摘　　要：以含机械杂质较高的印尼油砂油为实验对象,采用超声沉降法进行了强化脱除油砂油中机械杂质的实验研究。通过单因素实验考察超声波分离时间、焦化柴油质量分数、沉降时间、沉降温度对油砂油机械杂质脱除率的影响,通过正交实验确定印尼油砂油破乳除杂的适宜条件。结果表明,与传统沉降法相比,采用超声沉降法油砂油机械杂质的脱除率提高10%以上。在实验条件范围内,随着焦化柴油质量分数、超声沉降时间、沉降温度的增加,油砂油中机械杂质质量分数逐渐减小,机械杂质的脱除率逐渐增大,其中焦化柴油质量分数对精制油机械杂质质量分数影响最为显著。采用超声沉降法脱除印尼油砂油机械杂质的适宜条件为:沉降温度80℃,超声沉降时间4.4h,超声波分离时间10.4 min,焦化柴油质量分数为30.9%。在此条件下,油砂油中最小机械杂质质量分数为0.26%。The subject of experiment is oil-sands-oil with high mechanical impurity.The study on the enhanced removal of mechanical impurities in oil-sands-oil was carried out by ultrasonic-sedimentation method.The effect factors including ultrasonic separation time,proportion of coking diesel oil,sedimentation time and sedimentation temperature were studied,respectively.The suitable conditions of demulsification and deimpurity in Indonesia's oil-sands-oil were investigated by orthogonal experiment.The experimental results show that compared with the traditional sedimentation method,the removal rate of mechanical impurities in oil-sands-oil is increased by more than 10% by ultrasonic-sedimentation method.With the increase of the proportion of coking diesel oil,sedimentation time and sedimentation temperature,the proportion of mechanical impurities in oil sands decreased and the removal rate of mechanical impurities gradually increased.The proportion of coking diesel oil was the most important factor on the mechanical impurity proportion of refined oil.The optimum conditions for the removal of mechanical impurities by ultrasonic-sedimentation method are as follows:the sedimentation temperature of 80℃,sedimentation time of 4.4 h,ultrasonic cleaning time 10.4 min and the mass proportion of coker diesel oil of 30.9%.Under the optimal conditions,the minimum mechanical impurity in the oil-sands-oil was 0.26%.
