normally contained in Diesel fuel may increase due to the
condensation of water vapour contained in the air present
inside the storage tanks, both in industrial storage tanks and in the tanks
of vehicles or watercraft.
fillings of the tanks, when the air inside them is renewed
with air from outside, the condensed water vapour either
mixes with the Diesel fuel, or gradually accumulates at the
bottom of the tank. The amount of water collected can be
higher than may be supposed, reaching approximate values
of one litre of water after ten fillings in a tank of
10 m3 (double for a tank of 20 m3, and so on).
of water in Diesel fuel and the accumulation of water in
the tank should be minimised to avoid the two types of problem
Seizures in injection systems in Diesel engines, whether
large or small.
The formation of algae and/or bacteria that foul the tanks
and block filters in the fuel line.
In order to
prevent these problems, it is necessary to decant the water
and remove it by bleeding the tank, so that the water neither
mixes with the Diesel fuel to be consumed nor accumulates
in the tanks, as it would lead to the proliferation of algae
and bacteria in the aqueous component of the fuel. If the
water cannot be separated effectively, the use of bactericides
and/or fungicides becomes necessary in the majority of
Diesel fuel that favour the de-emulsification and decanting
of water (in addition to other benefits) , like additives "rb bertomeu"
"beco" series for Diesel oil, are
recommended for maintaining the injection systems in good condition.
