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...

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...

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...

Abstract:: Parallel solutions for two classes of linear programs are presented. First we parallelized the two-phase revised simplex algorithm and showed that it is possible to get linear improvement in performance. The simplex algorithm is the best known algorithm for solving linear programs, and we claim our result is the best...

Creator:: Wilson, Kenneth P.
Abstract:: 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...
