Anaerobic Conversion of Glycol Rich Industrial Wastewater to BiogasAnaerobic Conversion of Glycol Rich Industrial Wastewater to Biogas
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Oil and gas industries generate large volumes of wastewater during exploitation and processing of oil and gas. Industrial wastewater contains glycols along with other organic and inorganic compounds. It is essential to ... -
Anaerobic treatment of glycol contaminated wastewater for methane production
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)Glycols are usually used in the offshore gas industry as hydrate inhibitor in gas pipelines laid deep under the sea. Glycols, in its use, are contaminated by dissolved salts from formation water together with scaling and ... -
Anaerobic Treatment of Industrial Wastewater under Psychrophilic Conditions (10 °C ) using Upflow Anaerobic Sludge Blanket (UASB) reactor, Lab Studies.
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06-15)The main objective of this study was to investigate the performance of UASB reactors for their efficiency of removing COD and producing methane gas at psychrophilic temperature, 10 °C by treating high strength municipal ... -
Analysis of by-products from XLPE Production for cable insulation
(Masteroppgave/UIS-TN-IMN/2009;, Master thesis, 2009)Polyethylene is used in the manufacturing of cables. Because of the amount of high voltages which is transmitted through the cables at elevated temperatures, crosslinking of PE is necessary for stabilizing the insulation. ... -
Analysis of corrosion resistance property of cold bended 316L and 6Mo stainless steel pipes
(Masteroppgave/UIS-TN-IMN/2014;, Master thesis, 2014-06-16)The variation in mechanical properties after cold deformation (bending) of pipes is one of the interesting subjects in material science. One major quality the material should possess is high corrosion resistance after ... -
Biodegradation and chemical characterization of petroleum diesel hydrocarbons in seawater at low temperatures
(Masteroppgave/UIS-TN-IMN/2010;, Master thesis, 2010-06)Petroleum hydrocarbons are a major source of marine contamination. Biodegradation, which is fundamental for the natural attenuation of these hydrocarbons in nature, involves mineralization or transformation of organic ... -
