Research on the static experiment of super heavy crude oil demulsification and dehydration using ultrasonic wave and audible sound wave at high temperatures.

In this paper, the static experiment of super heavy crude oil demulsification and dehydration using ultrasonic irradiation at high temperatures is carried out. How the all factors, such as ultrasonic frequency, sound intensity, ultrasonic power, ultrasonic treatment time, sedimentation time, temperature and water ratio, affect ultrasonic crude oil demulsification and dehydration are summarized though this experiment. In addition, recent progress on ultrasonic demulsification equipment in China are reviewed. The purpose of this paper is to provide equipment and technical support for the extensive application of the technique of ultrasonic demulsification and dehydration.
