Creator:: Thulstrup, Niels, 1970-
Abstract:: Production of dry particles made of titanium dioxide powder and black liquor is the first step in a newly proposed black liquor treatment process (Frederick et. al., 1992). This work investigates the granulation processes in a fluidized bed granulator of titanium dioxide and black liquor. Experiments are performed in a...

Creator:: Fang, Yi-Pygn
Abstract:: Douglas-fir wood chips from Oregon were pulped with kraft green liquor to produce semi-chemical pulps with properties suitable for the manufacture of corrugating medium. The effects of five cooking variables were studied, chemical charge, chip size, bark content of chips, pulping temperature, and liquor sulfidity. The combinations of levels of...

Creator:: Dutta, Tapas
Abstract:: Several additives have been used in research and on an industrial scale to improve the pulp yield and to increase the rate of delignification. One such additive is 1,4- dihydro- 9,10-dihydroxyanthracene (DDA), also called soluble anthraquinone. This chemical is widely used in Japan and some other countries, especially with the...

Creator:: Medhora, Hiraz Kekobad
Abstract:: A survey of the pulping literature indicated that although the kinetics of the Kraft Pulping process has been studied in detail , very few studies have been reported for Alkaline Sulfite / Anthraquinone (ASAQ) pulping process. There is no existing rate model for this pulping process. Hence, the objectives of...

Creator:: Techakijkajorn, Udom
Abstract:: Fume, sub-micron aerosal particles in the combustion gases, have been identified as a cause of extensive plugging and fouling in the heat transfer section of a kraft recovery boiler in kraft pulp mills. After the deposition on the heat transfer surface, fume deposits will undergo the sintering process which causes...
