Fuel Oil Additives

Increasing fuel economics

Our range of fuel oil additives (FOA) is designed to improve refinery blend economics. The diverse additive portfolio adds stability to cracked component streams, allowing refiners to increase the proportion of lower cost streams in the finished pool of a middle distillate.

Reducing instability in cracked streams

Fuel instability is caused by a series of polymerization, acid-base and esterification reactions during refinery processing and blending, as well as during fuel storage. These reactions result in the degradation of fuel color and the formation of acids, gums and sediments.

These complex reactions are often catalyzed by the trace quantities of metals found in lower cost ‘cracked’ streams. Fuel instability is therefore a more significant issue when cracked materials are blended into the distillate pool.

Unstable fuels can have a variety of negative effects, including:

  • Filter blockages in distribution and vehicles
  • Damage to fuel lines and tanks
  • The formation of engine deposits

Stabilizing effect

Innospec’s FOAs stabilize heating oils, gas oils and diesel fuels by eliminating the formation of gums, insoluble residues and colored bodies.

The extensive range consists of core products, which have one main function, alongside more complex multifunctional packages.

The benefits provided by Innospec’s FOAs packages can be further extended by adding other additives from Innospec’s Fuel Specialties range. Products such as our corrosion inhibitors or metal deactivators can be incorporated into a FOA solution to meet specific refinery requirements.

Our team of experts can support refiners by developing customized solutions to their unique problems.

Innospec's FOA range includes core components and multifunction additive packages.

These packages offer the following benefits:

Our range includes:

FOA-3

Part of Innospec’s range of fuel oil additivesFOA-3 is widely recognized as the most cost-effective solution to stability problems in higher sulfur content distillate fuels. 

FOA-5

A core component in Innospec’s range offuel oil additives, FOA-5 effectively and efficiently disperses particulates and other insolubles formed by the oxidization of unstable fuel components

FOA-6

One of the core components in the fuel oil additives range from Innospec, FOA-6 has been developed to provide superior performance in severe fuel types. The additive prevents oxidization that would cause darkening and the formation of insoluble deposits in distillate fuels.

FOA-6 and all products containing FOA-6 are currently not available in the EU.

FOA-31A

This multifunctional solution from Innospec’s fuel oil additive range provides a unique combination of advanced dispersant, antioxidant/stabilizer, metal deactivator and dehazer.

FOA-35A

FOA-35 is member of the multifunctional range of fuel oil additive solutions offered by Innospec. It provides a combination of advanced dispersant, antioxidant/stabilizer, metal deactivator and corrosion inhibitor.

FOA-81

A core component in Innospec’s fuel oil additives (FOA) range, FOA-81 is formulated to minimize fuel/water interaction problems in service. Offering improved stability, dispersancy and sludge control, this FOA provides superior stabilization in a wide range of distillate fuels.
