  • 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.

  • Flue gas desulfurization system and method for performing flue gas desulfurization
    Patent number: 10814272
    Abstract: A flue gas desulfurization (FGD) system in which a buffering additive feed directly adds a buffering additive containing acetic acid to either the FGD sump or a stream of the system that is downstream of the sump. In a method for performing flue gas desulfurization, the buffering additive, containing acetic acid, is added to either the sump or the overflow. That is, the buffering additive is added to the FGD system separately from the alkaline feed slurry, which contains lime or limestone.
