2024年1月1日 · This chapter provides information about different types of emulsion forms, such as O/W or W/O, and their stability mechanisms, and various emulsion breakers that can be used in demulsifying oil/water emulsions. Reverse emulsion breakers are comprehensively discussed in this current study.

2022年3月1日 · 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 possible to reverse the process, demulsifying the emulsion.

2015年7月1日 · Emulsions occur in almost all phases of oil production and processing: inside reservoirs, wellbores, and wellheads; at wet-crude handling facilities and gas/oil separation plants; and during transportation through pipelines, crude storage, and petroleum processing.

Two liquids can form different types of emulsions. As an example, oil and water can form, first, an oil-in-water emulsion, in which the oil is the dispersed phase, and water is the continuous phase. Second, they can form a water-in-oil emulsion, in which water is the dispersed phase and oil is the continuous phase.

This guide explores the science behind Water-in-Oil (W/O) emulsions, their distinctions from Oil-in-Water (O/W) systems, and the role of emulsification processes in creating stable, functional emulsions.

Water–oil emulsions for abrasive machining can be classified into three subgroups, namely, oil-concentrate, semisynthetic, and synthetic emulsions. Oil-concentrate emulsions are called soluble oils. Soluble oils are typically general-purpose products …

2022年4月11日 · Herein, the sources, classification, formation, stabilization, and separation of oil–water emulsions are systematically summarized. The roles of different interfacially active...

2006年1月1日 · Emulsification is a process whereby water-in-oil emulsions are formed. These emulsions are often called "chocolate mousse" or "mousse" by oil spill workers. When emulsion form, the...

2022年4月11日 · Herein, the sources, classification, formation, stabilization, and separation of oil–water emulsions are systematically summarized. The roles of different interfacially active materials–especially the fine particles–in stabilizing the emulsions have been discussed.

2024年11月7日 · We present a Janus channel of membranes (JCM) that features a confined architecture constructed of a pair of hydrophilic and hydrophobic membranes, which allows for concurrent, highly efficient recovery of oil and water from surfactant-stabilized emulsions.
