Corrosion coupon studies at coal liquefaction pilot plants

As part of the Fossil Energy Materials Program at Oak Ridge National Laboratory, we have supplied corrosion coupons to coal-liquefaction pilot plants for exposure in selected vessels. These vessels were chosen on the basis of previous corrosion experience, anticipated corrosion behavior (especially important when operating conditions were changed), accessibility, and availability. Alloys exposed were selected to give a series with a corrosion resistance ranging from less than to greater than that thought to be needed for each application. Corrosion rates calculated from weight changes of the exposed coupons provide information useful in selecting materials for coal-liquefaction plants. The results presented are from coupons exposed in the Wilsonville, Alabama, and Fort Lewis, Washington, Solvent Refined Coal pilot plants; the Catlettsburg, Kentucky, H-Coal Pilot Plant; and the Baytown, Texas, Exxon Coal Liquefaction Pilot Plant.
