  4. 2. Recovery of Kraft Black Liquor - Alternative Processes and System Analysis

    Author : Tobias Richards; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; shrinking-core; entropy; Kraft black liquor; equilibrium; thermodynamic efficiency; direct causticization;

    Abstract : Besides the conventional recovery process, there are several possible processes whereby the cooking chemicals in kraft black liquor can be recovered. A part of one of the possible processes, direct causticization using titanate, has been studied in detail. READ MORE

  5. 3. Recovery of kraft black liquor with direct causticization using titanates

    Author : Ingrid Nohlgren; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Abstract : The feasibility of direct causticization of kraft black liquor using titanates has been evaluated. This has been done by studying the kinetics of the reaction between sodium tri-titanate and sodium carbonate and describing the kinetics by appropriate reaction models. READ MORE

  6. 4. Lime Mud Reburning. Properties and Quality of the Lime Produced

    Author : Charlotta Hanson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : It is of utmost importance that the white liquor used in the digester of a sulphate pulp mill is of high quality. The white liquor is prepared in the causticizing plant, through causticizing of the sodium carbonate in the green liquor. READ MORE

  7. 5. Disintegration of Lime Mud Particles during the Causticizing Operation

    Author : Pia Tiljander; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CaCO3; Ca OH 2; CaO; lime mud; mixing; particles; slaking; causticizing; disintegration; impeller;

    Abstract : It is of essential importance that the white liquor used in processing wood chips to produce pulp in the sulphate pulp process is of high and uniform quality. The white liquor is, together with lime mud, produced in the causticizing plant where sodium carbonate is causticized with lime, slaked in green liquor. READ MORE
