Q Can Stanadyne’s
diesel fuel additives be used in bulk storage tanks? A All
Stanadyne diesel fuel additives are suitable for use in bulk
storage application. However, the conditions under which it
is added to the storage tank will have an impact on the rate
at which it is dispersed. The level of homogeneity of additive
in the tank depends on several factors such as temperature of
the base fuel & additive, the size of the bulk storage tank,
the degree of agitation in the tank, etc. If there is mixing/agitation
in the storage tank, then the additive will be homogeneous and
remain that way. However, if there is no mixing/agitation the
level of dispersion in the storage tank will be an unknown variable
as the rate of dispersion depends on the factors listed above.
To obtain proper dispersion in a bulk storage tank, add the
recommended ratio of fuel additive to the tank prior to adding
the fuel. The addition of the base fuel will provide the necessary
mixing/agitation. At the end of fueling, the mixture in the
fuel tank should be homogeneous.
