The separation of green liquor sludge: A comparison between liquors produced in a gasifier and a recovery boiler
University of Borås, School of Engineering.
2009 (English)Conference paper, Poster (with or without abstract) (Other academic)
Abstract [en]

Green liquor is produced as when chemicals are recovered in the kraft pulp process. The industrial formed green liquor contains a solid, non-solvable phase, called green liquor dregs and are removed either by filtration, or by sedimentation. This work compares separation properties of green liquor produced in a gasifier unit with green liquor produced in a recovery boiler. The two types of green liquors were found to have almost similar separation properties with respect to both sedimentation and filtration. For filtration, the average specific filtration resistance was about 1012 m/kg at 1 bar filtration pressure.
