Investigating Protein Adsorption on Hydrophobic and Hydrophilic Polymers for Antifouling Coatings
(Master thesis, 2023)Når overflater befinner seg i sjøvann vil ulike organismer fra sjøen adsorberes på overflaten. Dette fenomenet kalles marin begroing, og har vært et problem i årtusener. Første trinn i prosessen er typisk adsorpsjon av ... -
Investigating the Influence of Water Wash Design and Operating Conditions on MEA Emissions in Amine Scrubbing
(Master thesis, 2023)Karbonfangst spiller en avgjørende rolle i bekjempelsen av den presserende utfordringen med klimaendringer. Ettersom utslippene av drivhusgasser fortsetter å øke, har behovet for effektive strategier for å redusere ... -
Investigation into the Performance of Candle Filter Technology for the Separation of Metal Hydroxide Precipitates from an Aqueous Effluent
(Master thesis, 2014)The effluent treatment plant at Glencore Nikkelverk experiences the generation of liquid waste from various areas and processes in the plant. Being primarily a nickel refinery, but also producing copper and cobalt, the ... -
Investigation of a membrane contactor for CO2 capture from natural gas/biogas
(Master thesis, 2016)Carbon dioxide needs to be separated from natural gas or biogas streams and membrane contactors can be a very good alternative for it. In this work a poly(1-trimethylsilyl-1-propyne) supported by a polyvinylidene fluoride ... -
Investigation of a new application for cellulose nanocrystals: a study of the enhanced oil recovery potential by use of a green additive
(Journal article; Peer reviewed, 2018)Cellulose nanocrystals (CNC) were investigated for use in a potential new application, enhanced oil recovery. Core flooding experiments were performed on outcrop sandstone cores using CNC particles dispersed in low salinity ... -
Investigation of Adsorption of Surfactants onto Illite and Relations to Enhanced Oil Recovery Methods
(Master thesis, 2014)Surfactants have many applications in enhanced oil recovery (EOR) and for each of these applications, care must be taken in selecting the right surfactant. Surfactants tend to be a major portion of the costs associated ... -
Investigation of Adsorption of Surfactants onto Kaolinite and Relations to Enhanced Oil Recovery Methods
(Master thesis, 2014)Surfactant flooding is a well-established enhanced oil recovery (EOR) technique, but the economic feasibility of this method is a major concern due to the substantial misplacement and loss of expensive surfactants to the ... -
Investigation of C1+C1 coupling reactions in cobalt-catalyzed Fischer-Tropsch synthesis by a combined DFT and kinetic isotope study
(Journal article; Peer reviewed, 2019)Understanding the chain growth mechanism is of vital importance for the development of catalysts with enhanced selectivity towards long-chain products in cobalt-catalyzed Fischer-Tropsch synthesis. Herein, we discriminate ... -
Investigation of coalescence through film drainage modeling in chemical- and bioreactors with non-Newtonian continuous media
(Master thesis, 2021)Denne masteroppgaven tar for seg dreneringen av en ikke-Newtonsk film innfanget mellom to fluidpartikler for å modellere koalesens i kjemiske reaktorer og bioreaktorer. I litteraturen finnes det mange studier som utforsker ... -
Investigation of Fundamental Properties of Catalysts for Direct and Indirect Synthesis of DME
(Master thesis, 2014)Dimethyl ether (DME) has potential as an environmentally friendly fuel. The main advantage of DME as a fuel lies in its clean combustion; the emissions of soot and particulate matter, as well as NOx and SOx are significantly ... -
Investigation of interfacial tension of surfactant in low salinity water for enhanced oil recovery application
(Master thesis, 2013)Surfactant flooding is known as a very good method to improve oil recovery. Many experimental studies in laboratories have shown the effectiveness of this method to increase the percentage of oil coming up from the core ? ... -
Investigation of metal dusting corrosion process over UNS N08800 alloy
(Journal article; Peer reviewed, 2017)Metal dusting corrosion is a catastrophic degradation phenomenon that initiates on metallic surfaces of chemical process equipment at elevated temperature and under carburizing atmospheres. It proceeds by a gradual breakdown ... -
