  • Mechanism and equilibrium modeling of aluminosilicate scaling in alkaline media

    Creator:
    Gasteiger, Hubert A.
    Abstract:
    Problems with aluminosilicate scales in pulp and paper recycle streams create an interest in the formation mechanism and the chemical equilibrium of aluminosilicates. Evaluating solubility data from a system containing Na⁺ CI⁻, and OH⁻ ions as well as aluminium and silicon compounds, allowed to elucidate the characteristics of the aluminosilicate...

  • Solubility of aluminosilicates in kraft green and white liquors

    Creator:
    Wannenmacher, P. Nick
    Abstract:
    The increasing occurrence of aluminosilicate caused complications in krafi pulp mills can be attributed to the closing of purge points and the expanded use of contaminated feedstocks and recycled fiber sources. An active purge of aluminum and silicon from the chemical recovery cycle must be undertaken in order to maintain...

  • Chemical equilibrium of nonprocess elements in the kraft recovery cycle

    Creator:
    Streisel, Robert C.
    Abstract:
    Non-process elements are present in all kraft recovery systems. Non-process elements are defined as those elements which are not essential to the chemical process, i.e., are neither active pulping chemicals (e.g., NaOH and Na₂S in the kraft process), nor compounds present as a result of incomplete conversion of makeup chemicals...
