Abstract
A method for extracting and separating extractive components from fluids is provided. A first fluid and an extraction fluid are added to a vessel, thereby creating a two-phase two-layer system, wherein the first fluid and the extraction fluid are discrete and the two-phase system has a first fluid/extraction fluid interface. The two-phase system is then agitated, wherein the first fluid phase and the extraction fluid phase remain as substantially discrete layers. A means for communication between the first fluid and the extraction fluid is provided. The communication of the phases results in the extractive components being extracted from the first fluid into the extraction fluid. Agitation is stopped and the first fluid is recovered having reduced extractive components.
