摘要：

Metso Paper has developed modern kraft pulping technology in which COMPACT COOKING™ G 2 cooking system, pressure diffuser (PDW), Delta Knotter™, Delta Screen™, Twin Roll Press ™, oxygen delignification stage -OxyTrac™, and high consistency ozone bleaching stage-ZeTrac™, etc. are included. With Metso's modern kraft pulping technology it can be fully meet the requirement for a fiberline with huge capacity up to 5, 000 ADt/day, homogenous cooking with the mixed chips, increasing pulp yield. And it can reduce water and energy consumption, minimize discharge of filtrate which is related to decrease the environmental load. Moreover, it can also be easy to convert the bleaching plant from element chlorine free bleaching (ECF) to total chlorine free bleaching (TCF). With installation of Ze Trac™ stage it will be easy to recover a part of filtrate from the bleaching plant, and change bleaching plant to total effluent free bleaching (TEF) when development of a suitable way to minimize the problem of accumulation of non-process elements in the system in the future.
