All types of
fuel oil produce sludge during storage, due to their composition, processes of ageing and polymerisation. This sludge contains high proportions of hydrocarbons of high
molecular weight (asphaltenes, etc.) which are perfectly combustible
but which become separated from the fuel oil at the bottom of the storage
tank or in the fuel filtration and purification system. In both cases they are not utilised as fuel;
moreover, they need to be removed and then disposed of by a specialised
company. All these factors result in a loss of fuel, and in
the majority of cases, the additional costs of removing and treating the
sludge formed.
The treatment of fuel
oil with additives from "rb bertomeu"
in addition to several well-known advantages, provides a significant reduction
in the usual levels of formation of sludge.The treatment should be applied to the fuel oil storage tank in
order to obtain maximal efficacy of the components of the additive.
Actual results
demonstrating the reduction in fuel oil sludge achieved in two cogeneration
installations with Diesel engines (with a low initial level of sludge,
around 8 Kg per metric ton of fuel oil), using the additive "rb bertomeu" beco F1/ASF:
| |
MSM plant |
COOSUR plant |
| |
( Deutz engines) |
(Wärtsilä engines) |
| Achieved reduction in fuel sludge (%) |
58,83% |
54,84% |
| Achieved reduction of motor oil sludge (%) |
|
26,80 % |
| Achieved reduction in fuel sludge and motor oil per MT of consumed fuel oil |
4,32 Kg/MT |
5,80 Kg/MT |
These reductions in fuel oil sludge have a decrease in the consumption
of fuel oil in the plant of 0.45%. The reductions in fuel and oil sludge
represent a decrease in sludge of 5.80 Kg / MT of fuel oil consumed at
the plant. The previous value affects a reduction of 0.58 €
/ MT of fuel oil consumed due to a lower cost of sludge removal.These
values are valid for both the sludge removed in land plants and for marpol maritime,
at an average withdrawal price of 100 €/MT (theoretical value taken as a calculation
hypothesis).
