Lignin Dewatering Process
US Patent:
8613781, Dec 24, 2013
Filed:
Aug 8, 2008
Appl. No.:
12/189046
Inventors:
Harrison R. Cooper - Bountiful UT, US
International Classification:
C10L 5/00, D21C 11/00
US Classification:
44550, 162 16
Abstract:
A lignin plastics solids mass containing lignin solids and liquids with up to 85% liquids can be partially dewatered by heating the lignin plastics solids mass to above a critical temperature at which time the lignin plastics solids agglomerate into lower moisture granular solids with between about 45% to 55% liquids releasing excess liquid which can be easily removed from the solids. The process is particularly useful for lignin plastics solids removed from black liquor from paper mills, or for similar lignin plastics solids masses, which can contain up to 85% liquids and which need to be dried to form useful lignin solids, which can be used for example for fuel. The dewatering process can be combined with the process for separating the lignin from the black liquor to separate the dewatered lignin directly from the black liquor.
