Patent
·
OSTI ID:6838820
A batch process to produce kraft pulp is described, in which a combination of black and white liquor is used for cooking of wood chips. In the process, the steam consumption to produce 357 tons/day pulp at 50% yield was approximately 1600 lb/ton pulp, compared with 4000 lb/ton for a batch digester of conventional type.
