摘要： 以内蒙古油砂为考察对象,采用水洗方法进行油砂分离及尾砂环保处理。分离油砂实验中考察了分
离温度、试剂碱质量分数、分离时间、剂砂质量比对油砂油收率的影响,尾砂环保处理实验中考察了试剂碱的质量分
数对尾砂含油率的影响。实验结果表明,在分离温度80℃、试剂碱质量分数8%、分离时间25min、剂砂质量比
2.0:1时,内蒙古油砂的分离效果最好;用低质量分数的试剂碱多次水洗内蒙古尾砂,可以使尾砂含油率降低到
0.3%,pH 值降低到9,达到尾砂排放标准。

Abstract: The Separation of oil from the Inner Mongolian oil sand with washing method and its tails treatment for environment protection have been studied. The factors including washing temperature, the reagent weight fraction, the disengaging time and agents sand ratio on oil separation were checked, while in the tails treatment experiment, effect of the weight fraction of reagent on tailings oil content has been studied as well. The experimental results show that best oil separation performance could be obtained under the following conditions: washing temperature 80 ℃, the reagent mass fraction of 8%, separation time of 20 min, sand agent mass ratio of 2∶1. Inner Mongolia tailings treatment by washing multiply with low concentration of reagent, and the mass fraction of the oil content of the tailings can be reduced to 0.3%, which can meet with the requirement of emission standards of the tailings.
