Dyes are often added to fuels for tax purposes, but they cause degradation of the fuels. It would be advantageous to remove the dyes prior to their use in critical aerospace applications. Current technologies vary in the efficiency with which they can remove unwanted dyes from fuel sources. We have used Hansen Solubility Parameters to develop an “ideal solvent” that can be used to extract these dyes from fuel. This will also be applied to removal of sulfur compounds from fuels. Sulfur compounds in fuels create sulfates during combustion, which in turn react with water to make sulfuric acid. Sulfuric acid damages engine components and the environment. Thus, this research could lead to great benefits for both the environment and the aerospace community.
