REDUCING THE FORMATION OF FUEL OIL SLUDGE
CUTS FUEL CONSUMPTION,
REDUCING OPERATING COSTS

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" provides several well-known advantages, including 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 obtained in two cogeneration installations with Diesel engines (with a low initial level of sludge, around 8 Kg per metric tonne of fuel oil), using the additive "rb bertomeu" beco F1/ASF:
                                                                   MSM Plant        COOSUR Plant
                                                               
(Deutz engines)    (Wärtsilä engines)
Reduction in sludge obtained (%)                - 58.83 %                  - 54.84 %

This reduction represents a reduction in consumption of fuel oil of 0.45% and a reduction in the costs of removing and treating sludge of 57% of an orientative cost of 130-170 Euros per metric tonne of sludge generated in terrestrial plants and 30-40 Euros per metric in Marpol marine (ships).
