The “rb bertomeu” additives for diesel 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 from the beginning. In facilities where there is no metering pump, we can supply the additive after making a study and in agreement with the plant manager. In the case of mobile equipment (cars , trucks , machinery , etc.) , in which the addition of the diesel oil is carried out directly into the fuel tank of the vehicle , it must be added before refilling to achieve a good mixture. This includes the addition of antifreeze .

 In industrial facilities it is possible that some of the additives will be added and metered in the feed line of the diesel oil to the combustion equipment or to the day tank. Each case must be analysed separately, taking into account the aims which  are desired by the addition to the fuel, if the additive is put in the line the effects of the separation of water and sludge in the storage tank are lost. In the case of antifreeze additive, this must be always added to the tank, as is logical and evident, since it makes no sense to treat diesel oil which is about to be injected into combustion equipment.



The immediate actions of the “rb bertomeu” additives for Diesel oil in the fuel storage tanks or in the fuel tanks of the vehicles are the following :

1-    De-emulsion and separation of the water present in the diesel oil. In storage tanks this water can be removed from the tank through periodic drainage, directly or through a pump, while in vehicles , boilers or facilities with in line filter and centrifugal separator it is eliminated systematically when the diesel oil is taken to the point of consumption.   In this way , the water , being eliminated, does not damage the injectors or cause lost energy or power due to its vaporisation during the combustion of the diesel oil in the engine , furnace , etc. Also , the sodium present in the water is eliminated , as well as its corrosive effects during combustion , although in very low quantities.

2-    The quality loss , oxidation processes which  by polymerisation (due to the action of the time , temperature and the presence of small quantities of water) allow the formation of rubbers and which normally is the cause of the appearance of sludge, also is avoided with our treatment of addition  to the general storage tank or to the fuel tank of the vehicle.

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

1-    The fuel filters stay clean of rubbers and resins , stopping solely solid impurities (not fuel) which the diesel oil could accidentally contain. This reduces, considerably , the need to change or clean filters as well as the temporary pressure loss in injection.

2-    The fuel injectors , in the case of the diesel engines , do not seize up because of the action  of tiny drops water , as this has already been decanted by the action of the additive and separated through the adequate mechanism (pumping , centrifugal separator, etc.), neither are they obstructed due to the action of rubbers and resins whose formation and presence has been avoided by action of the additive in the fuel tank. This results in a greater duration of the injectors and a better pulverisation of the fuel, avoiding the typical seizures and injector droplet leaks or injection at very low pressure.

3-    The head of the burners , where the diesel oil is pulverised and mixed with the air in the case of furnaces or boilers, stay free of adhered carbonous residues (absence of coking) , achieving a constant pulverisation, a uniform flame and avoiding, in a similar way to the injectors, the typical droplet leaks or injection at very low pressure, which cause unburned fuel.

4-    In the case of diesel engines as in burners, the combustion improves due to the presence of surfactants which  optimise the atomisation of the fuel and consequently its mixture with the combustion air. This, combined with the prior actions of cleaning injectors and heads of pulverisation, insures a perfect and continuous combustion. Due to this the level of CO in the exhaust gases is reduced and they are no unburned hydrocarbons in these gases , improving the energy efficiency and producing a fuel saving to achieve the same energy or to develop the same power. 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 (or hot water in domestic boilers).

5-   In the case of engines, the carbonous residues from the combustion are eliminated. These residues, when there is no detergent action of the additive, are deposited partially in the exhaust valves, hindering a good closure and generating a power loss. This is especially important in the engines of vehicles and mobile machinery, which are submitted to constantly changing work loads. Through the action of the additive, the valves stay clean and the engine always delivers the required power.

In the case of boilers the residual fowling of the surface of the exchange pipes is reduced, which stay clean longer, maintaining the rate of heat interchange and optimizing the energy efficiency.

6-    If Diesel oil contains many less impurities than heavy fuel oil, there is no doubt that some types of diesel oil , above all the less refined , intended for use in industrial facilities , ship engines, etc. , contain important quantities of Sulphur, which during combustion is oxidised and transformed into SO2 and SO3. The greater the content in Sulphur , the greater the corrosion by acid in cold zones of the installation. On the other hand , some diesel can contain small quantities of metals which can form corrosive salts on combustion . The presence of Mg in the additive hinders the formation of corrosive salts and minimises the oxidation of SO2 to SO3  ( and the possibility of sulphuric acid condensation) minimising future corrosions in hot and cold zones of the engine and exhaust gases circuit.



As a consequence of these actions, which are promoted by the “rb bertomeu” additives during the period of storage of the diesel oil in the storage tanks and during its combustion in the engines or burners , a series from economic benefits are obtained of which the most important is the fuel saving:

1-    In installations with fixed Diesel engines, cogeneration or ships , where the engines are submitted to a methodical maintenance process,  the fuel consumption to produce a power unit is reduced by a minimum of 1.5 % upon comparing the same plant or installation using or not using our treatment. In the majority of the cases , the saving is already equal or superior to the cost of the additive , leaving the other benefits obtained as additional gain.

2-    In automotive or machinery engine, where normally the checks and maintenance are not so important as in the prior case, the saving in fuel is superior to 2-3 % , even reaching 5 % , or yet more , in very dirty engines or those lacking maintenance. This greater percentage of saving or consumption reduction is easily understandable in this case, because the improvement of combustion is added to greater use of the generated power due to the better condition of the exhaust valves which are generally inspected less in comparison with the large engines.

3-    In installations of hot air generation for production of steam or hot water , equipped with burners ,  the fuel saving , or consumption reduction to achieve the same capability of generation of steam or hot water, should be measured by adding the improvements owing to an optimum combustion to the better heat transmission in the interchangers because of the absence of adhered residues. Both effects , achieved through the action of the additive , can represent a global diesel oil saving  of 5 - 8%  to achieve the same energy production, with a minimum saving of 2-3% considering an new installation with the exchanger absolutely clean. Which  means , in these types of facilities, the diesel oil is burnt better and furthermore , the heat generated in the combustion is taken better advantage of. Here is the energy loss table in function of the degree of dirt accrued in the pipes of the boilers:

        Residues/Soot                                    heat loss                     Increased fuel
        in pipes (mm. thickness)                         %                           consumption %       

                0.8                                                8 / 12                              2 /  2.5

                1.6                                               12 / 24                           2,5 / 4.5

                3.2                                                20 / 48                             4 / 8.5

Other real benefits, detected in practice, are the following:

-       Reduction of the pollutant emissions of CO  and unburned hydrocarbons through the exhaust gases of engines or boilers.

-       Reduction of maintenance costs, in repairs and replacement of corroded parts (valves , turbos , conduits of exhaust  gases, etc.).

-       Reduction of cleaning costs of the diesel oil installation (filters , fuel tanks , etc.).

-       Greater operating time due to removal of obstructions , coking and cleaning of the combustion installation.

-       Reduction of cleaning necessities, in time and frequency, of the heat interchangers of the boilers.

-       Increase of the Service Factor of the fixed facilities,  by decrease of maintenance and cleaning stoppages.

-              Increase in available power in non-static engines (automotive and mobile machinery) , by greater use of the developed power
