Abstract:

This report results from a contract tasking Royal Military College of Science as follows The main objective of the proposed work is to examine candidate HITTs additives that have an ability to increase the electrical conductivity of hydrocarbons. In particular, the main emphasis will be on factors that adversely interfere with the conduction process and depress the conductivity response. The research program will aim to A establish baseline electrical conductivity for BP and Ethyl additives in a model hydrocarbon dodecane B examine the influence of the factors considered in A for JP-8 fuel C comparisons of model and real fuel behavior and consideration of the implications for in field behavior. To achieve this, measurements will be made to examine factors, which determine the magnitude of the conductivity response in the model hydrocarbon 1. The effects of concentration of HlTTs additives, 2. The effects of other fuel components on the behavior of HITTs additives. This will include naturally-occurring and refinery introduced components and certain coadditives, 3. The effects of certain physical properties of the bulk hydrocarbon and especially viscosity, on HlTTs additive behavior, 4. Additive batch-to-batch variation, 5. Incidences of conductivity dependence on time, 6. Influence of temperature, on conductivity for the working temperature range over which these additives will be used. Especially it is important to examine the temperature dependence of the most important observed effects, 7. There is evidence that certain HlTTs additives may cause the formation of microemulsions of water in fuel. The effects on electrical conductivity will be examined.
