Abstract:
1. A method for identifying additives for addition at any point in a jet fuel distribution system for the delivery of additized jet fuel with an acceptable water content, through a commercial dewatered jet fuel delivery process, such method comprising: (1) securing a sample of dry-unadditized jet fuel; (2) incorporating one or more of the additives being evaluated into the jet fuel sample; (3) securing an operable filter/coalescer cartridge of the type to be used in the practice of the commercial dewatered jet fuel delivery process; (4) circulating dry-additized jet fuel through the filter/coalescer to condition the filter/coalescer cartridge; (5) passing the dry-additized jet fuel through the conditioned cartridge at an initial controlled fuel flow rate to produce a fuel effluent; (6) measuring the water content of the fuel effluent; (7) metering water into the additized fuel at different rates to establish different water content levels in the additized fuel while flowing the fuel through the cartridge and monitoring the water content of the fuel effluent at the different additized fuel water content levels; (8) repeating steps 4 through 7 at a number of different fuel flow rates; (9) recording the additized fuel water content levels and fuel effluent water content levels at each of the different fuel flow rates; (10) determining whether the additized fuel at any water content level at the different flow rates gives an effluent fuel meeting the acceptable water content level; (11) making a plot of the wet-additized fuel flow rate versus the additized fuel water content level values for those additized fuels that yield an effluent fuel meeting the acceptable water content level; (12) determining from the plot the additized fuel water content levels and fuel flow rates that produce dewatered additized jet fuel; (13) determining the acceptability for addition at any point in the jet fuel delivery system the additive or additives whose presence in the jet fuel will not prevent the filter/coalescer cartridge from dewatering the wet-additized fuel to an acceptable water content level at an acceptable fuel flow rate.
