Extraction of peroxide treated petroleum streams

摘要

This invention relates to a method for generating peroxides in petroleum streams and extracting oxidized sulfur and nitrogen compounds. Peroxides are generated in-situ by combining the petroleum stream with a high neutralization number (HNN) crude and adding an oxygen-containing stream. Alternatively, the oxidation of sulfur and nitrogen compounds may be accomplished by adding peroxides in the presence of oil soluble metal catalysts. The peroxides oxidize nitrogen and sulfur compounds in the petroleum stream to more polar compounds which are solvent extracted.
