Lime Causticization Product Brightness Improvement Via Pre-Slaking

US Patent:
2013012, May 23, 2013
Filed:
Aug 19, 2011
Appl. No.:
13/812930
Inventors:
Joseph A. Sohara - Northampton PA, US
Keith Hanchett - Emmaus PA, US
David Peters - Bethlehem PA, US
Assignee:
Specialty Minerals (Michigan) Inc. - Bingham Farms MI
International Classification:
C01F 11/18
US Classification:
423432
Abstract:
A method for obtaining particulate calcium carbonate exhibiting improved brightness and color and having uniformity of size such that when the particles are formed in the causticization process in a kraft pulp mill, the time required to separate the particles from liquors in which they are suspended is minimized and the amount of liquor recovered is maximized, with minimal dilution by water used for washing. The method includes the steps of a) slaking calcium oxide in water or an alkaline liquor containing as dissolved species predominantly sodium hydroxide; b) mixing the slaked lime with green liquor from a kraft pulping process to complete a causticization reaction that produces white liquor and lime mud; c) separating the lime mud from the white liquor; and d) milling a portion of the lime mud for use as a white mineral pigment in applications where such pigments are typically used.
