    Abstract : Kraft lignin isolated by precipitation can be considered as being a valuable renewable source of energy and material. Removing lignin from black liquor is also advantageous as it decreases the load on the recovery boiler, which is usually the limiting factor in the production of kraft pulp. READ MORE
