Patent

CA 2144078

A conventional continuous digester is modified so as to provide a countercurrent cook throughout the entire height of the digester. Instead of connecting an upper mid-point extraction screen to a flash tank, that screen is closed off and extraction is provided at the top of the digester, utilizing an in-line drainer to remove some of the liquor and feed it to a flash tank. The liquor not removed recirculates through a pressure screen to an impregnation vessel, and then back to the digester. A cooling circulation is provided just below the top extraction. Valves are provided in the liquor discharged from the drainer and a conduit from the upper mid-point extraction which may be manipulated to return the digester to conventional operation, including the addition of white liquor to the bottom recirculation.
