Effects of nitrate addition on anaerobic digestion of high content organic substrate in semi-continuous fed reactors
(Master thesis, 2018)Biogasification can recover a significant portion of energy potential from organic wastes. In addition to energy recovery, it also offers waste stabilization. However, there is a need for more efficient process for digestion ... -
Predicting weather using ANN with free open weather data in Python
(Master thesis, 2018)Predicting the weather is important for a lot of fields including agriculture, construction and hydro-power and flood management. Currently mechanistic meteorology predictions are generated using heavy computing based ... -
Monitoring and process evaluation of continuous stirred biogas reactor under semi-continuous dosage of Ca(NO3)2
(Master thesis, 2018)Anaerobic digestion is a process typically used for the reduction of the organic load from sludge, with known advantages over other traditional processes being an energy producer in form of biogas. The economic viability ... -
Process simulation of CO2 absorption at TCM Mongstad
(Master thesis, 2019)Developing robust and predictable process simulation tools for CO2 capture is important for improving carbon capture technology and reduce man made CO2 emissions. In this thesis, five different scenarios of experimental ... -
Dispersion of hydrogen in confined spaces
(Master thesis, 2019)Usage of hydrogen as fuel gives rise to possible accidental risks due to leakage and dispersion. The highest risk from hydrogen leak is the formation of a large volume of the hydrogen-air mixture, which could be ignited ... -
Cost-effective and safe oil production from existing and near-future oil fields
(Master thesis, 2020)Despite the rapid progress in the area of renewable energy, fossil fuels will remain the world’s most important energy source for the foreseeable future. Therefore, in order to meet future energy demands, increasing the ... -
Evaluation of De-oiler Performance Using Numerical CFD Technique
(Master thesis, 2020)When producing oil from the reservoir, it comes together with water, gas, sand, and other impurities. Excluding gas, all of them are unexpected waste. The water or simply called produced water is the biggest problem due ... -
Modelling and evaluating of Compressed Air Energy Storage System
(Master thesis, 2020)With the worldwide increase on the use of renewable energy, efficient energy storage is needed to include intermittent renewable energy sources, such as wind and solar energy. One of the energy storage technologies that ... -
Simulation of Hydrogen Tank Refuelling
(Master thesis, 2020)As an alternative to fossil fuels and as a sustainable energy carrier, there are considerable interestsin investigating hydrogen. Hence, it seems significant to evaluate the behavior of hydrogen in refueling or storing. ... -
Syngas Fermentation Catalyzed by Electroactive Biofilm
(Master thesis, 2021)This report describes an experiment conducted to see whether syngas fermentation could be integrated into the single-cell microbial electrosynthesis process. In some gasfermentation strategies, the primary bottleneck is ... -
Modeling of evaporation of hydrogen during accidental releases
(Master thesis, 2021)Hopefully, in the near future, liquid hydrogen will be commonly utilized as energy. The cleanest fuel that the primary limit of producing and using it, is safety issues. High possibility safety issues are generated by large ... -
Design of an Industrial Chlorination Reactor using CPFD Simulations
(Master thesis, 2021)Aluminum is now the world's second most used metal. Since aluminum has a unique combination of appealing properties and functionalities, it allows for significant energy savings in many applications, such as vehicles and ... -
Modelling temperature transition and co-digestion in VEAS biogas process
(Master thesis, 2021)Anaerobic digestion (AD) is a well-established way to stabilise concentrated sludge produced in wastewater treatment (WWT) plants. The benefit of the process is the production of biomethane and digestate that can be used ... -
Enhanced Digestate Nitrification in Sequencing Batch Reactors (SBR)
(Master thesis, 2021)The liquid fraction of digestates from anaerobic digestion contains a high concentration of Ammonium, which can be transformed into liquid “organic fertilizer”. Direct application of these digestates as fertilizer would ... -
CO2 capture by MEA solvent: Chemical Speciation models of CO2 derived species & total solvent alkalinity by multivariate data analysis of FTIR spectra from the CO2 Technology Centre Mongstad
(Master thesis, 2021)This study is the next step of ongoing research at University of South-eastern Norway (USN) to enable multivariate analysis for industrial scale capture process. This study has been done in collaboration with Technology ... -
Kalsinering i en elektrisk varmet drop tube kalsineringsreaktor
(Master thesis, 2021)I et moderne sement ovn-anlegg er det kalsinering av CaCO3 som er hovedårsaken til CO2 utslipp. Omtrent 70 % av CO2 gassen blir skapt ved kalsinering, mens resten kommer fra forbrenning av drivstoff. Elektrifisering av ... -
Calcination applying H2 combustion in O2 in a CO2 rich atmosphere
