1. 16. On the determination and application of local filtration properties

   Författare :Peter Sedin; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

   Sammanfattning : Filtration is a mechanical unit-operation used for the separation of liquid and solid. In this work, the three sub-operations cake build-up, expression and washing have been studied. One difficulty often encountered in the design of filtration equipment is that the materials being filtered form more or less compressible filter cakes. LÄS MER

3. 17. Chromatographic separation of wood constituents

   Författare :Niklas Westerberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; mathematical modelling.; Norway spruce; separation; chromatography;

   Sammanfattning : In a modern kraft pulp mill only about 45 % of the incoming wood is present in the pulp and it is mainly composed of cellulose. The remainder of the wood, which is dissolved in order to liberate the cellulose fibres, e.g., hemicellulose and lignin, ends up in the mill´s recovery boiler to recover the latent energy. LÄS MER

4. 18. A Chemometric Approach to Process Monitoring and Control - With Applications to Wastewater Treatment Operation

   Sammanfattning : In this work, various aspects of multivariate monitoring and control of wastewater treatment operation are discussed. A number of important difficulties face operators and process engineers when handling online measurements from wastewater treatment processes. LÄS MER

5. 19. Modeling the microstructural evolution during hot working of C-Mn and Nb microalloyed steels using a physically based model

   Författare :Linda Lissel; Stefan Jonsson; Bertil Ahlblom; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; austenite; modeling; hot deformation; microstructure evolution; static recrystallization; dynamic recrystallization; metadynamic recrystallization; Other materials science; Övrig teknisk materialvetenskap;

   Sammanfattning : Recrystallization kinetics, during and after hot deformation, has been investigated for decades. From these investigations several equations have been derived for describing it. The equations are often empirical or semi-empirical, i.e. LÄS MER
