The Kentucky Energy Cabinet Laboratory (KECL) has, over a period of several years, investigated the corrosion and wear of materials of construction in oil shale retorting. The objective of the program was to develop an alloy performance database so that cost-effective materials of construction can be selected for plant designs. The KECL researchers conclude that 18-8 type alloys are needed for components exposed to gas and mist. For components exposed to interaction of erosion or abrasion with corrosion, wastage rates can be 10-20 times those under corrosion alone. These areas should probably be refractory or ceramic lined. Any metallic components (thermowells, etc.) will need to be protected by hard coatings or overlays. In condensate systems, the low alloys suffered extensive corrosive damage. Ferritic and stabilized austinitic stainless steels can be used to prevent stress corrosion cracking in these systems. 4 tables.
