摘要：
The development of the (CD) (EO) (D/E/D) simplified bleach sequence from the laboratory to the first commercial application in 1988 at the La Tuque mill is described. The implementation of this simplified sequence in the 50-Fibre sawdust bleachery has resulted in a large improvement in brightness stability as well as increased pulp strength. An important discovery was that the (D/E/D) stages, which were originally designed for processing well-chlorinated pulp, have been found capable of bleaching pulps chlorinated at low Kappa factors.
