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 …

This work deals with a transmission-reception ultrasonic technique for the real-time
estimation of the water content in water-in-crude oil emulsions. The working principle is the …

A low-cost sensor integrating chipped ultrahigh-frequency radio frequency identification
(UHF RFID) and paper flow channels is designed to characterize water content (WC) in oil …

This study introduces an innovative approach to the layered model, emphasizing the
physical–chemical characterization of miscible liquid systems through ultrasonic techniques …

The presented research addresses the problem of dependency analysis of the ultrasonic
signal measured by a sensor in an engine oil bath. The dependency analysis is performed …

This work proposes the slope of the phase spectrum as a signal processing parameter for
the ultrasonic monitoring of the water content of water-in-crude oil emulsions. Experimental …

The separation of oil emulsions is an important step in the purification of crude oil from
water, mineral salts, and various associated contaminants, asphaltene-resinous substances …

This work deals with the development of an ultrasonic backscattering sensor for the
monitoring of water-in-oil emulsion. The sensor consists of a 3.5-MHz ultrasonic transducer …
