Biological hydrogen sulfide removal with nitrate
(Doctoral dissertations at the University of South-Eastern Norway;11, Doctoral thesis, 2018-09-28)Aim: Hydrogen sulfide is a major occupational hazard in agriculture, industry, and sewage processing; its presence leads to corrosion. Thus, hydrogen sulfide removal is obligatory. These investigations aim to evaluate the ... -
Bubbling Fluidized Bed Behaviour for Biomass Gasification
(Doctoral dissertations at the University of South-Eastern Norway;35, Doctoral thesis, 2019-06-21)The need to cut down the high dependency on the fossil fuels requires sustainable alternative energy resources. Aside that the stock of fossil fuels is depreciable, the energy source also accounts for the major contribution ... -
Capabilities of anaerobic granular sludge bed process for the treatment of particle-rich substrates
(Doctoral dissertations at the University of South-Eastern Norway;56, Doctoral thesis, 2020-01-17)High-rate anaerobic reactors have qualities that make them more attractive for anaerobic digestion of organic substrates compared to traditional reactors such as Continuous Stirred Tank Reactor (CSTR). These qualities ... -
Carbon Dioxide Capture by Chemical Absorption: Energy Optimization and Analysis of Dynamic Viscosity of Solvents
(Doctoral dissertations at the University of South-Eastern Norway;26, Doctoral thesis, 2019-02-11)Global warming resulted from the emissions of greenhouse gases; especially carbon dioxide has received widespread attention. The concentration of CO2 in the atmosphere reaches 400 ppmv and that is a considerably high value ... -
