OAE 11/15

ChemStone OAE 11/15 is a novel pulping additive that increases cooking liquor effectiveness and prevents overcooking to improve product yield and uniformity.

The unique patented chemistry in this additive increases alkali penetration by 30 percent within 15 minutes, but halts acid hydrolysis as soon as alkali is available. Dense woodchips are penetrated thoroughly, while fine cellulose and hemicellulose fibers are protected from over processing. Unwanted compounds are prevented from re-precipitating, and by-products are effectively eliminated from the fiber mixture. This easy-to-handle cooking aid is effective for both hardwood and softwood pulps and is applicable to all pulping processes, including Kraft, soda/AQ, green liquor semi-chemical, sulfite cooking, and CTMP.
