This paper presents a ultrasonic-capacitive system for online analysis of the quality of fuel
oils (FO), which are widely used to produce electric energy in Thermal Power Plants (TPP) …

During oil spills, an accurate estimate of the oil-slick thickness at different locations within
the affected area is an essential requirement to estimate the spilled amount, assess and …

In order to have on-line measurement of water content in heavy fuel oil (HFO), the so-called
water-cut meters are used. Typically, measurements performed by these devices are based …

The objective was to analyze a recently developed flow measurement technique based on
the vibration captured by an accelerometer attached to the pipeline surface for use in the oil …

This chapter describes the basic properties of ultrasonic technologies and their associated
use in various ranges of sensors in industrial applications. Physical properties as well as the …

According to current Brazilian regulations, if the volumes of oil produced used as a reference
for the payment of government shares and third parties contain a water content greater than …

This paper presents a laboratory feasibility study aiming at the development of a dual
modality sensor for development within an oil and gas extraction plant to measure the …

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 …

The use of impedance spectroscopy is described to diagnose the condition of oil in utility
transformers. Actual transformer oil samples having different dissolved fault gas and …

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 …
