Model Development for Optimal Operation of the District Heating Facilities of Fortum Oslo Varme - Using Genetic Algorithm, Recurrent Neural Network and Multiple Linear Regression
(Master thesis, 2018)Recent development in the energy sector in Norway has made district heating increasingly relevant. In particular, the increased demand for electric power, has contributed to make district heating more important. A well ... -
MultiBooster instability and surge - Ustabilitet og surge i MultiBooster
(Master thesis, 2016)Industry has lately turned the focus on subsea processing as a tool to enable new developments where the technology needs are increasing. Multiphase pumping ( boosting ) plays a key role in the increase of production and ... -
Near zero emission energy export and electric power supply based on natural gas
(Master thesis, 2018)In this study, a techno-economic analysis of value chains/cases for near zero emission energy export and power supply to Continental Europe, based on natural gas extracted in Norway and integration of carbon capture and ... -
New technologies for purification and carbon capture in hydrogen production from natural gas
(Master thesis, 2015)In a society increasingly concerned with environmentally friendly solutions for energy extraction, hydrogen is expected to be an important energy carrier. Hydrogen can originate from various feedstocks, where fossil fuels ... -
Oil Based Solar Concentrator with Heat Storage
(Master thesis, 2016)A test system for storing solar thermal energy in the form of hot oil is constructed and tested. The motivation for the work is the need for a thermal energy storage which provides heat, from solar concentrators, for food ... -
Optimized and Cost Efficient Industrial Heat Pumps based on Low Grade Waste Heat
(Master thesis, 2016)The industrial sector is a large consumer of energy. Globally, this sector accounts for over half of the energy used. As anthropogenic emissions increase, and the consequences of these emissions become more evident, the ... -
Process simulation and evaluation of options for heat and power generation on offshore oil and gas installations
(Master thesis, 2016)In the efforts of trying to reduce global greenhouse gas emissions, the Norwegian oil and gas industry is looking for ways to improve efficiencies when supplying heat and power offshore. By making a scenario of a platform ... -
Simulation of a freezing system for pelagic fish using open cycle with air as working fluid
(Master thesis, 2018)As a result of increased focus on the environment, a decision to phase out the use of gases with global warming- and ozone depletion potential, was made. In this master thesis, a state-of-the-art freezing application for ... -
Simulations and experiments on a Solar-Assisted Heat Pump Water Heater - a comparison between R22 and R290 as working fluid
(Master thesis, 2016)Solar Assisted Heat Pumps (SAHP) use solar irradiation to boost the evaporation temperature. The experimental setup used in this thesis was located in Shanghai in China and heats water for domestic purposes. The experimental ... -
Small scale severe slugging experiments with several risers
(Master thesis, 2015)Severe slugging is a multiphase flow phenomenon that can occur in flowline-riser systems when conditions allow it. Its periodical fluctuations in pressure and mass flow can cause operational problems in downstream processing ... -
Systemløsninger for håndtering av lavtrykksgass i LNG-eksportterminaler
(Master thesis, 2017)Det er analysert ulike løsninger for håndtering av lavtrykksgass fra LNG-anlegg. Lavtrykksgass er en blanding av metan og nitrogen i gassfase som dannes ved LNG-produksjon grunnet varmelekkasje, trykktap og pumpearbeid. I ... -
The Effect of Gas Kinetics on the Gas-Lift Efficiency for Viscous Oil in Vertical Pipe Flow
(Master thesis, 2015)For heavy oil, artificial lift can be applied to increase and stabilise production flow. How the gas kinetics, i.e. the lift-gas composition will influence this increase is the subject of this thesis and will be described ... -
Transient Modelling of Hydropower Plants
(Master thesis, 2016)Any changes of the volume flow through a turbine gives acceleration or deceleration of the masses of water in the penstock. This induces dynamic pressure changes in front of the turbine. A pressure transient must be ... -
Utilization of surplus heat from snow producing machines
(Master thesis, 2016)In this master thesis, four cases of snow supply have been evaluated under the condition that a 5 km track of ski conditions can be guaranteed from November to the end of April at a nordic ski arena in Granåsen, outside ... -
Utvikling av system for duggpunktskjøling i forretningsbygg
(Master thesis, 2016)I denne oppgaven studeres potensialet til et duggpunktskjølesystem i et forretnings- bygg plassert i Bergen. Det undersøkte systemet består av en adsorpsjonsrotor, duggpunktskjølere, et kjølebatteri og en regenererende ...
