Application of autonomous inflow control valve for enhanced bitumen recovery by steam assisted gravity drainage
(Master thesis, 2022)Production of bitumen through the thermal process, SAGD, is of interest since the warmed bitumen can be easily produced by aid of gravity towards the horizontal production wells. This approach beside its advantages has its ... -
Application of electron shuttle on anaerobic digestion for carbon dioxide reduction
(Master thesis, 2023)In anaerobic digestion, organic wastes are decomposed in the absence of oxygen primarily to produce biogas, which consists of methane and carbon dioxide. The methane content in biogas can be optimized by reducing carbon ... -
Aspen HYSYS process simulation and Aspen ICARUS cost estimation of CO2 removal plant
(Master thesis, 2010-06-25)An Aspen HYSYS model of CO2 removal was developed and modified with a split-stream configuration in order to reduce energy consumption in the reboiler. The model has been calculated with variation of parameters to optimize ... -
Assessment of CFD methods in predicting flow regime and pressure gradient in two phase gas-liquid vertical flow
(Master thesis, 2020)Available tools for dealing with multi-phase flows are not effective with complex geometries such as process piping with combination of horizontal and vertical pipes, bends and valves. However, rapid development of ... -
Biodegradation of waste amines under anaerobic, micro-aerobic and aerobic conditions
(Master thesis, 2008)Monoethanolamines (MEA) are commonly used as adsorbent in CO2 capture plants. MEA are degraded when used and become a waste product. 3 series of BOD test as well as 9 cases of syringe batch experiments under anaerobic, ... -
Boil-off gas handling for LNG-carriers with a low-swirl burner
(Master thesis, 2018)Wärtsilä is looking into a new technology for boil-off gas handling. The technology chosen for further research is a low-swirl burner. This burner has shown promising NOx emission results which is a problem inside the ... -
CFD study of a fluidized bed
(Master thesis, 2008)The aim of this thesis is to investigate the momentum exchange between the phases in a bubbling fluidized bed. The momentum exchange can be described by a drag model. Several drag models with different assumptions are ... -
CFD Validation of transient subsea gas plume model
(Master thesis, 2017)Subsea gas blowouts are often a significant risk contributor to offshore installations. It is important to understand plume that is created by the blowout. Different plume models were investigated. CFD model in ANSYS Fluent ... -
CFD-Simulations of Hydrogen Gas Explosion using the PDRFoam solver in OpenFOAM
(Master thesis, 2024)The gas, oil, and chemical industries face persistent threats from the accidental release of flammable gases, which can lead to catastrophic explosions. Hydrogen, increasingly popular as an alternative fuel, presents unique ... -
CFD-Simulations of inhomogeneous H2-air explosions
(Master thesis, 2021)Since demands for energy resources increase globally in recent years due to growth of application consumption, finding alternative resources for traditional fossil fuels raises. These current fuels are diminishing continuously ... -
Change in flame front area over time with premixed combustion across an obstacle
(Master thesis, 2018)This thesis is a joint project of USN, and CMR Gexcon to explore the changes in flame front area over time with premixed combustion across an obstacle. The objective of this thesis is to make a literature review on ... -
