Lignin is one of three polymers in wood and the one that has to be removed in the chemical pulping process to liberate the fibers that are used in cellulosic products, such as paper and cardboard. The extent to which lignin is removed is important for the control of this This method for the Determination of kappa Number was developed through cooperation with PAPRICAN. PAPRICAN developed equations, calculations and methods which were then developed to work with our hardware and software. kappa Number is the amount of potassium permanganate (KMnO4) consumed by 1 g of pulp.
