Demulsifier - Wikipedia
网页Demulsifiers, or emulsion breakers, are a class of specialty chemicals used to separate emulsions, for example, water in oil. They are commonly used in the processing of crude oil, which is typically produced along with significant quantities of saline water.
Demulsifiers - BASF
网页Demulsifiers are key components of production formulations which enable the quick separation of produced water from oil. Separating oil from water can be very time critical due to short residence time. BASF offers a wide variety of demulsifiers from different chemical classes to help our customers make tailor-made, high-performance formulations.
Oil demulsification - PetroWiki
网页2015年7月6日 · Demulsification is the breaking of a crude oil emulsion into oil and water phases. From a process point of view, the oil producer is interested in three aspects of demulsification: Rate or the speed at which this separation takes place. Amount of water left in the crude oil after separation. Quality of separated water for disposal.

Chemical Demulsifiers - SLB
网页Demulsifiers ensure that the residual water and salt content in crude and the oil content of separated water meet required specifications. They disrupt the ordered structure of the natural surfactants that stabilize the emulsion, enabling the dispersed droplets to coalesce and form larger droplets that move to the oil/water interface.
Demulsifier: An Important Agent in Breaking Crude Oil Emulsions
网页2022年3月1日 · Effectively breaking an emulsion is very important in the petroleum industry since the produced crude oil is accompanied by water, which is linked to emulsions and can cause various environmental issues. To resolve these issues, surfactants are combined with crude oil to achieve a stable emulsion.
Review on demulsification techniques for oil/water emulsion: …
网页2024年2月15日 · Chemical demulsifier is the earliest and most common technique used for oil and water separation (Nikolov et al., 1996; Krawczyk et al., 1991; Hjartnes et al., 2019) due to its low cost and easy approach. Typical chemical demulsifiers contain surfactants, aromatic compounds, and flocculants.
A critical review of development and demulsification mechanisms of ...
网页2020年1月14日 · In agreement with the physicochemical formulation concept, demulsifier is a hydrophilic surfactant which can obtain optimum formulation at the water and oil interface. As reported in this study, the demulsifier involves the mixture of lipophilic and hydrophilic surfactants which are capable of performing demulsification.
Demulsifiers - ScienceDirect
网页2015年1月1日 · The object of using an emulsion breaker, or demulsifier, is to break the emulsion at the lowest possible concentration and, with little or no additional consumption of heat, to bring about a complete separation of the water and reduce the salt content to a minimum.
Surfactants as Integral Components of Chemical Demulsifiers
网页2021年6月20日 · Irrespective of the emulsion type formed, demulsification is a costly exercise in the oil and gas industry.
