ABSTRACT:
In crude oil fractions, fossil fuels, and organic liquids in general in which it is desirable to reduce the levels of sulfur-containing and nitrogen-containing components, the process reduces the level of these compounds via the application of sonic energy. The process can be performed both with and without the added presence of an oxidizing agent, and with or without elevated temperature and/or pressure. The invention is performed either as a continuous process or a batch process.
