  1. 1. Sodium Salt Scaling in Black Liquor Evaporators

    Författare :Mathias Gourdon; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; 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.

    Sammanfattning : Dopamine (DA) has been shown to act as an intrarenal natriuretic hormone and defects in the renal DA system have been associated with some forms of hypertension. How the DA activity is upregulated durin- increased sodium intake is, however, unknown. LÄS MER

  5. 5. Realization of Sodium-ion Batteries : From Electrode to Electrolyte Materials

    Sammanfattning : Batteries are among the most important technologies required to enable the world to move beyond fossil fuels towards a more efficient and environmentally friendly society based on electricity from renewable sources. Unfortunately, the rapidly increasing number and size of batteries that the world needs in order to perform this paradigm shift is putting enormous strain on the supply of traditional raw materials for batteries, such as lithium and cobalt.
