  1. 1. Interception evaporation : processes and measurement techniques

    Författare :Angela Lundberg; Luleå tekniska universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : In temperate regions, evaporation of water intercepted by the vegetation represents an important part of the evapotranspiration. A review of interception evaporation studies showed that knowledge about interception evaporation processes is limited and progress is hampered by technical difficulties. LÄS MER

  3. 2. Detailed simulations of droplet evaporation

    Författare :Giandomenico Lupo; Christophe Duwig; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; droplet; evaporation; phase change; multicomponent; immersed boundary; droppe; förångning; fasövergång; multikomponent; nedsånkt rand;

    Sammanfattning : Droplet evaporation (and condensation) is one of the most common instancesof multiphase flow with phase change, encountered in nature as well as intechnical and industrial applications. Examples include falling rain drops, fogsand mists, aerosol applications like electronic cigarettes and inhalation drugdelivery, engineering applications like spray combustion, spray wet scrubbing orgas absorption, spray drying, flame spray pyrolysis.

  4. 3. Energy Efficient Evaporation in Future Kraft Pulp Mills

    Författare :Jessica Algehed; Chalmers University of Technology; []
    Nyckelord :process integration; black liquor; pulp and paper; pinch technology; wastewater; evaporation; excess heat; economics; energy;

    Sammanfattning : In the future, the technical and economic conditions for energy savings in the pulp and paper industry will change. More excess heat will be available in future mills above 80°C than in existing mills, increasing the potential for process integration, and governmental actions for reducing CO2 emissions and the deregulation of electricity markets will change the economic conditions for investments aimed at saving energy.

  5. 4. Heat Transfer and Hydrodynamics in Falling Film Evaporation of Black Liquor

    Författare :Miriam Johansson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; correlation; black liquor; turbulence; hydrodynamics; kraft pulp mill; falling film; Heat transfer; evaporation; experimental; evaporator;

    Sammanfattning : The evaporation plant is one of the major steam consumers in kraft pulp mills, which are the dominant type of chemical pulp mill in Sweden. Previous studies have shown potential to decrease the live steam demand for the pulp process, e.g. LÄS MER

  7. 5. Process modelling based on data from an evaporation and a CTMP process : Analysis of energy efficiency and process variability

    Författare :Daniel Ekbåge; Lars Nilsson; Helena Håkansson; Per Engstrand; Karlstads universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CTMP; process modelling; evaporation; energy efficiency; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : The manufacture of pulp and paper is an energy intensive process configured of several unit processes that shape a network of flows of wood chips, chemical pulp, mechanical pulp, paperboard, steam and other important components. Improved energy efficiency supports sustainability of the process and the products. LÄS MER
