【摘要】 以鲁宁管输原油为研究对象,进行了动态超声波原油破乳的小试实验。考察了超声波作用对油中水粒子的凝聚作用,经过显微跟踪分析,油中水粒子的粒径明显变大,有利于原油的脱水;比较了超声波电脱盐联合脱盐和单一电脱盐的效果。在超声电脱盐联合作用下,原油盐含量由39.4 6 3mg/L降至3.16 2mg/L左右,而单一电脱盐在相同条件下,原油盐含量只能降到7.0 4 8mg/L左右;实验研究了操作温度和超声发生器输出电压对脱盐效果的影响。提高操作温度有利于原油的破乳。超声波发生器输出电压存在一个最优值5 0V ,在该实验条件下使脱后盐含量降至最低。更多还原

【Abstract】 The technology for ultrasound enhancement of desalting of the crude oil is critically described After the radiation of ultrasound, it can be observed with microscope that the size of water drop grows obviously It proves ultrasound has the agglomerate effect on the water particle in the oil This paper also studies the desalting effect of ultrasound combined with electrical treatment, by means of which the salt content of the oil can be reduced from 39 463mg/l to 3 125mg/l under the optimum experimental conditions The enhancement of operating temperature is beneficial to demulsification process There is an optimum value for output voltage of ultrasonic generator更多还原
