  • Polymer dispersants and methods of use in a nuclear steam generator
    Patent number: 6430249
    Abstract: A novel high-purity polymer dispersant and sludge conditioner added to the feedwater entering the secondary side of a nuclear steam generator for minimizing the accumulation of metal-oxide deposits within the nuclear steam generator during the continuing operation of the generator is disclosed. The high-purity polymer is selected from a group consisting of acrylic acid polymer, methacrylic acid polymer, acrylate polymer, methacrylate polymer, copolymers, and terpolymers, acrylate/acrylamide copolymer, acrylate/methacrylate copolymer, terpolymers, and mixtures thereof. Methods of making and applying the polymer dispersant and sludge conditioner are described. Means for removing the metal oxides and polymer from the blowdown stream are disclosed.
    Type: Grant
    Filed: March 16, 2001
    Date of Patent: August 6, 2002
    Assignees: Commonwealth Edison Company, BetzDearborn, Inc.
    Inventors: Phillip M. Egerbrecht, Joseph D. Bates, John A. Kelly, James D. Haff, Ralph Minnis
