超声波技术在蜡油脱金属中的应用

使用脱金属剂在超声波作用下脱除油品中金属。重点探讨了反应时间、超声波参数、脱金属剂的质量分数对金属脱除率的影响。实验结果表明,使用超声波脱金属的效果明显优于未加超声波的脱金属效果,可以在10 min内达到较高的金属脱除率。当脱金属剂的质量分数为1 500μg/g,在超声波作用下反应10 min,超声波强度为8 W/cm2时脱金属效果较好,镍和钙的脱除率均可达到80%以上,锌的脱除率达90%以上。

Application of Ultrasound in Removing Metals From Wax-Bearing Crude

Metal elimination agent was used to eliminate the metal from the oil under the ultrasound radiation.The influences of the reaction time,ultrasound parameter and metal elimination agent mass fraction on the metal removal rate were discussed.The results show that the metal elimination effect with ultrasound is much better than without it.It can reach very high metal elimination rate in 10 min.The metal elimination effect is the best when the metal elimination agent mass fraction is 1 500 μg/g,the ultrasound radiation time is 10 min and the ultrasound intensity is 8 W/cm~2.The removal rate of Ni and Ca all is above 80%,and Zn removal rate is above 90%.
