Application Of Pyrolysis Gc/ms In The Development Of A Chemical Retention And Stickies Control Program For A 100% Recycled Newsprint Mill

摘要

The optimization of the chemical program on two newsprint machines using 100% DIP at AbitibiBowater, Thorold is described. For the first time, retention of contaminants from recycled paper was optimized using pyrolysis GC/MS. We discuss factors affecting machine performance, detailed selection criteria, and laboratory techniques used to evaluate the wide spectrum of available programs in terms of fines and filler retention, drainage and contaminant control. The performance of the program developed in laboratory trials was verified with a paper machine trial.
