Navy Coalescence Test on Petroleum F-76 Fuel with Infineum R655 Lubricity Improver at 300 ppm.

摘要

The Navy Coalescence Test (NCT) is a fit-for-purpose test which uses a specially manufactured small filter/coalescer cell to simulate the performance of a full scale filter/coalesce system while utilizing a small volume of fuel. This testing is designed to predict the performance of the filter/coalescer systems currently in use in the fleet. Many diesel fuels are used in applications which require them to lubricate fuel wetted parts. To improve the lubricity of a diesel fuel specific additives are added into the fuel. One such additive, Infineum R655 was tested in a base fuel of petroleum F76 which is reported here. The additized fuel performed as well or better than non-additized F76 in the NCT. Therefore it is recommended to continue with additional fit-for- purpose testing.
