    Author : Hans Magnusson; Ulf Germgård; Gunnar Henriksson; Hans Theliander; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; kraft pulping; recovery boiler; smelt properties; non-process elements; oxygen delignification; viscose manufacturing; integrated production; regenerated cellulose; sulfatmassa; fysikaliska egenskaper; smälta; sodapanna; processfrämmande ämnen; bioraffinaderi; integrerad produktion; regenererad cellulosa; Chemical Engineering; Kemiteknik;

    Abstract : Modern chemical technology is an efficient tool for solving problems, particularly within the complex environment of the pulp and paper industry, and the combination of experimental studies, mill data and mass balance calculations are of fundamental importance to the development of the industry. In this study various examples are presented, whereby chemical technology is of fundamental importance. READ MORE

  6. 4. System Aspects of Black Liquor Gasification – Consequences for both Industry and Society

    Author : Håkan Eriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; Black liquor gasification; Biomass; Combined Cycle; Eco cyclic pulp mill; CHP; Electricity production; Recovery boiler; Gas turbine;

    Abstract : The pulp and paper industry consumes large quantities of biofuels (mainly bark and black liquor) to satisfy process requirements. Biomass is however a limited resource, and biofuel usage should therefore be as effective as possible. READ MORE

  7. 5. Characterisation of Fuels and Fly Ashes from Co-Combustion of Biofuels and Waste Fuels in a Fluidised Bed Boiler. A Phosphorus and Alkali Perspective

    Author : Anita Pettersson; Högskolan i Borås; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; phosphorus recovery; co-combustion; fluidised bed combustion; olivine; Biofuels; zeolites; fertiliser; extraction; refuse derived fuels; kaolin; alkali; sulphur; ash; municipal sewage sludge;

    Abstract : In the efforts to create sustainable production of heat and power and to reduce the net CO2 emissions to the atmosphere, alternative fuels are today being utilised. These fuels are, for example, biofuels and waste derived fuels such as different residues from the agricultural sector and the pulp and paper industry, municipal sewage sludge and municipal sorted solid waste.
