“…This can be explained by the boiling effect due to generated heat and cavitation phenomenon, which assist the evaporation of light components [9,12]. The boiling effect was started at 10 min and obviously observed at 15 min.…”

“…Generally, this figure demonstrates that with increase in solvent concentration the fuel oil viscosity decreases. This can be because of increase in solubility of some hydrocarbons (saturates, asphaltenes, resins, aromatics) by increase in solvent concentrations [12]. In this stage, acetonitrile concentration of 5 vol % was determined as the most effective concentration in decreasing of viscosity.…”

“…Cavitation phenomenon increases the mass and heat transfer and is effective on flow rheology [9][10][11]. Shedid [12] introduced an ultrasonic irradiation technique for treatment of asphaltene deposition. The author investigated the influences of using ultrasonic irradiation on asphaltene behavior in the UAE crude oil, with consideration of solvent and temperature effects.…”

“…Decrease in fuel oil viscosity before 5 min may be interpreted by production of ultrasonic energy, which may make degradation of hydrocarbons intermolecular bonds and their separation from other particles. On the other hand, increase of fuel oil viscosity after 5 min can be attributed to a breakdown of large molecular of hydrocarbons such as asphaltene to more tiny cracked particles in the fuel oil samples[9,12,30,31].…”

“…Some literatures have already been reported on formation and wellbore stimulation by ultrasonic technologies. Some authors carried out experiments on the removal of asphaltene depositions, paraffin precipitation and wax about formation damage remediation with ultrasonic technology (Gollapudi et al, 1994;Zekri et al, 2007;Shedid, 2004;Brian et al, 2007). Recently, the laboratory study concerning the application of ultrasound to enhance well stimulation were discussed by some researchers (Bjorndalen and Islam, 2004;Amro et al, 2007;Tunio et al, 2011).…”

Ultrasonic treatment as an economical and green technology has been much attended in petroleum industry, especially for inhibition and removal of asphaltene deposition in the near wellbore region. The performance of ultrasonic waves is affected by different parameters such as time, power, frequency, type of radiation, etc. In this communication, the effects of duration of ultrasonic radiation, power, and stability on asphaltene aggregation were evaluated from a kinetic point of view. In fact, the optimal radiation conditions were determined by comparing the growth kinetics and size distribution of asphaltene particles. The optimal exposure time and power of ultrasonic radiation for the oil sample were obtained at 150 s and 40 W, respectively. In addition, the negative effect of time duration on the aggregated asphaltene particle diameter was observed. The effect of ultrasonic radiation on prevention and removal of asphaltene deposits was examined by observation of changes in asphaltene particle diameter. The results demonstrated the beneficial effect of ultrasonic waves on inhibition of asphaltene deposition. In order to investigate the effect of ultrasound on asphaltene deposition in porous media, the oil sample was radiated with ultrasound at the most optimal conditions, which were obtained in the previous experiments. Moreover, the trend of asphaltene particle deposition in porous media (micromodel) at optimal conditions was compared to the same oil sample without ultrasonic radiation. Comparison of pressure drop curves showed that the use of ultrasound in determined optimum conditions reduces the amount of asphaltene deposition.
