What Is Demulsifier Injection?

Demulsifiers are compounds that dispersed in very small amounts into the emulsion during injection that diffuse into the oil-water interface and function as stabilizers.

What is the purpose of using a demulsifier?

Demulsifier is a chemical used to break emulsions that is, to separate the two phases. The type of demulsifier selected depends on the type of emulsion, either oil-in-water or water-in-oil. Demulsification is used for the separation of water from crude oil.

How does a demulsifier work?

These chemicals are designed to neutralize the stabilizing effect of emulsifying agents. Demulsifiers are surface-active compounds that, when added to the emulsion, migrate to the oil/water interface, rupture or weaken the rigid film, and enhance water droplet coalescence.
