Title:
METHOD OF DEWATERING THIN STILLAGE PROCESSING STREAMS
Document Type and Number:
WIPO Patent Application WO2006017048
Kind Code:
A3
Abstract:
A method dewatering thin stillage process streams generated in the processing of grain to ethanol comprising adding to the process streams an effective coagulating and flocculating amount of an anionic copolymer comprising acrylic acid sodium salt, methacrylic acid sodium salt or 2-acrylamido-2-methyl-l-propanesulfonic acid sodium salt to form a mixture of water and coagulated and flocculated solids; and separating the water from the coagulated and flocculated solids using a dewatering device.
