5.7.1 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.
Alfa Laval cleaning liquid for fuel oil
separators
has been developed for this
purpose. The liquid is water soluble, non-
flammable and does not cause corrosion of
brass and steel. It is also gentle to rubber and
nylon gaskets in the separator bowl.
Before use, dilute the liquid with water to a
concentration of 3-5%. Recommended
cleaning temperature is 50-70 °C.
CAUTION
Skin irritation hazard
Read the instructions on the label of the
plastic container before using the cleaning
liquid.
Always wear safety goggles, gloves and
protective clothing as the liquid is alkaline
and dangerous to skin and eyes.
