Emulsion breaking

emulsions, emulsifying agent Emulsions are liquids distributed homogeneously in a mixture.

Oil-in-water emulsions, so-called cooling lubricants, are the emulsions

most frequently used in industrial applications. To make these cooling

lubricants (emulsions), an oil is emulsified homogeneously in an

aqueous phase (approx. 5% oil) using emulsifying agents. Emulsions

become contaminated after a certain amount of time and must be disposed


The procedure of re-separating the oil and water phases is called emulsion breaking.

Emulsion splitting, oil phase, acid splitting

In conventional acid cleavage, the emulsion is heated to about 90°C and

a strong acid is added to it. Under these conditions, the oil separates

from the water phase and floats to the surface. This process requires a

large amount of energy and can no longer be considered

state-of-the-art, not least due to the high level of salinization of

the water phase.

The use of organic emulsion breakers is much more economical. Using our

mixture breakers POLY SEPAR® CFL, whose metal component removes

surfactants etc., clear water is achieved.
