Originally diesel fuels were produced from straight run components having good stability characteristics.
During the last few decades the need to meet increasing middle distillate supply needs has led to the increased use of unstable cracked components in diesel fuel. Cracked components are higher in olefin content and are more prone to oxidation by free radical reactions.
This has resulted in the introduction of oxidative stability specifications and the increased use of additive stabilisers to enable refineries to cost effectively meet these specifications.
Key Performance Benefits
HiTEC® 4238 is a powerful diesel fuel stabiliser developed to provide enhanced oxidatitive and thermal stability for both diesel fuels and heating oils.
HiTEC® 4238 finished fuel additive will improve the storage and thermal stability of diesel fuels and heating oils leading to a reduction in sediment and gum formation.
HiTEC® 4238 will allow refiners to cost effectively meet specification requirements for fuel stability and has the additional benefits of:
Stabilising the fuel to control sediment and gum
Aiding colour stability
Minimising fuel filter blocking
Allowing refineries to maximise unstable blending streams into higher value finished products
Treat-rates may vary depending on the base fuel and stability specification requirement, however HiTEC® 4238 should be used in the range of 50 - 200 ppmv. Please contact your Afton Chemical representative for specific recommendations.
