  • METHOD OF DEWATERING THIN STILLAGE PROCESSING STREAMS
    Publication number: 20070210007
    Abstract: A method dewatering thin stillage process streams generated in the processing of grain to ethanol comprising adding to the process streams an effective flocculating amount of an anionic copolymer comprising acrylic acid sodium salt, methacrylic acid sodium salt or 2-acrylamido-2-methyl-1-propanesulfonic acid sodium salt to form a mixture of water and flocculated solids; and separating the water from the flocculated solids using a dewatering device.
    Type: Application
    Filed: December 15, 2006
    Publication date: September 13, 2007
    Inventors: David Scheimann, Angela Kowalski
  • Method of dewatering thin stillage processing streams
    Publication number: 20060006116
    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-1-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.
