  2. 1. Through-Drying of Tissue Paper - Experiments and Modelling

    Author : Henrik Weineisen; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper drying; modelling; TAD; through-drying; through-air drying; tissue; paper;

    Abstract : In through-drying of paper, the energy required for drying is supplied by hot air, which is forced through the paper structure. The area for heat and mass transfer is the internal surface area of the paper, which is often many times larger than the external web surface area (xy-plane). READ MORE

  4. 2. Modelling of the pyrolysis of large wood particles

    Author : Michel Bellais; Krister Sjöström; Björn Zethraeus; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drying; modelling; pyrolysis; shrinkage; wood; Chemical energy engineering; Kemisk energiteknik;

    Abstract : Wood is an interesting alternative to fossil fuels. It is CO2-neutral and widely available. However it is a difficult fuel to handle which features a low energy content. Thus technologies for wood thermal conversion need to be improved. READ MORE

  5. 3. Drying kinetics, coalescence and agglomeration of dairy products particles

    Author : Loredana Malafronte; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; single particle; stickiness; agglomeration; spray drying; modelling; drying-kinetics; coalescence; dairy;

    Abstract : Spray drying is used in the food, pharmaceutical, and chemical industries for producing powder from a liquid feed. The unique advantages of spray drying are producing powders of a specific particle size and moisture content, handling heat sensitive products, and high capacity. However, spray drying is a complex process. READ MORE

  7. 5. Modelling of Mass and Heat Transport in Paper - Evaluation of Mechanisms and Shrinkage

    Author : Erik Baggerud; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solid-based coordinates; paper; porous medium; convection; diffusion; volume fractions; mercury displacement; shrinkage; simulations; convective; hot surface; Modelling; drying; Wood; pulp and paper technology; Pappers- och massateknik;

    Abstract : In this work a one-dimensional model for the mass and heat transport in the thickness direction of paper has been developed. Solid-based coordinates were applied to simplify incorporation of shrinkage. Liquid diffusion, gas convection and vapour and air diffusion were incorporated as mass transport mechansims. READ MORE
