影响石油污染物挥发行为的因素

进行了4种不同石油制品在不同温度时的挥发试验,并对其挥发量与挥发时间的关系进行了模拟,试验结果表明,柴油和煤油的挥发量与挥发时间呈二次多项式关系,而90#汽油的挥发量与挥发时间呈对数关系,混合芳烃的挥发量与挥发时间呈线性关系。柴油经过不同程度的挥发后,其物理性质如粘度和比重发生了改变,其中柴油粘度随着挥发而增加,并且柴油的粘度与挥发质量分数有很好的正相关性,相关系数为0.988。

Effects of factors on volatilization of petroleum contaminants

The volatilization tests of four different of petroleum products at different temperatures were conducted, and the relationship between the volatilization amount and the time were simulated. And the results indicated that diesel oil and kerosene evaporated in an quatric polynomial manner, where the loss of diesel amount were approximately quatric polynomial with time, 90# gasoline evaporated in a logarithmic with time, and the aromatic mixture volatilize at linear with time. The physical properties of diesel such as viscosity and density changed after the different content of volatilization, and the viscosity of diesel increased with the volatilization carried out. And there was positive relativity between the viscosity and the content of diesel oil volatilization, the correlation coefficient was 0.988.
