摘要
油品在储存、收发过程中,对它们的物性参数进行测定是必备的环节。根据原油蒸气压参比法测定原理,改进了油品蒸气压的测定方法。实测了多种油品的饱和蒸气压、摩尔质量及标准密度数据,重点讨论了油品蒸气压-温度的关系,拟合回归出该关系式。讨论了不同类型油品的蒸发损耗率及其变化值,阐述了油品参数在油气排放评估中的应用价值。
During the process of petroleum storage and transportation,to accurately measure the vapor pressure,molar mass,density and other physical parameters of petroleum products is an essential link.Based on crude oil-determination principle of saturated vapor pressure—reference method,petroleum products-determination of vapor pressure had been improved.The measured data of saturated vapor pressure,molar mass and standard density of various petroleum products had been offered.The relation between saturated vapor pressure of petroleum products and temperature was the focus,whose regression formula had been fitted.Based on the formula of evaporation loss and actual measurement,the evaporation loss ratio of different petroleum products and its change had been discussed,and the application value of physical parameters in the evaluation of vapor emissions had been expounded.
