Improved resistance to localized corrosion in FGD systems through alloy design

OSTI ID:6984005
One limiting step in the reliable operation of flue gas desulfurization (FGD) systems has been materials failure due to corrosion. The most common forms of corrosion encountered in various FGD system components are usually pitting or crevice corrosion. A practical solution to the corrosion problem is the use of the proper corrosion resistant alloy that is effective, performance wise and cost wise, for each specific component of the FGD system. Two new nickel-base alloys, HASTELLOY alloys C-22 and H, have been engineered, developed, and tested in the laboratory and in the field to verify their improved resistance to localized corrosive attack. The uniqueness of these alloys is their versatility and cost-effective performance for most components in FGD systems.
