“…Acoustic cavitation involves the utilization of high-frequency sound waves, typically ultrasound with frequencies ranging from 16 kHz to 100 MHz. The alternating cycles of compression and rarefaction in the sound waves lead to different stages of cavitation, including the formation of the bubble cavity, a growth phase, and ultimately a collapse phase that releases a significant amount of energy locally. − An alternative method is for inducing cavitation through hydraulic devices. This phenomenon takes place as fluid passes through a narrowing, such as a valve, orifice plate, or venturi, leading to cavitation caused by the linear flow .…”

Petroleum refineries are one of the largest greenhouse gas (GHG)emitting industrial sectors. One of the ways by which refineries can reduce emissions is by reducing the consumption of utilities (heat and steam) required in the refineries or by increasing the throughput of the refinery. Process intensification is one way by which throughput can be increased, and also process heat requirements can be reduced. Cavitation-driven process intensification has created many opportunities in the field of nanoparticle synthesis, wastewater treatment, water disinfection, crystallization, depolymerization, extraction, and emulsification. In recent years, cavitation-assisted bitumen processing has been explored in petroleum refineries. The present Review focuses on the studies related to cavitationally driven transformations in bitumen processing. Case studies have been critically reviewed in various aspects related to the use of cavitation in bitumen recovery from sands, bitumen viscosity reduction, bitumen desulfurization, improving compatibility of rubberized bitumen, bitumen nanoemulsion, and bitumen wastewater treatment. The present Review would be a ready reckoner highlighting the relative advantages and the current status of cavitation-assisted applications of bitumen. This Review also highlights the research gap and proposes future work in the area of cavitation technology for bitumen processing.

To study the behavior of a bubble clusters in cavitation devices, a numerical study of the dynamics of bubbles in a compressible liquid was performed, taking into account interfacial heat and mass transfer. The influence of regime and system parameters on the intensity of cavitation processes is considered. Physical and chemical transformations during the cavitation treatment of liquids are caused not only by the action of shock waves and emitted pressure pulses but also by extreme thermal effects. At the stage of extreme compression of the bubble, the vapor inside the bubble and the liquid in its vicinity transform into the state of a supercritical fluid. The presented model analyzes the nature of microflows in the interbubble space and carries out a quantitative calculation of the local values of the parameters of the velocity and pressure fields.
