  • The conversion of a kraft linerboard machine
    under alkaline conditions has superior properties to the conventional acid board. In addition to quality improvements there is the potential to reduce the fibre costs by loading with calcium carbonate and reducing the virgin fibre content. In terms of strength properties it is known that an increase
  • The conversion
    with calcium carbonate and reducing the virgin fibre content. In terms of strength properties it is known that an increase in pH will assist with refining due to fibre swelling and the improvements in refining will result in better fibrillation and improved fibre to fibre bonding. The increase in refining
  • Use of OWL (T)
    Factor" which is defined as Cl/(Na+K) in the ESP catch divided by Cl/(Na+K) in the virgin black liquor (molar basis). This value ranges from 1.5 to about 2.5 [4]. Similarly, there is a potassium enrichment factor "KEF", K/(Na+K). This value typically ranges between 1.2 and 2.0 reflecting
