  1. 1. Disintegration of Lime Mud Particles during the Causticizing Operation

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

    Sammanfattning : 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. LÄS MER

  3. 2. Frequency Analysis of Sampled-Data Systems Applied to a Lime Slaking Process

    Författare :Olof Lindgärde; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; periodic systems; intersample behavior; sampled-data system; lime slaking; multirate sampling; frequency analysis; tank reactor; product inhibited; modeling;

    Sammanfattning : Single-rate and multirate sampled-data (SD) systems as well as linear time periodic (LTP) systems with discrete jumps are analyzed in the frequency domain. The focus of the analysis is both on rejection of disturbances and on robust stability properties. LÄS MER

  4. 3. Bruk av kalk och sand ur ett hantverkligt perspektiv

    Författare :Jonny Eriksson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Eriksson method; mortar; lime putty; quenching methods; lime-kilns;

    Sammanfattning : Sweden has a thousand-year history of burning (calcinating) and slaking (hydrating) limestone to produce a binder for mortar and stucco. We can assume that the conditions for manufacturing such binders have varied from one part of the country to another. LÄS MER

  5. 4. Dusting in a lime kiln - Characterization of the material and unit operations

    Författare :Henric C O Dernegård; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; terminal velocity; Dusting lime kiln; fines; lime mud filter; ESP-dust; reactivity;

    Sammanfattning : The present thesis describes the background of, and gives some points of orientation for, the phenomenon of dusting in the burner zone of a lime kiln. The aim of this study is twofold: to increase knowledge of the factors that influence the degree of dusting and also to investigate the effect a dusting lime kiln has on the white liquor preparation process.

  7. 5. Lime Mud Reburning. Properties and Quality of the Lime Produced

    Författare :Charlotta Hanson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : 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. LÄS MER
