Effect of Ultrasonic Treatment on the Properties of High-Paraffin Low-Resin Oil, Sediments, and Raffinates

The effect of ultrasonic treatment on the properties of highly paraffinic oil, its sediments, and raffinates was studied. The oil was processed in an ultrasonic field (field intensity, 18 W/cm 2 ; frequency, 22 kHz; and time, 10 min), and sedimentation was carried out at an ambient temperature of 30...

Summary:The effect of ultrasonic treatment on the properties of highly paraffinic oil, its sediments, and raffinates was studied. The oil was processed in an ultrasonic field (field intensity, 18 W/cm 2 ; frequency, 22 kHz; and time, 10 min), and sedimentation was carried out at an ambient temperature of 30°C; the coldfinger temperature was 5°C. The viscosity–temperature parameters of oil were determined using a HAAKE Viscotester iQ rotational viscometer. The microstructure of the sediments was studied using an AXIOLAB.A1 microscope. The concentrations of weak and strong acids in oil, raffinates, and sediments isolated from highly paraffinic oil were determined using a potentiometric titration method.
