METHOD OF INCREASING EFFICIENCY OF CHEMICAL ADDITIVES IN PAPERMAKING SYSTEMS

METHOD OF INCREASING EFFICIENCY OF CHEMICAL ADDITIVES IN PAPERMAKING SYSTEMS

A method of increasing chemical efficiency of chemical additives in a papermaking system includes the steps of providing thick stock pulp comprising soluble lignin, process water, and at least about 2% by weight of cellulosic fiber based on total weight of thick stock pulp, and adding at least one o...

description A method of increasing chemical efficiency of chemical additives in a papermaking system includes the steps of providing thick stock pulp comprising soluble lignin, process water, and at least about 2% by weight of cellulosic fiber based on total weight of thick stock pulp, and adding at least one organic polymer to the thick stock pulp to reduce the amount of soluble lignin therein. The organic polymer is chosen from cationic polymers, non-ionic polymers and combinations thereof.
