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. This water (and salt) must be removed from the crude oil prior to refining.

The meaning of DEMULSIFY is to convert into a form that resists emulsification : break.

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: A fast rate of separation, a low value of residual water in the crude oil, and a low value of oil in the disposal water are obviously desirable.

2024年9月4日 · What is A Demulsifier? A demulsifier, also known as an emulsion breaker, is a chemical additive used to separate or “break” emulsions (water-in-oil or oil-in-water emulsions) into distinct oil and water phases.

BASF offers a wide variety of demulsifiers from different chemical classes to help our customers make tailor-made, high-performance formulations. Demulsifiers from the Basorol ® portfolio are especially designed for fast water dropping, drying and desalting.

2024年5月21日 · A demulsifier is a substance that can cause emulsified substances to separate. For this reason, such chemicals are often referred to as emulsion breakers. There are many …

2024年2月15日 · Demulsifiers are substances with a very high surface activity that can lower the interfacial tension between water and oil by advancing interactions at liquid-liquid interfaces (Acosta et al., 2020). Demulsification techniques are mainly categories into three classes, i.e., physical, biological, and chemical.

To recover as much oil as possible from these reserves, crude oil demulsification is used for better oil separation. Breaking these emulsions helps to meet production targets, adhere to …

2016年10月1日 · Demulsification is an intricate process as oilfield emulsions are, in principal, complex, stable liquid-liquid colloidal suspensions comprising of dispersed/internal phase, continuous/external phase, and emulsifying agents basically present at the oil-water interface.

2015年7月6日 · Demulsifier selection should be made with the emulsion-treatment system in mind. Some of the questions to be asked include the following. What is the retention time of the emulsion in the equipment? What type of emulsion is to be treated? What is the water cut? Is the system heated, or can it be heated if necessary?
