Abstract
For avoiding equipment fouling from metal sulfide deposition in the processing of cracked gases containing H.sub.2 S and CO, the reactive metal species capable of carbonyl formation are prevented from contacting equipment parts operating within a temperature range favoring the formation of metal carbonyls, e.g., 30.degree.-250.degree. C. To accomplish this, the cracked gas is subjected to solids separation to remove dust particles containing the reactive metal species, or the cracked gas is oxidized to inactivate the metal species. Cooling water is also subjected to a preceding step of removing the reactive metal species.
