There have been several reports about the impact of Hot Water Extraction (HWE) of Northern Hardwoods on pulping with modest references to the impacts of HWE on the bleachabilty of the Kraft pulp produced from HWE extracted chips in a conventional ODED sequence. Mixed northern hardwood chips were extracted with water to achieve a range of mass removal in a simulated counter current mode. It was documented that the extracted chips required a significantly lower H-factor to achieve the same degree of delignification (kappa number) in a Kraft cook compared to control (unextracted chips) at the same AA charge.
