密度法指导沥青预处理工艺循环溶剂回配的方法

The density method is used to guide solvent recovery in solvent extraction-continuous precipitation asphalt pretreatment process

为提高工作效率,节省操作时间,需快速判断混合溶剂中洗油、煤油含量,用于指导沉降溶剂的回配。实验研究表明,洗油与煤油按不同比例混合,其密度也不同:洗油所占比例越大,密度越大,比例越小,密度越小,且在测试温度为20℃的条件下,混合质量比例与混合溶剂密度呈线性关系。

In order to improve the working efficiency and save the operating time, the content of washing oil and kerosene in the mixed solvent should be determined quickly, which can be used to guide the recovery of the settling solvent. Experimental research shows that wash oil and kerosene mixed in different proportion, the density is different: the greater the proportion of wash oil, the density, the greater the proportion is smaller, the smaller the density, and under the condition of test temperature is 20℃, mixing quality ratio has a linear relation with the density of mixed solvent.
