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.
ACTIONS
OF THE “rb bertomeu”
ADDITIVES FOR
DIESEL OIL
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.
BENEFITS OF
THE “rb bertomeu” ADDITIVES FOR DIESEL OIL
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:

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
