N2 - Though it is generally known that a surface area to volume ratio (SA/V ratio) has a bearing on long-term storage stability of jet fuel, little real field data exists on this subject. In this field study, the stability of jet fuel stored for 2 to 10 years in 30 liter, 10m3, 300m3, 30,000m3 tanks and in a 150 km section of 16 pipeline, has been evaluated in relation to impact of SA/V ratio. The tests performed included the general specification requirements, long-term storage evaluation tests and microbiological tests. The data suggests that straight run jet fuel may be safely stored under good housekeeping conditions for ten years in carbon steel or stainless steel made storage tanks, having a SA/V ratio less than 3. Contrary to that, storage of straight run jet fuel, for only two years, in an underground 150 km section of 16 carbon steel pipeline, having SA/V ratio of 10, went off spec regarding existing gum. The storage conditions in this pipeline supported accumulation of water and rust particles in topographically low sampling points that could have contributed to the deterioration process. In small aluminum made tanks bearing SA/V ratio higher than 20, JFTOT deteriorated within several months of storage. This study sets a basis for an initiative to collect more historical data on this subject from various sources. A broader data base will enable to determine a solid numeric indicator to be used for decision making, regarding strategic storage of jet fuel in remote locations, based on volume, structure, construction materials and design considerations.
