  • Chemical efficiency increase in papermaking process
    Patent number: 10876254
    Abstract: 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 laccase enzyme and 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.
    Type: Grant
    Filed: October 2, 2018
    Date of Patent: December 29, 2020
    Assignee: SOLENIS TECHNOLOGIES, L.P.
    Inventors: John C. Harrington, Mingxiang Luo, Davit E. Sharoyan, Sujan Singh
