Cleaning agents
When using chemical cleaning agents, make
sure you follow the general rules and suppliers’
recommendations regarding ventilation,
protection of personnel, etc.
For separator bowl, inlet and outlet
A chemical cleaning agent must dissolve the
deposits quickly without attacking the material
of the separator parts.

For cleaning of lube oil separators the most
important function of the cleaning agent is to be
a good solvent for the gypsum in the sludge. It
should also act as a dispersant and emulsifier
for oil. It is recommended to use Alfa Laval
cleaning liquid for lube oil separators which has
the above mentioned qualities. Note that carbon
steel parts can be damaged by the cleaning
agent if submerged for a long time.
•
Fuel oil sludge mainly consists of complex
organic substances such as asphaltenes. The
most important property of a cleaning liquid for
the removal of fuel oil sludge is the ability to
dissolve these asphaltenes.
