The Pulp and Paper Making Processes
THE PULP AND PAPER MILL Although there are several chemical and mechani-cal pulping methods used for delignifying wood (table 2-l), separating fibers, and removing discol-oration, all integrated pulp and paper mills involve the same general steps in the manufacture of pulp and paper. These steps include: 1 ) raw material
