This report contains a summary of three separate continuous flow tests conducted on Pacific and Kumamoto oysters following a series of preliminary spent sulfite liquor (SSL) bioassays in 1958.
Black liquor gasification is one of the promising alternatives to
eliminate the drawbacks of the conventional recovery unit of the
kraft process. A numerical model has been developed to simulate an
industrial pilot scale entrained-flow gasifier currently operating at
Tampere, Finland. The objective of the model is to investigate the...
The kraft and kraft-anthraquinone pulping processes were used
for pulping Douglas-fir chips at 170°C, 180°C and 190°C temperatures.
Anthraquinone was added to the pulping liquor at two levels, 0.1%
and 0.2% based on wood, to study its effect on pulp delignification
at the three temperatures. The fluorescent behaviors of kraft...
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...
An important by-product of the kraft pulping process, black liquor is currently used in most pulp mills to produce steam in a recovery boiler. Two important black liquor characteristics are viscosity and burning (firing) characteristics, which determine the operating efficiency of the recovery boiler. Kraft black liquor is a complicated...
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...
