摘要
阐明了原油储罐中硫化亚铁主要来源于硫化氢等腐蚀性气体直接与金属作用,产生的腐蚀产物及硫化氢与铁锈的反应产物。硫化亚铁最主要的危害是其自燃引起火灾,呼吸阀外腔内的硫化亚铁危害最大。分析了原油储罐中硫化亚铁的自燃过程,提出了硫化亚铁自燃事故的预防措施。
It is pointed out that iron sulfide in the crude oil storage tanks is proclueed 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.
