Antimisting Kerosene. Evaluation of Improved FM-9 Additive.
Abstract
Optimization of FM-9 dissolution rate to attain both acceptable mist suppression and degradation properties within 15 to 20 minutes of in-line blending was carried out by Imperial Chemical Industries (ICI). This report discusses the evaluation of the FM-9 with improved dissolution rate and consequently better degradability characteristics for compatibility with engine filters and fuel control system. This additive was identified as a candidate additive to be used in a Control Impact Demonstration (CID) test. The major findings of the investigations are: 1) Quality fo the FM-9 slurry meets the metering and dispersion requirements for single stage, in-line blending. 2) The dissolution rate at ambient fuel temperatures (15-20 C) is sufficient, and produces AMK fuel with adequate fire suppression in 30 minutes after blending. 3) Freshly blended fuel can be degraded without difficulty with a specific power requirement of less than 30 kWsL-1. 4) Contamination with large amounts of bulk water leads to formation of gelled emulsion on the interface. The water vapor condensation of AMK surfaces produced a string-like second phase. 5) Low temperature evaluation indicated no phase separation and gel formation problems. 6) Significant loss in pumpability performance with FM-9 AMK was observed at both room and low temperature using the Cessna 441 boost pump. However, the deterioration of pumpability performance was not as significant with AMK as compared with Jet A using the DC-10 boost pump.
