  • Antiscale dispersant composition and use thereof
    Patent number: 11760672
    Abstract: The present disclosure relates to antiscale dispersant compositions. The compositions may include various components. The compositions may be used in connection with gray and/or black water processing in a coal gasification system. The compositions are useful for inhibiting the deposition of various materials, such as calcium carbonate, calcium phosphate, iron, aluminum, silicate, calcium sulfate, and any suspended solids in the water.
    Type: Grant
    Filed: September 23, 2016
    Date of Patent: September 19, 2023
    Assignee: ECOLAB USA Inc.
    Inventors: Ling Feng Han, Yin Yin Tong, Fan Yang, Chun Bo Yu
  • Use of an inorganic salt or acid in reducing the hardness and/or alkalinity of a water system
    Patent number: 10889518
    Abstract: The present invention provides a use of an inorganic salt or acid capable of producing free phosphate or fluoride ion in reducing the hardness and/or alkalinity of a water system containing residual antiscalant. In the lab test, it is found that the addition of a suitable amount of sodium phosphate or sodium fluoride may induce alkalinity reduction as well as hardness reduction. The production efficiency can be enhanced since the scaling was relieved and heat exchange efficiency can be improved. Meanwhile, lower scaling stress also means lower antiscalant dosage and cost, and thus the total operation cost can be reduced.
