  1. 1. Disturbances in Fixed-Bed Combustion

    Författare :Sven Hermansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; modelling; packed bed; bed; combustion; channelling; grate furnace;

    Sammanfattning : Conversion of solid fuels in fixed beds is a common method for heat and power production. A frequent fixed-bed technique in small to medium scale is combustion in grate furnaces. Grate furnaces are widely used in the industrial energy branch and appreciated for their stability and simplicity of control. LÄS MER

  3. 2. Numerical simulations of industrial-scale packed-bed adsorbers

    Författare :Adam Jareteg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Packed Bed; Numerical Modeling; Temperature Swing Adsorption; Finite Volume Method; Industrial Scale;

    Sammanfattning : A common technique for removing harmful substances, for either persons or equipment, from a stream is to use the phenomenon of adsorption. This technique is used in, for example, water purification, personal protection, chemical and pharmaceutical production and biomass gasification. LÄS MER

  4. 3. CALIBRATION OF CHROMATOGRAPHY MODELS

    Författare :Patrik Persson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; film mass transfer resistance; Kemiteknik och kemisk teknologi; sorption kinetics; external volume; monolithic bed; shallow bed; packed bed; capillary model; detailed model; computer simulation; parameter estimation; diffusion; model calibration; Chromatography; modelling; proteins; Chemical technology and engineering;

    Sammanfattning : AbstractThis thesis is devoted to calibration of mathematical chromatography models. Chromatography models include unknown parameters that must be determined before the models can be applied to optimization or scale-up of a chromatography process. LÄS MER

  5. 4. Packed-Fluidized Bed Reactors – Batch Experiments and Fundamental Modeling with Random Metal Packings

    Författare :Nasrin Nemati; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bubbling fluidized bed; Heat transfer; Confined fluidization; Chemical-looping combustion; Mass transfer; Random packing; Packed-fluidized bed;

    Sammanfattning : The aim of this work is to investigate the effect of random packings on heat and mass transfer phenomena, when applied in bubbling fluidized beds. For this purpose, first, the heat transfer coefficient to a horizontal tube submerged in a fluidized bed containing various types of random packings was investigated. LÄS MER
