To control costs, designers must take advantage of a new generation of reduced cost, corrosion-resistant alloys. In the 1970’s when construction of wet FGD systems began, it was determined that very resistant material were required to prevent equipment failure due to corrosion

Carbon Dioxide Corrosion - an overview | ScienceDirect

Corrosion by wet carbon dioxide corrosion can result in high corrosion rates, but a carbonate film gives some protection and is more protective at higher temperatures. The carbon dioxide content is often not very high in refinery streams, except in hydrogen reformer plant systems.Corrosion and anticorrosion of wet limestone-gypsum,Download Citation | Corrosion and anticorrosion of wet limestone-gypsum flue gas desulfurization system | As the limestone scrubbing process is widely used in flue gas desulfurization(FGD) system,The Corrosion of Limestone Objects Due to Sulphuric,The acid occurs in the air in the form of Sulfuric acid mists responsible for the corrosion of various metallic and limestone-rich objects. Usually, acid rain results when air containing traces of sulfur dioxide mixes with water (Revie et al., 2011). The acid rain, owing to its PH leads to the corrosion of monuments statues plus memorial, whose main component is calcium carbonate

Halides The addition of halides, principally chlorides and fluorides, to acidic media can greatly increase their corrosivity. Halides can enter FGD systems via limestone and coal. In closed loop systems regeneration of the spent slurry can concentrate the halides. Halide levels over 100,000 ppm,
