During the development of natural gas reservoirs, predicting the bubble size distribution and transport velocity in the study of gas-water two-phase flow through porous media is extremely important in natural gas recovery. Considering the different…
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 desalination have been paid much attention by researchers about…
Water (W) and oil (O) normally mix during production and while passing through valves and pumps to form a persistent water-in-oil (W/O) emulsion, which is a serious restriction in oil production and transporting and refining processes. The objective…
The flow modes of a vapor-drop mixture in a regasifier-heater of liquefied natural gas are numerically studied on the basis of the model that takes into account polydispersity, power, and thermal interaction of phases, processes of breakup,…
Crude oil dehydration is one of the first, most important and challenging steps in oil production and processing. To achieve rapid and energy-optimized demulsification of water-in-oil emulsions, Saudi Aramco and TechnipFMC have jointly developed a…
Clarifying agent is an important agent to treat the wastewater produced from the polymer flooding in oil field (it containing residual polymers) and different type of clarifying agent realizes different oil-water separation processes. Three kinds of…
The efficient separation of water-in-oil emulsions plays significant roles in the petroleum and chemical industries, but deep purification using a single method is difficult. In this work, a combined treatment integrating a direct current electric…
Green oil-field chemicals based on ionic liquids (ILs) are highly recommended as demulsifiers for heavy crude oil emulsions due to their low vapor pressure, high thermal and chemical stability against degradation in harsh processing conditions. Novel…
We describe herein the design of a small AC electrostatic model coalescer for investigating coalescence efficiency of water in oil emulsions. The function of the model coalescer is tested on emulsions with different water cuts. In the coalescer,…
In the petroleum industry, oil and water emulsions are frequent, not only in oilfield operations but also during the transportation and refining processes. Once depicting emulsion formation and stabilization, it is essential to analyse how it is…

The separation of water droplets from water-in-crude-oil emulsions is a vital process in the petroleum industry. Various components in crude oil, such as asphaltene, stabilize the water–oil interface, which inhibits the coalescence of water droplets.…
The crude oil recovery process is frequently associated with the formation of stable emulsions due to factors such as turbulent flow in pipelines and the presence of surface-active substances that naturally occur in crude oil. These emulsions are…
Industrial wastewater containing oil fraction is the main type of pollution of most railway transport enterprises during external and internal washing of rolling stock, water pressure testing of its components, and parts. Wastewater is also a problem…
The gas–liquid flow behavior laden by hydrate particles is significant for the flow assurance of submarine natural gas hydrate production. An integrated multiphase flow model considering the coalescence and breakage of bubbles and hydrate particles…
Profile control is utilized to redirect the injection water to low permeability region where a large amount of crude oil lies. Performed gel particles are the commonly used agent for redistributing water by blocking the pores in high permeability…
