Abstract

Described herein are methods and systems for performing liquid-liquid extraction in bulk tankage. According to certain embodiments, the liquid-liquid extraction can occur in a bulk tank via a circulation loop, in which a solvent mixture is injected with the hydrocarbon ahead of mix valves on the circulation loop. According to other embodiments, a misting system is installed in the vapor or head space of bulk tankage. The misting system distributes small micro-drops of a solvent mixture so as to cause a uniform lay down over the entire top surface area of hydrocarbon. The solvent mixture migrates from the top surface of the hydrocarbon to the bottom of the bulk tank, reacting during migration to cause liquid-liquid extraction.

IPC Classes  ?

• C10G 19/02 - Refining hydrocarbon oils, in the absence of hydrogen, by alkaline treatment with aqueous alkaline solutions
• C10G 5/04 - Recovery of liquid hydrocarbon mixtures from gases, e.g. natural gas with liquid absorbents
• C10G 61/04 - Treatment of naphtha by at least one reforming process and at least one process of refining in the absence of hydrogen plural serial stages only the refining step being an extraction
• C10G 21/16 - Oxygen-containing compounds
