Discharges of oily water are common among a number of commercial operations. If
unregulated these effluents can lead to both short and long term adverse environmental …

In the oil industry, many applications require the measurement of more than one liquid level
interface, often in challenging, environments. In this paper, an ultrasonic technique has been …

In this paper an oil–water de-emulsification process within large tanks using ultrasonic
technology is presented. As the device would operate in hazardous areas, it should not …

Separating produced water is a key part of production processing for most crude oils. It is
required for quality reasons, and to avoid unnecessary transportation costs and prevent …

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 …

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 …

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 …

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

This paper aims to separate a water-in-oil emulsion using ultrasonic standing waves
generated by a piezoelectric transducer inside a channel under the transient flow regimes …

As operators seek to re-inject produced waters back into reservoirs for disposal it is critical to
be able to measure the concentration of oil remaining within the produced water. Excessive …
