Embryo research of a reactor to produce CO2 hydrates
(Master thesis, 2017)The potential applications of carbon dioxide hydrate have attracted many interests over the past decade. CO2 transmission in the form of hydrate is an alternative way of transportation in CCS chain, however, the CO2 hydrate ... -
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 ... -
Environmental impact assessment of biochar in anaerobic digestate
(Master thesis, 2022)Climate change and unsustainable crop production are among the most prominent environmental issues and viable solutions must be looked for. A circular economy approach by recycling biochar-digestate back to agriculture as ... -
Environmental production : use of waste materials in cement kilns in China
(Master thesis, 2008)This report mainly talks about utilizing the cement kiln to dispose wastes. In China, there are huge amounts of wastes can be produced every year. China government pays more attention to the environmental protection. 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 ... -
Experimental investigation and simulation of ignition of fuel-air clouds with fuel mixtures of hydrogen and hydrogen-carrying fuels
(Master thesis, 2021)Hydrogen is playing an increasingly important role as the world moves to a low-carbon energy system, but combustion properties of this gas are very different from other hydrogen-carrying fuels that can lead to difficulties ... -
Experimental measurements of diesel spray in an inert gas generator
(Master thesis, 2017)A 90° Y-jet atomizing nozzle with 3 bores was experimentally tested in a science facility at University College of Southeast Norway. The nozzle is producing a diesel fuel spray for a pilot flame in an IGG system for marine ... -
Framework for carbon footprint analysis of Scope 3 emissions
(Master thesis, 2022)To accelerate actions towards the goal of the Paris Agreement, new greenhouse gas (GHG) emission targets have been set by the European Union and Norway towards achieving climate neutrality by 2050. As a result, new legislation ... -
Grey-box models for estimation of heating times for buidings
(Master thesis, 2016)Energy-usage in buildings is responsible for a large part of the total demands on energy production. Models are required to estimate the heating and cooling times of buildings, thus allowing a control system to accurately ... -
Investigation of Bioprocess for Industrial Wastewater Treatment
(Master thesis, 2016)A pilot scale Hybrid Vertical Anaerobic Biofilm (HyVABr) reactor was applied to the treatment of waste oil refinery wastewater. The reactor comprised a bottom anaerobic digestion stage operated as an Up-flow Anaerobic ... -
Investigation of Sludge in Anaerobic Sludge Bed Bioreactor
(Master thesis, 2016)The variation in granular sludge properties from various up-flow anaerobic sludge bed (UASB) reactors and the application of coffee grit as a physical model to characterize granular sludge were investigated in this study. ... -
Investigation to improve the coagulation process at Lillevik WWTP, Larvik
(Master thesis, 2015-10-30)Investigation to improve the wastewater treatment, focusing on the coagulation process, at Lillevik WWTP has been performed. Four activities were carried out for this purpose: 1. Investigate variations and correlations for ... -
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 ... -
Life Cycle Assessment of Biogas Upgradation Using Microbial Electrosynthesis
(Master thesis, 2022)This thesis evaluates a life cycle assessment (LCA) framework for biogas upgradation. A study and evaluation were conducted by comparing high-pressure water scrubbing (HPWS) for biogas upgrading and integration of the ... -
Life Cycle Assessment of Mobile Batteries for Emission-Free Construction Sites
