Water-in-crude oil emulsions are formed during petroleum production and asphaltenes play an important role in their stabilization. Demulsifiers are added to destabilize such emulsions,however the demulsification mechanism is not completely known. In this paper, the performances of commercial poly(ethylene oxide-b-propylene oxide) demulsifiers were studied using synthetic water-in-oil emulsions ...

Turbine oil plays an important role in supporting optimal steam turbine performance. Some additives in turbine oil can cause emulsification when the oil is contaminated by water, so demulsibility is a very important property of the steam turbine oil. In order to improve the demulsibility of steam turbine oil, two kinds of polyether-silicone comb copolymers are synthesized and used as steam turb...

the oil refining industries are using a number of demulsifiers for dewatering and desalination of crude oil but experience has shown that universal demulsifiers can not be produced. each kind of water in oil (w/o) emulsion requires specific by composition demulsifier. in practice, synergetic effect of the interaction between different types of demulsifiers is often sought. for dewatering the w...

In this study, various water-soluble and oil-soluble demulsifiers were selected for separation of water from crude oil emulsions and their productivity measured using the Bottle-test method at 70 °C and 10 ppm concentration. The best ones among 23 demulsifiers examined through the screening process were fatty alcohol ethoxylate, triethanol amine and urea from the water-soluble group and Basoror...

Droplet microfluidics can form and process millions of picoliter droplets with speed and ease, allowing the execution of huge numbers of biological reactions for high-throughput studies. However, at the conclusion of most experiments, the emulsions must be broken to recover and analyze their contents. This is usually achieved with demulsifiers, like perfluorooctanol and chloroform, which can in...

Separation of water-in-oil emulsion is a significant part the cost oil production due to use expensive demulsifiers and additional heating by burning associated petroleum gas. The article discusses an acoustic method that enables increasing rate separation emulsion. In field conditions, tests were carried out in which efficiency was determined depending on temperature product, concentration dem...

Abstract The complicated nature of crude oil emulsions is part the major setbacks associated with postulation methods for phase separation and demulsification in industry. Despite increasing efforts generating efficient dependable methods, majority cannot be shattered reduced times. This review examines trending techniques petroleum Several approaches have been examined to discover best method ...

Short-term production optimization of oil assets concerns routing decisions and equipment control settings that induce optimal steady-state operations. Typically, the are made on scale hours to days with aim maximizing short-term economic gains. Still an evolving field, this paper contributes by presenting a model solution strategy for sequencing operations over time drive system towards state,...
