Abstract
Today. the Japanese Pulp and Paper Industry is facing more stringent regulations on chloroform emission. Therefore. most of the pulp mills are looking for a way of decreasing chloroform emission formed during their conventional pulp bleaching. It is well known that chloroform is mainly generated during the hypochlorite stage. With this background. it was decided, in this first part, to modify the existing bleaching sequence O C/D Ep H D used in a Japanese pulp mill to eliminate the H stage. The second part deals with the total replacement of Cl2 by ClO2 in order to prepare the Japanese pulp mills to the ECF bleaching considered in many other countries as the Best Available Technology (BAT). Finally the last optimization steps concerned the modification of the conventional oxygen delignification stage and the change of the operating conditions during the final D stage.
