• Dynamic Analysis of Compressor Trips in the Snøhvit LNG Refrigerant Circuits 

      Schjølberg, Ingrid (Chapter, 2008)
      Compressors are key components in the refrigerant circuits of the Snøhvit LNG plant and contain large amounts of mechanical energy. Thus it is imperative that the control system is able to keep the compressor out of surge ...
    • Dynamic behaviour of a small-scale hydrogen reformer 

      Michelsen, Finn Are; Schjølberg, Ingrid; Lund, Berit Floor (Chapter, 2007)
      This paper explores dynamics for control design for a novel small-scale hydrogen reformer based on compacted plated heat exchanger technology. Reforming is seen as an important step towards the use of renewable fuels as ...
