Detection of liquid-liquid interface is critical in solvent extraction equipment/contactors
typically used in petroleum and hydrometallurgical industries. An instrumentation system …

Ultrasonic based techniques have been explored to monitor emulsion layer and separation
of oil and water phases from their emulsions. Creation of oil and water emulsions is a …

Controlled flow rate tests using mixtures of crude oil and water at different mass fractions
were carried out in a flow loop at the University of Tulsa. A noninvasive acoustic method …

The extraction process of crude oil requires addition of water, resulting in complex
emulsions, in which the phases must be separated before the petrochemical processing …

A technique for noninvasive ultrasonic characterization of multiphase crude oil-water-gas
flow is discussed. The proposed method relies on determining the sound speed in the …

Selecting and designing the optimum ultrasonic probe is vital for ultrasonic measurements
and experiments. The amplitude of the emitted ultrasonic wave excitation signal as well as …

A combination of ultrasonic transducers operated in continuous mode and a conductance/
