Method for mitigation of caustic corrosion in coordinated phosphate/ph treatment programs for boilers |
摘要 |
The present invention utilizes low volatility amines or alkanol amines to control caustic corrosion which can take place when a boiler system, treated with a coordinated phosphate/pH program, is "out of control". N-substituted hydroxyalkyl piperazines are also capable of mitigating caustic corrosion in coordinated phosphate/pH programs. Combinations of the compounds of the present invention and phosphate have also been shown to be efficacious at mitigating caustic corrosion in coordinated phosphate/pH programs.
