In order to meet more stringent EPA guidelines the power industry must now build or retrofit their facilities with flue gas desulfurization (FGD) systems. A critical part of these systems is the FGD absorber. A common building material for the absorbers has been Duplex 2205 and 255 Alloys; however the 2205 Alloy is showing signs of premature corrosion throughout the industry. The root cause of this corrosion is still under investigation but with some absorbers lasting less than 18 months a repair regimen is sorely needed. This paper will discuss the issues surrounding 2205 Alloy corrosion as well as methods to rehabilitate and protect both old and new absorbers with Epoxy Vinyl Ester Polymer lining. The paper will also review the proper cleaning surface preparation application process and choice of Epoxy Vinyl Ester Polymer lining to protect 2205 Alloy and prevent its premature breakdown in this environment.
