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 …

This review discusses recent research findings spanning the last two decades concerning
ultrasonic technologies applicable to the oil, gas, and coal sectors. Various experiments …

Crude oil is a mixture of hydrocarbons, dispersed water droplets, salt, and sediment in a
continuous oil phase. Presence of natural surfactants, and applied drag forces on the …

The main objective of this research is to determine the capability of four surface-active
compounds namely poly (ethylene glycol) distearate, N, N-dimethyldodecylamine N–oxide …

Water-in-oil emulsions pose significant challenges in the petroleum and chemical industrial
processes, necessitating the coalescence enhancement of dispersed water droplets in …

As most of the oil fields gradually come to the middle and late exploitation period, the crude
oil production becomes more complex, stable and water cut is also very high. This has …

The existence of saltwater in extracted crude oil causes major problems such as corrosion
and low quality of the extracted crude oil. Therefore, droplet coalescence of saltwater and …

The influence of feeding conditions on outlet drop sizes, dense-packed zone, and
separation efficiency of a liquid-liquid gravity separator was investigated experimentally. A …

Salts, organic materials, and hazardous materials can be found regularly in the effluent from
a desalter unit of crude oil. These materials should be separated from the wastewater. Four …

The removal of heavy metals from desalter effluent is an important issue due to the toxicity of
these pollutants. In this study, micellar‐enhanced ultrafiltration (MEUF) is applied for the …
