Extraction is also called solvent extraction or liquid-liquid extraction (to distinguish it from solid-liquid extraction, that is, leaching), also known as extraction (commonly used in the petroleum refining industry). Component or multi-component solution, to realize the mass transfer separation process of component separation, is a widely used unit operation. Common extraction machines include ultrasonic extraction machines, microwave extraction machines, centrifugal extraction machines. The extraction machine uses the difference in solubility or partition coefficient of the compound in two immiscible (or slightly soluble) solvents to remove the compound from one solvent. Transfer to another solvent.
