Abstract
The four major operating coal liquefaction pilot plants in the United States have all experienced corrosion rates of carbon steel and 18-8 (Ni-Cr) stainless steels as high as 25 and 6. 4 mm/year, respectively. Severity is related to the chlorine content of the coals and operating temperature of the columns. Analyses identified several chlorine compounds that caused corrosion. The authors propose corrodant transport and mechanisms and suggest process changes to remove the corrodant.
