    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

  4. 2. Sintering in the Kraft Pulp Mill - Studies in the Rotary Kiln and Recovery Boiler

    Author : Josefina Lindblom; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sintering; recovery boiler dust; recovery boiler; solid state diffusion; rotary kiln; lime mud; lime; sintering model; specific surface area;

    Abstract : The conversion of black liquor to white liquor is carried out in the chemical recovery system, which is made up of several units; in two of them, i.e. the recovery boiler and the rotary kiln, sintering plays an important role. READ MORE

  6. 4. 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

  7. 5. Recovery of kraft black liquor using the titanate process : kinetics of the direct causticization reaction between sodium tri-titanate and sodium carbonate

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

    Abstract : The solid state reaction between sodium tri-titanate and sodium carbonate, forming mainly sodium penta-titanate, was investigated. Experiments were carried out in a micro-differential reactor made of quartz glass at various temperatures between 800°C and 880°C and in a pilot fluidized bed reactor operated in a semi-batch mode.
