摘要
通过试验得到:在去离子水中掺入AES后,其表面张力系数显著降低了,AES的浓度越大,其表面张力越小。该溶液经超声波处理后:表面张力系数有一定的上升,超声波功率越大、作用时间越长,表面张力系数上升越大;随超声波作用时间的增加,该溶液的化学需氧量越来越小,但随作用时间的增加,下降的趋势变慢。掺入AES后,原油的粘度有了较大的降低,其降粘率超过了80%。超声波对掺入AES的原油作用后,原油的降粘率超过了92%。
The coefficient of surface tension reduced significantly when AES was introduced into the deionized water. The concentration of AES is higher, the coefficient of surface tension is smaller.The coefficient of surface tension of the deionized water increased with the power and the action time of ultrasound.The volue of chemical oxygen demand is more small with the increase of the action time of ultrasound,but the trend downward slowed down. The viscosity had been greatly reduced and the viscosity reduction rate was more than 80% when AES was introduced into the crude petroleum. The viscosity reduction rate was more than 92% when the crude petroleumof introduced AES was treated by ultrasound.
