Harm Fulness and Preventive Measure of FeS in Oil Storage and Transportion Process

It is pointed out that iron sulfide in the crude oil storage tanks is procluced by directly interaction hydrogen sulfide and other corrosive gases with the metal and reaction between hydrogen sulfide and rust. The greatest hazard of ferrous sulfide is its spontaneous combustion resulting in fire, and ferrous sulfide in the external cavity of breathing valves has the greatest harmfulness. The process of the spontaneous combustion of ferrous sulfide in oil tanks is analyzed, and some prevention measures are proposed.
