ASPHALTENE DISPERSANTS AND FUEL STABILIZERS HAVE MANY
BENEFICIAL EFFECTS:
Disperse existing sediment and sludge, and prevent new
formation of sludge.
Allow the blending of different fuels and fuel components
without asphaltene flocculation.
Optimise the selection of fuel blend components for
improved fuel quality and cost effectiveness.
Reduce tank corrosion by dispersion of water into the oil.
Reduce the need for tank cleaning and costly sludge disposal.
Disperse asphaltene agglomerations.
Improve the storage stability of the oil.
Prevent
fouling of the oil preheater

ASPHALTENE
DISPERSANT AND FUEL STABILIZER
Sludge formation and
deposits in fuel tanks and oil lines
Sediment and sludge are formed in oil tanks and fuel lines due to water
separation from the fuel oil and when asphaltenes, waxes and other
materials flocculate (stick together) and
ultimately settle to the bottom.
A certain amount of water is always found in fuel oil and additional
water can come from condensation in
the storage tank and during tank filling. The water normally separates out
and remains at the bottom of the fuel tank in direct contact with the
metal surface. Under the right conditions, micro-organisms
can grow at the water/oil interface and contribute to an increase in the amount of
sediment in the tank. The by-products of the micro- biological degradation causes
corrosion of metal surfaces.
Asphaltene agglomerations cause sludge build-up
Flocculation
of asphaltenes occurs, not only from the natural oxidation and aging of
the fuel, but also as the result of mixing oils from different crude
sources. This can occur when blending fuels or mixing into a storage tank
that contains fuel.
Asphaltene solubility is
also affected by the aromaticity and the type (and
concentration) of resins in the blend components. When the fuel blend
components are mixed, the asphaltenes may precipitate and form a sludge.
A selection of some of our products:
BYCOSIN
DP99 001 is a combination of oil soluble dispersant/stabilizer and combustion catalyst
especially developed for heavy fuel oil
stabilization and combustion. Often the
asphaltenes in the fuel leads to flocculation, sedimentation
and combustion problems with soot and deposits as
a result. This product is also well suited for
bunkering and blending of heavy fuels in ports where fuel stabilization is
a problem. Additional applications exist when
oil sludge recovery is required as the product functions
as a powerful dispersant.
BYCOSIN DP 98014
is a highly concentrated organometallic additive for heavy fuel oils. The
product, which is neutral and oil soluble, is
especially effective at stopping high temperature
corrosion and deposit formation in power plant boilers. The 98014 contains
surfactants and stabilizers which are carefully selected
for their effectiveness in
dispersing and stabilizing asphaltenes in tall fuels.
