<p>The proposed process involves subjecting the liquid, raw material to ultrasound treatment in a closed-circulation system, the intensity of the ultrasound being set at 1-10 MW/m2. Between 0.1 and 80 vol % of a dispersing agent is introduced into the treatment area at the same time as the raw material; it sustains static pressure of between 0.2 and 5 MPa. The device used in carrying out this process contains an ultrasonic activator which generates ultrasound at an intensity of 1-10 MW/m2 and is connected to an appliance (19) for separating the liquid and vapour phases of the processed crude, and a device (27) for condensing the end product.</p> |
