  1. 6. 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 :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

  3. 7. Advances in droplet evaporation

    Författare :Giandomenico Lupo; Christophe Duwig; Sébastien Tanguy; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Droplet evaporation (and condensation) is one of the most common instances of multiphase flow with phase change, encountered in nature as well as in technical applications. Examples include falling rain drops, fogs and mists, aerosol applications like electronic cigarettes and inhalation drug delivery, and engineering applications like spray combustion, spray wet scrubbing or gas absorption, spray drying, flame spray pyrolysis.

  5. 9. Novel process integration opportunities in existing kraft pulp mills with low water consumtion

    Författare :Cecilia Bengtsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; excess heat; evaporation; pinch technology; pulp and paper; energy; system consequences; process integration;

    Sammanfattning : The economic opportunities for energy savings due to process integration of the evaporation plant have proven to be good in model mills with low water consumption. This is due to the fact that the temperature level of excess heat is higher compared with pulp mills with larger water consumption. LÄS MER

  7. 10. Probing the Precipitationshed : A quantification of the biophysical dimensions of terrestrial moisture recycling

    Författare :Patrick W. Keys; Line Gordon; Steve Lyon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; moisture recycling; precipitation; evaporation; variability; ecosystem services; naturresurshushållning; Natural Resources Management;

    Sammanfattning : Terrestrial moisture recycling is the phenomena whereby water evaporates from the land surface, travels through the atmosphere, and fall as precipitation downwind. The interaction of societies with this branch of the hydrological cycle, though critical to the productive functioning of ecosystems around the planet, remains poorly understood. LÄS MER
