内蒙古油砂油脱泥、脱砂工艺研究

摘要

以内蒙古扎赉特旗油砂水洗分离生成油为研究对象,采用有机溶剂萃取和水洗后处理相结合的方法,对油砂油进行脱泥、脱砂工艺研究.考察了有机溶剂种类、剂油质量比、温度、时间、水洗试剂质量分数等条件对油砂油脱泥、脱砂工艺研究的影响.结果表明,在剂油质量比为1∶1,水洗温度90℃,水洗试剂质量分数8％,分离时间为25 min的条件下,采用1号溶剂油处理后的油砂油萃取率可达到94％以上.%With oil sand oil washing separation from oil sand of Inner Mongolia Zalaiteqi as the research object,using method of combining organic solvent extraction and water washing to research desliming sand-out technology of oil sand oil from Inner Mongolia.The influences of the organic solvent types,agent oil ratio,temperature,time,water reagent concentration and other conditions on the process of the oil sand oil desliming sand-out technology were investigated.The results show that using 1 # solvent oil processing oil sand oil can make the 94 ％ yield,under the condition of the organic solvent and oil sand oil quality ratio of 1 ∶ 1,water temperature 90 ℃,water reagent concentration 8％,separating time 25 min.
