    • Colloidal Wood Resin: Analyses and Interactions 

      Mosbye, John Erlend (Dr. ingeniøravhandling, 0809-103X; 2003:63, Doctoral thesis, 2003)
      This thesis presents studies of the interactions between suspended particles and dissolved and colloidal substances (DCS) in process water. The main focus has been to determine if colloidal wood resin is adsorbed by suspended ...

    • Control of Fuel Cells 

      Zenith, Federico (Doktoravhandlinger ved NTNU, 1503-8181; 2007:65, Doctoral thesis, 2007)
      This thesis deals with control of fuel cells, focusing on high-temperature proton-exchange-membrane fuel cells. Fuel cells are devices that convert the chemical energy of hydrogen, methanol or other chemical compounds ...

    • Controllability analysis for process and control system design 

      Faanes, Audun (Dr. ingeniøravhandling, 0809-103X; 2003:76, Doctoral thesis, 2003)
      Controllability is the ability of a process to achieve acceptable performance, and in this thesis we use controllability analysis in the design of buffer tanks, feedforward controllers, and multivariable controllers such ...

    • Degradation- and Passage Kinetics of Concentrate Particles and Solubles in the Rumen 

      Olaisen, Vidar (Dr.ingeniøravhandling, 0809-103X; 2001:107, Doctoral thesis, 2001)
      This thesis deals with three actual issues of ruminant degradation and escape of dietary components: One of the main emphasis has been on how particle size distribution of concentrated feed affects the degradation and ...

    • Development and modification of glass membranes for aggreessive gas separations 

      Lindbråthen, Arne (Doktoravhandlinger ved NTNU, 1503-8181; 2005:24, Doctoral thesis, 2005)
      Chlorine as a chemical is widespread in industry and found in a great variety of processes ranging from water purification to plastic production. In this thesis, a magnesium production factory was chosen as an example ...

    • Mass Transport and Kinetic Phenomena in Catalytic Polymerization of Olefins 

      Kittilsen, Pål (Dr. ingeniøravhandling, 0809-103X; 2001:32, Doctoral thesis, 2001)

    • Minimum Energy Requirements in Complex Distillation Arrangements 

      Halvorsen, Ivar Johan (Dr. ingeniøravhandling, 0809-103X; 2001:43, Doctoral thesis, 2001)
      Distillation is the most widely used industrial separation technology and distillation units are responsible for a significant part of the total heat consumption in the world’s process industry. In this work we focus on ...

    • Sorption-enhanced steam methane reforming in fluidized bed reactors 

      Johnsen, Kim (Doktoravhandlinger ved NTNU, 1503-8181; 2006:116, Doctoral thesis, 2006)
      Hydrogen is considered to be an important potential energy carrier; however, its advantages are unlikely to be realized unless efficient means can be found to produce it without generation of CO2. Sorption-enhanced steam ...

    • Ultrafiltration of Partially Degraded Starch Solution 

      Demessie, Berhanu (Dr.ingeniøravhandling, 0809-103X; 2002:87, Doctoral thesis, 2002)
      Desizing wastewater is largely responsible for the chemical oxygen demand (COD) load in the textile industry wastewater. A larger portion of COD comes from degraded starch in desizing wastewater. Removing the starch from ...
