Black liquor recovery boilers experience significant fire-side fouling problems due to the deposition of entrained particulate matter. Increased understanding of the mechanisms by which particles deposit on these surfaces will lead to more effective management of the resultant problems. There is some evidence which suggests that the sub-micron fraction of...
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...
This work is part of a larger project dealing with
nonprocess element (NPE) behaviour in chemical pulping
processes. Nonprocess 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...
