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.
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.
