    Bregge, Christine (Master thesis, 2015-11-06)
    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 ...
  • Stochastic flood control using MPC of Kragerø waterways 

    Dhakal, Bhuwan (Master thesis, 2015-11-06)
  • Deterministic flood control using MPC on the Kragerø waterways 

    Evensen, Robin (Master thesis, 2015-11-06)
    The Kragerø Waterways consist of 5 power plants downstream after Lake Toke, Dalsfos is the first of these power plants. As a deterministic flood control of Lake Toke and Dalsfos there has been designed a MPC. The MPC uses ...
  • Simulating open channel flow for drill mud mass flow measurement, part II 

    Basnyat, Prabin (Master thesis, 2015-11-06)
    Advancement in oil drilling technology, particularly managed pressure drilling requires better knowledge of return drill mud flow. Since the mud outflow is in an open channel, it is proposed to use flume with constriction ...
  • CO2 for enhanced oil recovery and secure storage of CO2 in reservoirs 

    Li, Yunhang (Master thesis, 2015-10-30)
    CO2-EOR(Enhanced Oil Recovery) is an effective and useful technology that can not only increase the oil production to meet the increasing need for energy around the world, but also mitigate the negtive influence of global ...
  • Investigation to improve the coagulation process at Lillevik WWTP, Larvik 

    Kibiakova, Hanna (Master thesis, 2015-10-30)
    Investigation to improve the wastewater treatment, focusing on the coagulation process, at Lillevik WWTP has been performed. Four activities were carried out for this purpose: 1. Investigate variations and correlations for ...
  • Near well simulation and modelling of oil production from heavy oil reservoirs 

    Malagalage, Anjana (Master thesis, 2015-10-30)
    Heavy oil reservoirs cover up two third of the world's hydrocarbon reservoirs. Even though they are a vast energy reserve, heavy oil recovery is not considered economical due to its high viscous property. Generally horizontal ...
  • Near well simulation of heavy oil reservoir with water drive 

    Ediriweera, Mahesh Priyankara (Master thesis, 2015-10-30)
    The Depletion of oil production and the low recovery rate are major challenges faced in oil production at Norwegian continental self. Several studies have shown that considerable amount of oil still remains after the well ...
  • Ponds and anaerobic digestion combination 

    Bjerkely, Magnus (Master thesis, 2015-10-30)
    Production of biogas from small farms in China is decreasing because of the decrease in farm animals at these farms. It is needed a replacement for the animal manure. The replacement looked into in this paper is an algae ...
  • Optimization of biomass gasification reactor using Aspen Plus 

    Sun, Ke (Master thesis, 2015-10-30)
    Biomass is an ideal renewable and clean energy resource. Counties all over the world are paying more and more attention to biomass because it can effectively reduce greenhouse effect due to its zero carbon dioxide emission. ...
