Crude oil having substantial amount of organic acid, in particular, naphthenic acid compounds is contacted with supercritical water and a catalyst for deacidification.
A process removes naphthenic acid and/or naphthenic compounds from an aqueous solution.
A system for removing naphthenic acid and/or naphthenic compounds from an aqueous solution is also disclosed herein.
The present disclosure provides the use of a biomass-derived aromatic material as a sorbent for naphthenic acid.
The method includes adding an effective amount of a high molecular weight naphthenic tetra-acid to the base crude oil to form a crude oil mixture and feeding the crude oil mixture to a crude oil refinery component.
