Effect of pulp delignification degree on fiber line performance and bleaching effluent load

Effect of pulp delignification degree on fiber line performance and bleaching effluent load

Industrially made kraft pulps obtained by a modified cooking process may contain 60-75 mmol/kg of hexenuronic acids (HexAs), which represents 6-7.5 kappa units. HexAs do not react with oxygen and very little of it is actually removed across the oxygen delignification stage, causing low efficiencies...
