The “rb bertomeu” additives for heavy fuel oil should be added to the fuel storage tank to obtain all the benefits which  are expected of the treatment. In this way, the fuel is prepared for use in the corresponding combustion equipment and to obtain the maximum efficiency .

The addition must take place, in industrial facilities, at the moment of unloading the fuel into the storage tank via a which injects it into the unloading line. This guarantees a perfect homogenisation of the fuel additive mixture with the fuel oil from the beginning. In facilities where there is no metering pump, we can supply it after making a study and in agreement with the plant manager.

Only when it is to obtain partial benefits, mainly related to corrosion reduction, it is possible which  some of the additives will be injected and metered in the fuel  oil feed line of the combustion equipment or to the daily consumption tank. Each case must be analysed, taking into account the benefits which  are desired from the additive


The immediate actions of “rb bertomeu” additives for heavy Fuel oil in the fuel storage tanks are the following :

1-    De-emulsion and separation of the water present in the fuel oil. This water must be removed from the tank through periodic drainage. In this way part of the sodium present in the fuel oil is eliminated, as well as its corrosive effects during combustion. Also, being the water eliminated, it does not damage the injectors nor is power lost in its vaporisation during combustion.

2-    The hydrocarbons in suspension , solids or semi solids , of high molecular weight and are always present in the heavy fuel oil, they are disintegrated, dispersed and maintained in homogeneous suspension , avoiding the separation of organic sludge in the tank. This avoids the sludge building up in the tanks , the loss of fuel material, the cumbersome operations of tank cleaning and the costly withdrawal of sludge by specialised contractors.

3-    The degradation due to the action of the time and temperature (polymerisation) , which is normally the cause of the appearance and separation of more and more sludge in the heavy fuel oil tanks, this is also avoided with our additive treatment  to the storage tanks.

The improvement actions of  “rb bertomeu” additives for heavy Fuel oil, in the engines and burners of boilers or furnaces , are the following when the treated fuel oil is used and consumed in the corresponding plants:

1-    The fuel  oil circuits, are maintained cleaner for long time periods due to the lower quantity of sludge, including purifiers and filters. In the case of Co-generation Plants , according to the experience of our clients , the opening times of the purifiers can be delayed to the maximum permitted by the program  and the automatic filters (which  operate opening against pressure) remain almost without being opened due to the lower quantity of sludge.

For more information, please read our Bulletin No. 4: "The fuel oil treatment reduces the consumption in big engines operated with fuel oil. Data on savings obtained in two cogeneration plants"

2-    The combustion improves due to the presence of surfactants which  improve the atomisation of the fuel and consequently its mixture with the combustion air. Due to this, there are no unburned hydrocarbons in the exhaust gases, therefore improving the energy efficiency. In the case of diesel engines, this is especially important as the combustion time is limited, while in the case of boiler burners, the effect of the additive permits operation with least excess of air over the theoretic necessary and obtains some gases at greater temperature, which raises  the rate of heat exchange and the energetic efficiency of the boiler in the steam generation.

Bulletin No. 27: "Statistical data on analysis of combustion gases in cogeneration plants with diesel engines running on fuel oil"

3-        The chemical synthesis process by "rb bertomeu" produces the before-mentioned Fatty acids Organic salts completely soluble in hydrocarbons in which the magnesium particles are Mg2+ ions, with a radius of 72 picometers (1 picometer is 1,000 times smaller than a nanometer).

The surface reactivity of these magnesium ions over conventional materials (oxides and hydroxides of magnesium) is about 100 times higher.

The "rb bertomeu" additives with magnesium are the most reactive agents known to neutralize corrosion by Vanadium pentoxide and Sodium vanadates.

When burning fuel oil, a fuel with a large quantity of metal impurities, the “rb bertomeu” additive, that is composed by Magnesium Organic Salts SOLUBLE in HYDROCARBONS, instigates the formation of non-corrosive compounds with a high fusion point , avoiding the presence of low fusion point sodium vanadates, which are mainly responsible for corrosion in exhaust valves , turbo-compressors and other hot parts of the engines , the heat exchangers of the boilers,  etc. and also of the formation of residual encrustation in these elements.

Especially corrosives (due to its low fusion point : around 350ºC) are the sodium vanadates with V2O5/Na2O molar ratio = 3 , although other compounds with higher or lower molar ratio have fusion temperatures between 400º and 650ºC  and can be also dangerous in some points of the engine where theses temperatures are reached.

That action of fixing of heavy metals, is also translated in a decrease of the oxidation of SO2 to SO3 (formed from Sulphur in the fuel oil), by minimising its catalytic action on the reaction; as consequence, the appearance of sulphuric acid condensation when the combustion gases cool reduces and with this the cold corrosion.

Bulletin No. 29: "The reduction in emissions of soot and incrusted residues in steam boilers running on fuel oil"
Bulletin No. 5: "Minimizing incrustation on steam boilers reduces fuel consumption"
Bulletin No. 1: "Corrosion on exhaust valves and turbo-compressors in large engines running on fuel oil is preventable"

The corrosion which  appears in the turbo-compressors is produced , normally , over a longer time period than in the exhaust valves of the engines. Through years of experimentation in power plants, reliable data is being obtaining which indicates which  the regular use of  “rb bertomeu” additives notably increases the life of the turbo-compressors and reduces their cleaning necessities, run-time cleaning (by water injection, steam, dry milled vegetal shell , etc.), as well as in-depth cleaning of the dismantled equipment. This reduction of cleaning also means an important increase of the annual production of power due to the decrease in down time of dismantling and rebuilding turbos and to the minus time operating at reduced power , as is customary when cleaning is done during run time.
