SERVO® -DS: Novel Stabilizer for Distillate Fuels |
|
 |
 What
is diesel stabilizer? |
 |
Diesel stabilizer is a formulated package
that protects the diesel fuel from oxidation during storage
& use and also helps in neutralizing the acids formed during
combustion.
|
Is
diesel stabilizers required in hydrotreated fuels? |
|
Yes, however, the treat rate may vary
|
What
is the typical treat rate of diesel stabilizer? |
|
It varies from fuel to fuel. However,
typically it is used in the range of 10 - 25 mg/lit
|
What
is the composition of diesel stabilizers? |
|
It is proprietary information. However,
in general, formulations contain antioxidant, metal deactivators,
acid neutralizing agents, etc.
|
What
are the tests for checking the efficacy of diesel stabilizers? |
|
UOP 413 test is used for checking the efficacy of diesel stabilizers
|
Whether
all the refineries in the country use diesel stabilizer? |
|
Every refinery is supposed to add this
additive. However all IOC refineries are adding diesel stabilizer
in appropriate treat level
|
|
Is
IOC using their own diesel stabilizer of procuring from
local/international market? |
|
IOC uses its own product
|
|
What
is the commercial name of IOC's Diesel Stabilizer? |
|
SERVO®- DS

What
Happens to Fuel When it is Stored? |
|
Any fuel, be it gasoline, diesel, or
heating fuel, is made up of many different organic compounds.
These organic compounds are constantly changing over time becoming
new compounds that change the characteristics of fuel. The same
molecules that make up the best parts of gasoline can react
with oxygen and other elements in the environment and form new
molecules that build up to form gummy residues or varnish-like
films that can clog up passages in fuel lines, carburetors,
and injectors.
Some fuels are treated with oxidation
inhibitors to allow them to be stored for up to 3 months without
generating excessive deposits. Other fuels have no inhibitors
at all. In any case, storage of equipment requires some special
consideration for the fuel system.
|
Why
Can't These Problems be Avoided by Draining Fuel? |
|
One way to avoid most of these deposits
is to completely drain the fuel tank and fuel lines. This procedure
poses a number of problems. First, it is virtually impossible
to get every drop of fuel out of the system by simply draining.
In order to remove all fuel, lines must be blown out and dried,
or enough fuel will remain to cause problems. Second, draining
the fuel exposes the bare metal in the tank and fuel system
to air and moisture which, together, can result in the formation
of rust and corrosion and which can allow gaskets to dry out,
crack and shrink, leading to fuel leaks when the system is refilled.
Third, drained fuel is a fire and safety hazard and represents
an environmental problem. Properly disposing of this fuel is
difficult. For these reasons, draining is not the solution.
|
Does
Fuel Stored in a Tank or Can Cause Problems? |
|
Fuel stored in cans or tanks will also
oxidize with many of the "bad acting" unstable molecules
remaining in the solution. Using this fuel next season, greatly
increases the likelihood that deposits will form in fuel systems
while the equipment is used. In other words, stored fuel needs
treatment too.
SERVO®-DS is a blend of
scientific additives all of which act together to prevent fuel
from undergoing degradation and oxidation during prolonged storage.
SERVO-DS acts as a protective wrapper around fuel molecules
so they cannot combine with oxygen or other molecules to form
new "bad actor" molecules. The "sweetened"
fuel will perform its job thereafter as though it had just been
freshly pumped into the fuel tank straight from the refinery
pipeline.
