      The NOx reduction system installed at Norcem Brevik is based on the SNCR technology. It was installed in 2012 and substantial reduction of NOx has been achieved. However, it has never been performed experiments or optimizations ...
    • Gas-to-gas heat exchanger for heat utilization in hot CO2 from an electrically heated calcination process 

      Jacob, Ron (Master thesis, 2019)
      Thesis was done with the objective of evaluating a gas to gas heat exchanger which will be used to recover heat from hot calciner exit gas from an electrically heated calcination process. Shell and tube heat exchanger ...
    • Grey-box models for estimation of heating times for buidings 

      Brastein, Ole Magnus (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 ...
    • Heat transfer mechanisms in MV load break switches 

      Øygarden, Stein (Master thesis, 2017)
      This report is part of an ongoing research project between University college of Southeast Norway and ABB Power product division. This report focuses on the heat transfer from two load break switch (LBS), normally used in ...
    • Heating of buildings with focus on measurement and control 

      Krogstad, Stian (Master thesis, 2015-09-25)
      In Norway 60% of all energy is commonly used for heating, during cold winters this number is seen to rise even higher. Any reduction in the standby power used for heating will result in large power savings. In this thesis ...
    • Hydrogenolysis of methyl formate over copper nano particles 

      Amundsen, Hilde Hauge (Master thesis, 2016)
      Hydrogenolysis of methyl formate has been proposed as a part of an alternative route for methanol production. Copper catalyst for the hydrogenation of ester to alcohol is a catalyst commonly used due to its high selectivity ...
    • Improved flow management of Lake Toke 

      Kvam, Kristian D. (Master thesis, 2017)
      The Telemark University College (TUC) Flood server is an advisory system that assist in the regulation of the flood gates at Dalsfos hydroelectric dam. A large flood in September 2015 revealed that the model and data storage ...
    • Improved oil recovery and the study of CO₂ storage in oil/gas reservoirs and aquifers 

      Anubueze, Ugwe Ambrose (Master thesis, 2016)
      As the world’s energy needs grow, several techniques have been introduced for an improved oil recovery (IOR) and secured storage of CO₂. Such techniques include the use of water injection, CO₂ for Enhanced Oil Recovery ...
    • Improving snow melt systems energy performance

      The Object of this report is the district heating snow melt system installed in Notodden, Norway.The heat is generated by 4.7MW woodchip burner, together with oil and electrical boilers to cover peak loads.The heat is ...
    • Improving the design of MV load-break switch contacts 

      Thøgersen, Espen (Master thesis, 2019)
      The breaking of currents either during maintenance, faults, or overload is common in load-break switches. Because switches are usually placed before critical installations it is important that their designs implementations ...
    • Influence of thermal radiation in MV switchgear 

      Gløsmyr, Tonje (Master thesis, 2019)
      When developing MV switchgear units it is important that the finalized product is within IEC maximum temperature rise limit. When a switchgear unit is developed it is continuously tested until it meets the requirements, ...
