含硫油品储罐自燃影响因素的试验研究
|
摘要
为深入拓展研究含硫油品储罐自燃的影响因素,选择硫腐蚀产物混合物粒径、油污、含水率和硫化亚铁与硫化铁的质量比4个因素进行单因素试验,测定氧化增重率;基于正交试验验证4个因素相互作用的影响程度,采用极差分析和方差分析方法处理试验数据。结果表明:硫腐蚀产物混合物粒径、油污、含水率和硫铁化合物质量比等4个因素是影响其自燃的重要因素,且单因素影响的重要程度依次为硫铁化合物质量比、油污、粒径、含水率;交互作用中较为重要的是硫铁化合物质量比和油污的交互作用以及水分和油污的交互作用,其余交互作用可忽略。
In order to further study factors influencing spontaneous combustion of oil containing sulfur storage tanks,firstly,four factors including particle size,oil stain,water content and ferric iron compound mass ratio were selected for single-factor experiments to determine the oxidative weight gain rate. And then,based on the orthogonal experiment to verify the influence degree of the interaction between these four factors,the method of range analysis and the method of variance analysis were used to calculate the experimental data. The results show that sulfur corrosion products' particle size,oil stain,water content and mass ratio of ferrous sulfide to ferric sulfide are all important; and the order of importance of single factor influence is the mass ratio,oil stain,particle size and water content,and that the interaction between the mass ratio and oil stain and the interaction between water content and oil stain need to be considered,and the remaining interactions may not be considered.
