Biodiesel by acid-catalyzed transesterification with butanol
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2012-07-11)Jatropha oil and Rapeseed oil was transesterified with n-butanol by the use of H2SO4. Before conducting the experiments a review of the effect of alcohol type was preformed. Alcohols from methanol to butanol, branched and ... -
Biological treatment of industrial wastewater for biogas production
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)Anaerobic biodegradation is a method of degradation that converts approximately 90% of the available chemical energy (in the form of organic material), into gas methane. Apart from the economic value of the methane gas ... -
Carbide formation on carbon steels in CO2 corrosion by use of applied anodic current
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)The present study aims to validate the method in enriching of iron carbide surface from carbon steels in CO2 corrosion. Applying an anodic current to carbon steel electrodes by galvanostatic measurement was a selected ... -
Characterization of ranomafana lake water quality - antsirabe madagascar
(Masteroppgave/UIS-TN-IMN/2009, Master thesis, 2009)Analyses of water quality parameters in Ranomafana Lake showed that the lake is hypereutrophic. It receives untreated wastewater from Antsirabe municipality by three main inlets: the North West inlet, the North inlet and ... -
Cold water coral Lophelia Pertusa biosensor
(Masteroppgave/UIS-TN-IMN/2014;, Master thesis, 2014-06-30)The oil and gas industry is required to have a monitoring capacity that makes it possible to fulfill the regulatory requirements in the areas they operate today and intend to operate in the future. Because of the relative ... -
Design and cost evaluation of anaerobic bioreactor for industrial waste
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06-21)Industrial wastewater with very high Total Organic Carbon (TOC) is a potential substrate for anaerobic treatment. Continuous Flow Stirred Tank Reactor (CSTR) is the common model of reactor used to treat various kind of ... -
DREAM (Dose-related Risk and Exposure Assessment Model) as a tool to predict biomarker responses in offshore produced water discharge situations
(Masteroppgave/UIS-TN-IMN/2009, Master thesis, 2009-11-25)Every year, approximately 200 million tones of produced water are discharged into the sea by the Norwegian oil industry. Although rapidly diluted, due to its large amount and possible long term (chronic) effects, the ... -
Drift og optimalisering av flash separatoren i en glykol reclamation enhet
(Masteroppgave/UIS-TN-IMN/2009;, Master thesis, 2011)Monoetylenglykol (MEG) benyttes ofte som inhibitor for å unngå hydrater i subsea gasstransportrør. MEG er en miljøvennlig inhibitor, som kan resirkuleres om regenerering benyttes. Regenerering av MEG involverer to trinn; ... -
