  1. 21. Process Integration in Model Kraft Pulp Mills. Technical, Economic and Environmental Implications

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

    Sammanfattning : The technical and economic conditions for reducing the energy consumption cost-efficiently and thereby releasing a surplus of biomass fuel in the pulp and paper industry are changing. For example, new environmental restrictions increase the need for closed water loops and other system modifications, which can lead to increased opportunities for energy savings. LÄS MER

  3. 22. Decarbonization in Carbon-Intensive Industries - An Assessment Framework for Enhanced Early-Stage Identification of Optimal Decarbonization Pathways

    Författare :Tharun Roshan Kumar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon-intensive industries; Industrial decarbonization; Process integration; Cost estimation; CO2 Capture; Exergy and Pinch analyses; Process modeling;

    Sammanfattning : Carbon-intensive industries currently account for a quarter of global annual CO2 emissions. Achieving mandated climate targets necessitates the rapid implementation of decarbonization technologies in these industries. Such deployments typically involve substantial upfront investments amidst technical, economic, and policy uncertainties. LÄS MER

  4. 23. On the use of process integration methods : evaluation of energy and CO2 emission strategies in blast furnace ironmaking and oxygen steelmaking

    Författare :Christer Ryman; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : This work deals with sustainable resource utilisation in integrated (iron ore based) steelmaking, with special emphasis on how to analyse process adaptation and developments aiming towards lowering of the emission of greenhouse gases, in particular carbon dioxide (CO2), to the atmosphere. Climate change and management of CO2 are real issues for the steel industry these days. LÄS MER
