  • Patent number: 10144663
    Abstract: Hydrophobically modified Si-containing polyamines are useful for treating scale in industrial process streams. Preferred hydrophobically modified Si-containing polyamines are particularly useful for treating aluminosilicate scale in difficult-to-treat industrial process streams, such as in the Bayer alumina process streams, nuclear waste streams and kraft paper mill effluent streams.
    Type: Grant
    Filed: December 7, 2015
    Date of Patent: December 4, 2018
    Assignee: Cytec Technology Corp.

  • Patent number: 8119743
    Abstract: Materials and methods are provided whereby polymers with least 0.5 mole % of the pendant group or end group containing —Si(OR?)3 are used to control aluminosilicate scaling in an industrial process having an alkaline process stream such as a pulping mill process stream or a high level nuclear waste processing plant. When materials of the present invention are added to the alkaline process stream, they reduce and even completely prevent formation of aluminosilicate scale on equipment surfaces such as evaporator walls and heating surfaces. The present materials are effective at treatment concentrations that make them economically practical.
