| Abstract: | The basic principle of crulde-oil dehydration by ultrasonic demulsiflcation is elucidated. Effects of the ultrasonic-field parameters on the crude-oil dehydration rate are experimentally studied as well. It was focused from the experiments that the acoustic intensity,time of irradiation and frequency are the primay factors which affect the dehydrated rate, while the ratio of intermittent and pulse duration are the secondary factors. In this experimental system, the optimum acoustic immensity, frequency, ratio of intermittence, pulse duration and time of irradiation are 0.65W/cm', 20kHz, 8, 9.7ms and 5-10min, respectively. |
