Severe corrosion has been encountered in fractionation columns at the solvent refined coal (SRC) pilot plants in Fort Lewis, Washington, and Wilsonville, Alabama, as well as at the H-Coal Pilot plant in Catlettsburg, Kentucky, and the Exxon Donor Solvent Pilot Plant in Baytown, Texas. Studies of this problem included exposure of coupons in the columns, analyses of liquids collected at the pilot plants, and laboratory experiments. This work specifies alloys with adequate corrosion resistance for construction of fractionation columns, identifies the chlorine-bearing compounds, and proposes chlorine transport and corrosion mechanisms. 14 refs.
