Improving Degree of Delignification and Selectivity of Oxygen Delignification of Southern Pine Kraft Pulp [PDF]
, 2022 Oxygen delignification is a pre-bleaching stage that provides environmental benefits for bleached pulp production by replacing about 50% of the chlorine-based bleaching chemicals with oxygen. The resulting reduction in chlorine-based chemicals leads to a
