Green liquor is produced when chems. are recovered in the kraft pulp process. Industrially produced green liquor contains a solid, non-sol. phase known as 'green liquor dregs' which is removed either by filtration or sedimentation. The work presented in this paper compares the sepn. properties of green liquor produced in a gasifier unit with that produced in a recovery boiler. The two types of green liquors were found to have almost similar sepn. properties with respect to both sedimentation and filtration. In the case of filtration, the av. specific filtration resistance was around 1012 to 1013 m/kg at 1 bar filtration pressure.
