METHOD OF PRODUCING CELLULOSE FOR CHEMICAL PROCESSING Russian patent published in 1999 - IPC

Abstract RU 2138590 C1

FIELD: paper-and-pulp industry. SUBSTANCE: wood cuttings are hydrolyzed by simultaneously feeding steam into bottom part of digester and withdrawing it from top part of digester. Hydrolyzate is discharged through turpentine-blowing valve until pressure 0.20-0.30 MPa is achieved, after which sulfate cooking is carried out. EFFECT: improved quality of product. 2 cl, 3 tbl, 5 ex
