The Use of Magnesium Hydroxide as a Cost Effective Cellulose Protector in the Pressurized Alkaline Peroxide (Eop) Bleaching Stage, 2004 Engineering, Pulping, and PCE&I Conference

PressWeb.jpg

Magnesium ion is an effective protector of cellulose against degradation in the pressurized alkaline peroxide (Eop) bleaching stage. Laboratory experiments and mill scale trials at the Western Pulp Squamish mill have successfully shown that application of magnesium hydroxide in the Eop stage provides a cost effective partial replacement of caustic soda and protection of cellulose from alkali degradation as compared to magnesium sulfate. There is no adverse impact on final pulp brightness or viscosity.
