  • METHOD OF OFFLINE CLEANING OF COOLING SYSTEMS
    Publication number: 20240393069
    Abstract: Methods for reducing an amount of calcium carbonate deposited on a surface of an offline condenser in a cooling system of a nuclear power plant, which include filling the offline condenser with a mixture comprising water and acetic acid and pumping the mixture through the offline condenser so as to contact the deposited calcium carbonate with the acetic acid. An amount of the acetic acid in the mixture is 1 to 25 wt %, and a temperature of the mixture is in a range of 10 to 50° C.

  • Methods and systems for calcite removal using polysuccinimide
    Patent number: 11230484
    Abstract: Methods and systems are provided for removing calcite deposits by contacting polysuccinimide with water to dissolve the polysuccinimide and supplying the dissolved polysuccinimide to surfaces fouled with the calcite deposits. The pH of the water that dissolves the polysuccinimide can be adjusted based on the amount of calcium in the water. Adjusting the pH will affect the dissolution rate of the polysuccinimide in water and the rate of removal of the calcite deposits.
