  1. 1. Sodium Salt Scaling in Black Liquor Evaporators

    Författare :Mathias Gourdon; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sodium carbonate; black liquor; falling film evaporation; fouling; scaling; heat transfer; sodium sulfate;

    Sammanfattning : Sodium salt scaling has long been recognized as a problem in the recovery cycle of kraft pulp mills, especially in black liquor evaporators. In the black liquor evaporation, as the black liquor becomes more concentrated, the sodium salts, particularly sodium carbonate and sodium sulfate, will saturate and precipitate from the solution.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; electrochemical solid state cells; polymer electrolytes; sodium batteries; liquid electrolytes;

    Sammanfattning : Today lithium-ion batteries (LIBs) are dominating the field of rechargeable batteries for portable devices. More recently LIBs have also been considered for large-scale applications, such as in the areas of electromobility and grid storage. LÄS MER

  5. 5. Model for activity coefficients and solubilities of Na2CO3 and Na2SO4 in high-temperature solutions

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Marta Anna Bialik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scaling; Pitzer model; activity coefficient; solubility; sodium carbonate; sodium sulfate; boiling point raise; double salt; solid solution; burkeite;

    Sammanfattning : Scaling of sodium sulfate and sodium carbonate double salts has long been recognized as a problem in the black liquor evaporation process. These salts are abundant in black liquor and often tend to precipitate on heat transfer areas, thereby significantly decreasing the heat transfer efficiency. LÄS MER
