GREEN LIQUOR RECOVERY FROM GREEN LIQUOR MUD PRODUCED THROUGH KRAFT PROCESS

摘要

PURPOSE: To enhance green liquor recovery rate by enhancing the concentration rate for the solid content of green liquor mud in a kraft process cooking chemical liquor recovering method. ;CONSTITUTION: Green liquor mud discharged from the bottom of a green liquor clarifier is fed to a continuous vacuum filtration-type concentrator or centrifugal precipitation-type concentrator where the green liquor mud is concentrated to a solid concentration of 10-35wt.%, and the resulting green liquor mud is fed to a pressing-type concentrator where the mud is concentrated to a solid concentration of 45-65wt.%.;COPYRIGHT: (C)1993,JPO&Japio
