experimental study on Viscosity reduction for residual oil by ultrasonic
Ultrasonics Sonochemistry, 2018Co-Authors: Xintong Huang, Cuihong Zhou, Lanting Zhang, Shihan WangAbstract:Abstract Because of characteristics of large density, high Viscosity and poor mobility, the processing and transportation of residual oil are difficult and challenging, Viscosity reduction of residual oil is of great significance. In this paper, the effects of different placement forms of ultrasonic transducers on the sound pressure distribution of ultrasonic inside a cubic container have been simulated, the characteristics of oil bath heating and ultrasonic Viscosity reduction were compared, Viscosity reduction rule of residual oil was experimentally analyzed by utilizing Response Surface Method under conditions of changing ultrasonic exposure time, power and action mode, the mechanism of Viscosity reduction was studied by applying Fourier transform infrared spectrometer, the Viscosity retentivity experiment was carried out at last. Experiments were conducted using two kinds of residual oil, and results show that ultrasonic effect on the Viscosity reduction of residual oil is significant, the higher Viscosity of residual oil, the better effect of ultrasonic, ultrasonic power and exposure time are the significant factors affecting the Viscosity reduction rate of residual oil. The maximum Viscosity reduction rate is obtained under condition of ultrasonic power is 900 W, exposure time is 14 min and action mode of exposure time is 2 s and interrupting time is 2 s, Viscosity reduction rate reaching up to 63.95%. The infrared spectroscopy results show that light component in residual oil increased. The Viscosity retentivity experiment results show that the Viscosity reduction effect remains very well. This paper can provide data reference for the application of ultrasonic in the field of Viscosity reduction for residual oil.

understanding the importance of the Viscosity contrast between the sample solvent plug and the mobile phase and its potential consequence in two dimensional high performance liquid chromatography
Journal of Chromatography A, 2009Co-Authors: Ross A Shalliker, Georges GuiochonAbstract:Abstract The effect of solvent Viscosity mismatch on elution performance in reversed-phase HPLC was studied using moment analysis. Two conditions were tested: (1) the mobile phase Viscosity was less than the injection plug Viscosity, and (2) the mobile phase Viscosity was greater than the injection plug Viscosity. Under the first condition, retention time and elution performance decreased as the Viscosity contrast between the mobile phase and injection plug increased. The effect on performance was more marked as the injection volume increased. A decrease in performance of 12% for compounds with retention factors up to 2.8 was apparent even when the Viscosity contrast was only 0.165 cP. In the second set of conditions, elution performance was actually observed to increase, by as much as 25% for a 40 μL injection, as the Viscosity contrast between the mobile phase and the solute plug increased. No change in the retention factor was observed. This behaviour was attributed to the shape of an injection plug as it enters into the column, whereby a low Viscosity plug permeates away from the wall when the column contains a higher Viscosity mobile phase, and vice a versa for a high Viscosity plug entering a low Viscosity mobile phase. At no stage was either a band splitting or shoulders observed with Viscosity contrasts up to 1.283 cP, as could have been expected.
