Demulsifier - Wikipedia
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.
Demulsifiers - BASF
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.
Demulsifiers: what they are and why they are needed
2022年10月19日 · A demulsifier is a substance to separate an emulsion into its components. It consists of two liquids which neither mix with each other nor separate into phases - small droplets of one liquid are evenly distributed in the volume of the other liquid.
Oil demulsification - PetroWiki
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.
Our KemelixTM range of demulsifiers facilitate the economical removal of water from crude, by utiling a wide range of chemistries including resin alkoxylates, polyimine derivatives and modified polyols.
Chemical Demulsifiers - SLB
Demulsifier chemicals formulated to complement the crude oil dehydration process and enable efficient desalting of crude oil. Demulsifiers ensure that the residual water and salt content in crude and the oil content of separated water meet required specifications.
Demulsifiers Explained: Breaking Down Emulsions in Oil and Water …
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.
What is a Demulsifier? (with pictures) - AllTheScience
2024年5月21日 · A demulsifier is a substance that causes emulsified substances to separate. Also called an emulsion breaker, a demulsifier can be...
Demulsifiers: What Are They and Why Your Operation Needs Them
2014年10月10日 · By adding a chemical demulsifier – chiefly comprising polymers – the water and oil are brought together into separate bodies quickly, making it easy to extract the one from the other. As you would expect, there are various chemical demulsifiers (also known as Emulsion Breakers) on the market.
Application of Ionic Liquids for Chemical Demulsification: A Review
Chemical demulsification is implemented by adding a desired amount of demulsifier to emulsions and mixing them vigorously. After mixing, sufficient time is required to allow Ostwald ripening, flocculation, coalescence, and phase separation (creaming/sedimentation) to occur.
