Rapid Test Method to Quantify Corrosion Inhibitor Lubricity Improver Fuel Additive

Description:

TECHNOLOGY AREA(S): Ground Sea 

OBJECTIVE: Develop a portable instrument or method for the rapid measurement of corrosion inhibitor/lubricity improver in military fuel. 

DESCRIPTION: In certain field situations the Army is required to field additize commercial jet fuel with military fuel additives to make it acceptable for use in military air and ground equipment [1]. The Army would like to develop a light weight portable instrument or simple field method for the determination corrosion inhibitor/lubricity improver additive concentrations in military fuels. Analysis of fuel additive concentrations is critical to the Army for ensuring the proper additive levels during fuel distribution and in the additive injection processes, as too much or too little additive can lead to mechanical and fuel stability problems. Instrumentation must be portable and able to operate off battery power in field conditions, total weight for the solution will be under 10 pounds. The threshold ability of the instrument/method is being able to detect and quantify corrosion inhibitor/lubricity improver (0 – 36 ppm) [2] as required in JP-8 fuel [3]. Additional objective detection goals for the instrumentation/methodology include the detection and quantification of static dissipater (quantity to be able to provide a measurable conductivity between 0 – 1050 picosiemens per meter), fuel system icing inhibitor additives (0 – 2250 ppm) [3], and incidental contaminants. The Army’s goal is to use the device for testing fuel samples and/or monitoring fuels for correct additive levels to ensure the proper function of fuels. 

PHASE I: Develop an approach for the design of a portable analytical instrument(s) that is capable of analyzing fuels to determine the concentration of corrosion inhibitor/lubricity improver and other fuel additives. Conduct proof of principle experiments supporting the concept and providing evidence of the feasibility of the approach. 

PHASE II: Develop, build, and demonstrate a prototype portable analytical instrument(s) or methodology that is capable of analyzing fuels to determine the concentration of corrosion inhibitor/lubricity improver and other fuel additives. The prototype shall be delivered to the government. 

PHASE III: Technology developed under this SBIR could have a significant impact on commercial and military fuel distribution and field additive injection processes, the intended transition path is into the Army’s Petroleum Expeditionary Analysis Kit or alternatively the Petroleum Quality Analysis System - Enhanced.
