Title: Formation of Iron Sulphides in Oil Tanks with Sulfur and Its Oxidation Tendency
Abstract: Thermal oxidation of the iron sulphides is regarded as the main cause of tank fire and explosion accidents. Iron sulphides generate when Fe2O3, Fe3O4 and Fe(OH)3 as a predominant corrosion product in storage tank reacts with hygrogen sulphide, and hydrogen sulphide dissolving in form hydrosulphuric acid reacts with iron to give iron sulfides.The oxidation tendency of iron sulfides which generated from different mode are inspected, and the sulfurization are researched by electron microscope. The research results indicated the oxidation tendency of iron sulfides of Fe2O3,Fe3O4 is higer than others. The structure are various in their composition ,which may lead to different pyprophoricity.
