Jet fuel, also known as kerosene, is designed for use in aircraft powered by gas-turbine engines. The product is subject to the extremely strict quality requirements. Particular focus in the quality standards is given to determination of fuel corrosion activity and water content in the fuel.
Such focus on the corrosion activity of the fuel is made in addition to the usual requirements applied to its fractional composition. The majority of methods used for the quality determination purposes simulate certain corrosion-ideal conditions at which the fuel is tested by using the active metals, i.e. copper and aluminum. This is also the reason to demand the producers for indicating what part of the product has been subject to the process of hydrotreatment.
Furthermore, it is important to note that Jet fuel probably is the only product which is subject to setting of the quality requirements before introduction of any additives. Special antistatic additives help reducing the accumulation of static charge during the loading to minimum.
Determination and limitation of water content in Jet fuel is also of major importance. Water content is determined following several different methods, while the additives which remove the water dissolved in petroleum products are introduced directly before jet fueling.
