    炼油厂污油超声破乳脱水

    Ultrasonic demulsification and dewatering of refinery waste oil

    • 摘要: 以含水量(体积分数)20%~30%的中石化扬子炼油厂提供的污油为研究对象,在实验室条件下,采用超声波破乳技术进行脱水研究。在超声频率为20 kHz的条件下,考察了超声的其他参数对污油脱水的影响。结果表明:超声辐照时间为5min、超声激励电压为100V、超声辐照后热沉降温度为60℃、沉降时间为2h时,污油破乳脱水效果比较好,作用后,污油含水率可以降低到3.2%。按照小试得到的最佳工艺参数进行中试实验,其污油破乳脱水效果跟预计的结果相当,含水率可以降低到7.2%。
      Abstract: An ultrasonic demulsification technology has been studied in laboratory to intensify dewatering for the 20%-30% water-content waste oil from Sinopec Yangzi Petroleum & Chemical Co.The ultrasonic parameters are examined for waste oil dewatering with 20 kHz ultrasound.The results show that under the ultrasonic irradiation time of 5min,ultrasonic exciting voltage of 100V,settling temperature of 60℃ and settling time of 2h,the water content can be reduced to 3.2% in a small scale test.Middle-sized scale experimental results show that the water content as expected can be reduced to 7.2% with the parameters used in the small scale experiments.
