System Closure for Kraft Pulp Mill and the Latest Fiberline Technologies

摘要

The pulp and paper industry is always under strong pressure from authorities,"green" organizations and consumers to reduce the environmental impact of the pulping processes.Since the clioxin debate,the pulp industry had improved its operation and to reduce the emissions and other substances to the receiving waters with new technologies same as recycling the filtrate or system closure.In this paper it will be discussed that system closure for kraft pulp mill and the latest fiberline technologies.At the mention of system closure in kraft pulp manufacturing,it is the important developments include widespread adoption of new cooking techniques,oxygen delignification,closed screening,improved process control,new bleaching methods,and systems that minimize pulping liquor losses.It was shown that Kvaerner Pulping new technologies such as the new cooking processes COMPACT COOKING? and KOBUDO~(MARI)cooking systems,a new oxygen delignification system-DU-ALOX~TM,a hot chlorine dioxde bleaching system-DUALD~TM and a new washing equipment COMPACT PRESS~? are playing an important role in system closure.
