Corrosion in four direct coal liquefaction pilot plants has been monitored by means of corrosion coupons and U-bend specimens. Vessels in which samples were exposed were selected on the basis of anticipated severity of corrosion and the availability and accessibility of exposure sites. Alloys were chosen so that the corrosion resistance of the series of alloys exposed at a site ranged from less resistant to more resistant than was considered necessary for that site’s environment. Calculated corrosion rates for samples provided by Oak Ridge National Laboratory (ORNL) are presented and compared with results obtained by others.
