Methods and Compositions for Deactivating Organic Acids in Oil

摘要

Certain metal and metal-like hydroxides may be added to hydrocarbons with an immiscible and/or more volatile non-hydrocarbon phase to reduce the acidic potential of hydrocarbons with respect to downstream storage, transport, and processability once the non-hydrocarbon phase is removed. These metal hydroxides reduce TAN stoichiometrically and permanently while improving the demulsibility of the oil. A particularly effective metal hydroxide is lithium hydroxide and a particularly easy solvent to remove is water.
