Impregnation, vapor phase and methanol as means of intensifying the softwood kraft pulping process (Helsinki University of Technology)
ABSTRACT The objective of the research was to find ways to shorten the cooking time, i.e. intensify the kraft pulping process. The reason for undertaking such a study lies in the long standing trend of ever increasing reactor size in the kraft pulping industry. The huge digester size in use presently has lead to severe problems in understanding the behavior …
