source, is the huge amount of CO2 that comes with it. Consequently, the demand for ... -
Simulation and Model Verification of the Dynamic and Steady State Behavior of the CO2 Capture Plant at TCM.
(Master thesis, 2015)Post-combustion CO2 capture (PCC) with amines is the most mature technology for CO2 capture, and is considered to be an important part of future carbon capture and storage projects. A dynamic model of a PCC amine plant ... -
Simulation of Combined Hydrate Control and H2S Removal Using Aspen Plus
(Master thesis, 2016)Removal of water (H2O) and acid gas contaminants, like hydrogen sulfide (H2S) and carbon dioxide (CO2), are essential in natural gas purification. Due to gas quality specifications and protection of installed equipment ... -
Simultaneous precipitation of Calcium Sulfate and Calcium Carbonate during MEG regeneration
(Master thesis, 2016)Simultaneous precipitation of calcium carbonate and calcium sulfate in supersaturated solutions containing a MEG-water concentration containing 0, 50 or 90 wt% MEG, was investigated in a bath setup at constant pressure and ... -
Solar Thermal Hydrogen Production: A Dynamic Reactor Model for the Hercynite Cycle
(Master thesis, 2016)The focal point of this thesis is the production of hydrogen. Hydrogen is classified as a secondary energy source and must, analogous to electricity, be efficiently produced from some primary energy source. This primary energy ... -
SolarThermal Splitting of Water to Hydrogen with Co-doped-hercynite - Testing and Characterisation / Heat integration
(Master thesis, 2016)By using concentrated solar energy, it is possible to split water to hydrogen and oxygen, or eventually CO2 to CO and oxygen, by using redox materials at temperatures between 1200 1500 °C. One of the best redox materials ... -
Strong Bicarbonate Forming Solvents for Absorption of CO2 - Experimental Determination and Modelling of Vapor-Liquid Equilibria Data
(Master thesis, 2016)Absorption by amines provides a technology for CO2 capture. New solvents are of interest to ameliorate the process, and the two alkanoamines 2-piperidine-ethanol (2-PPE) and 1-(2-hydroxyethyl)-pyrrolidine (1-2HE-PRLD) were ... -
Study of the Particle Properties of Iron Oxide/Hydroxide Precipitate in Nickel Production
(Master thesis, 2017)The background for this thesis was crystallization of iron in nickel production at Glencore and a review of filterability properties of iron oxide/hydroxide precipitate. The nickel plant in Kristiansand produces nickel and ... -
Subsea regeneration of triethylene glycol (TEG) for natural gas dehydration.
(Master thesis, 2017)The scope of this thesis was to examine the use of pervaporation technology with membranes for the regeneration of triethylene glycol (TEG) in natural gas dehydration. To reduce the need for offshore installations, subsea ... -
Subsea Separation and Water Injection at Luno II - Conceptual Design and Control Assessment
(Master thesis, 2017)Subsea separation and water re-injection give rise to production from oil fields earlier considered economically unfit and give a longer production life to existing fields. This thesis addresses the design of a subsea ... -
