Abstract

Severe corrosion observed in fractionating columns at the Fort Lewis, Washington, and Wilsonville, Alabama, solvent refined coal pilot plants is most severe for materials exposed in the 230 to 250 C (446 to 482 F) range and results in corrosion rates of as much as 6. 4 mm/y (250 mpy) for AISI 18-8 stainless steels. Studies of this problem include exposure of coupons, analysis of failed components, chemical analysis of liquids and laboratory experiments. The corrosion mechanism is discussed.
