以酮苯脱蜡装置所用的大庆减二线馏分油为原料 ,进行了加入脱蜡助滤剂的试验研究工作。结果表明 ,采用的 5种助滤剂对抚顺石油化工公司石油二厂酮苯脱蜡车间的原料油都有好的助滤效果。助滤剂不同 ,其加入量不同 ,助滤效果也不同。其中D1助滤剂在加入量为 5 0 0 μg/g时 ,可提高过滤速度 98% ,脱蜡油收率增加 5 .1个百分点。复合助滤剂的效果好于单助滤剂 ,其中采用 2 0 0 μg/g的D5和 30 0 μg/g的D4的复合助滤剂效果最好 ,脱蜡油收率提高 7个百分点 ,过滤速度提高 5 0 %。所选择的 5种国产助滤剂对抚顺石油化工公司酮苯脱蜡装置的蜡及脱蜡油无任何不良影响。
The experimental study of adding dewaxing filter aid was carried out in Daqing Reduced Second Distillate Used in Ketone Dewaxing Unit. The results showed that the five filter aids used had a good drainage effect on the feedstock oil of the Ketone-Benzene Dewaxing Workshop in Fushun Petrochemical Company. Different filter aid, its different amount of added, filter aid effect is also different. D1 filter aid in the amount of 500 g / g, can increase the filtration rate of 98%, dewaxed oil yield increased by 5.1 percentage points. The effect of compound filter aid is better than that of single filter aid. The compound filter aid with D0 of 200 μg / g and D4 of 30 0 μg / g is the best, the yield of dewaxed oil increased by 7% Filtration rate increased by 50%. The five kinds of domestic filter aid selected have no adverse effect on the wax and dewaxed oil of the Fushun Petrochemical Company Kethenbide Dewaxing Unit.
