In fuel systems, steel piping and storage vessels can corrode and rust when both water and air contaminate the fuel. Water can contaminate fuel through refinery processes such as water washing, caustic processing, salt drying or through condensation of water from the air. Entrainment of air during pumping, mixing or blending operations can introduce oxygen that contributes to corrosion.
Nalco Water provides corrosion inhibitors for protection of both ferrous metals used in automotive, industrial and commercial fuels, as well as corrosion inhibitors for specialized applications such as fuel transport pipelines, aviation gasoline, military and civil jet fuel, and ethanol.
The proper application of corrosion inhibitor into a fuel system is critical, and that process differs in new versus existing or aged systems. Knowing the acceptable rates of corrosion inhibitor permitted in specific applications and the best point in a process to treat fuel with corrosion inhibitor are also of critical importance. Contact your Nalco Water sales rep for more information about treating your specific system.
