  1. 1. Sludge from pulp and paper mills for biogas production : Strategies to improve energy performance in wastewater treatment and sludge management

    Författare :Alina Hagelqvist; Thomas Nilsson; Karin M. Granström; Bengt Månsson; Bo Mattiasson; Thomas Welander; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anaerobic digestion; pulp and paper mill sludge; methane production; energy efficient sludge management; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : The production of pulp and paper is associated with the generation of large quantities of wastewater that has to be purified to avoid severe pollution of the environment. Wastewater purification in pulp and paper mills combines sedimentation, biological treatment, chemical precipitation, flotation and anaerobic treatment, and the specific combination of techniques is determined by the local conditions.

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Paniksyndrom; Kognitiv beteendeterapi KBT ; Psykodynamisk terapi PDT ; Arbetsförmåga; Termination setback; Panic Disorder; Cognitive Behavioural Therapy CBT ; Psychodynamic Therapy PDT ; Work Ability; Termination Setback;

    Sammanfattning : Approximately 2-3% of adults in Sweden will experience unexpected panic attacks that cause them to develop fears of future attacks and to alter their lives, defined as Panic Disorder with or without Agoraphobia (PD/A). The condition often onsets in late adolescence or early adulthood, with high levels of psychiatric comorbidity, social difficulties, diminished study and work ability, an elevated risk for substance use, health problems, and mortality.

  4. 4. Modelling and Simulation of Thermal Radiation in Biomass Combustion

    Författare :Thomas Nilsson; Förbränningsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat load; gas turbine; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; porous media; fixed bed; biomass; wood; FG-DVC; combustion; DOM; P1-approximation; Mie theory; RDG-PFA; EWBM; thermal radiation; soot;

    Sammanfattning : This thesis presents numerical investigations and simulations of fixed bed combustion of wood, models for predicting thermal radiative properties of particles and gases related to the combustion of wood, and a review of heat load calculations in gas turbines. All subjects have a common factor in thermal radiation. LÄS MER
