Mô tả: Any modifications to the bleach line layout should maintain the goal of high brightness per consumer demands. Two main areas of discussion stem from this line of thinking: 1. technologies currently applied or suitable for inclusion in a bleaching sequence based on prior mill experiences, and 2. technologies still on the drawing board or in laboratories. The current tendency indicates the elimination of chlorine from the bleach cycle and possibly the total elimination of chlorine dioxide in the future. A combination of oxygen delignification, ozone, peroxide, high-pressure oxygen extraction, and hydrosulfate use may offer the best potential for eliminating elemental chlorine.
