  • Corrosion control methods
    Patent number: 9290849
    Abstract: There are provided methods of suppressing corrosion of a corrodible metal surface that contacts a water stream in a water system, the method comprising: (a) introducing into the water stream a shot dose of a treatment composition comprising a corrosion inhibitor, the shot dose being introduced into the water stream over a first time period and the water stream having a first concentration of corrosion inhibitor during the first time period; (b) then reducing the amount of treatment composition that is introduced into the water stream; and (c) after the first time period, maintaining a second concentration of corrosion inhibitor in the water stream over a second time period, the second concentration being less than 25% of the concentration of corrosion inhibitor during the first time period.
