A coil for preheating natural gas, placed in the flue of a primary reformer, collapsed due to the formation of a thick deposit on the inside which prevented heat transfer. It was found that the deposit consisted of ferrous oxide transported from a colder portion of the gas line by formation of iron carbonyl. Carbon monoxide was generated by the cleaning cycle of a thio compound removal unit.
