| Abstract: | Formation of sulfide and Chemical mechanism of its spontaneous combustion in oil tank are systematically studied referring to sulfide chemistry, electrochemistry and thermochemistry. The control technique for spontaneous combustion is critically explored. It is found that chemical and exothermic reaction, and heat accumulation are the condition of spontaneous combustion, while oxidation of the sulfide, accumulation of heat quantity, temperature elevation and ignition are the main course. The main measures for controlling the spontaneous combustion are to prevent the corrosion caused by sulfur, inhibit the oxidation reaction by sulfide, hasten the heat release and lower the temperature. The most efficient approach is electrochemical control technique. |
