(Masteroppgave/UIS-TN-IMN/2014;, Master thesis, 2014-08-13)‘Lab on a chip’ refers to devices and methods for controlling and manipulating fluid flows at micro levels. These microfluidic devices used for manipulating and controlling fluids are widespread now, and are used in many ... -
New Microwave Technology for the Treatment of Drill Cuttings
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017)The focus of this thesis was to investigate the limitations of the new microwave susceptor technology. The technology offers promising opportunities in the treatment of oil contaminated drill cuttings to meet OSPAR and oil ... -
Optimization of chemical and mechanical disintegration process of drilling fluids.
(Masteroppgave/UIS-TN-IMN/2015;, Master thesis, 2015-06)Drilling fluids are essential to conduct any drilling process. The amount of oil-based mud used daily is significant. Additives present in an oil-based mud ensure both unique properties and require proper waste treatment. ... -
Performance of sequencing batch reactors for nutrient removal using salsnes filter fine mesh sieves as a primary treatment
(Masteroppgave/UIS-TN-IMN/2013;, Master thesis, 2013)This study investigated the performance of sequencing batch reactors (SBR) for nitrification and denitrification. Bench scale Salsnes Filter (SF) was used as a primary treatment to provide wastewater with different organic ... -
Potential effect of the typhoon valve, vase study of Oseberg C platform
(Masteroppgave/UIS-TN-IMN/2013;, Master thesis, 2013)Onshore and offshore facilities produce oil and gas worldwide. Globally, the daily oil production reached 83.6 million barrels per day in 2011. During the following years the production has continued increasing. It was ... -
