Gibson Station is Duke Energy’s largest power plant. It is a five-unit facility that was built between 1976 and 1982. Unit 5 is co-owned by Wabash Valley Power Association and Indiana Municipal Power Agency. All five units have sulfur dioxide scrubbers.
Ferralium® 255 (plate) was used with notable success as the retrofit lining, ¼” thick, of horizontal absorber vessels. A wet magnesium-enhanced limestone flue gas scrubber was built to reduce SO2 emissions at the stack outlet to comply with federal regulations. The unit went into operation in 1982 with carbon steel absorber vessels lined with an inorganic calcium-alumino-silicate gunite type lining reinforced with a carbon steel wire mesh. Cracking and erosion of the lining resulted in the decision to replace the lining, and after an economic assessment it was decided to install a metal alloy liner. Ferralium® 255 (plate) was chosen on the basis of its mechanical properties, corrosion resistance and cost after testing of various alloys in racks installed in an absorber at the power station. After 3 years testing, there was no sign of pitting or erosion.
