Abstract

Small quantities of one or more liquids having a low boiling point dispersed with a large quantity of one or more immiscible liquids having a higher boiling point are separated in a rapid and efficient manner. A non-reactive gas (nitrogen, helium, air, or combinations thereof) is heated by recycled energy and make-up energy to a temperature above the boiling point of at least one liquid but below that of at least one other liquid. The heated gas is combined with the unheated or preheated liquid-liquid mixture to be separated, and the liquid-gas blend is mixed, heated and distributed by an improved heat exchanger having thermal conductive gas tubing, metal wools and fins) and nebulizer, forming a mist inside a vessel containing a pool liquid of at least one liquid having a boiling point higher than that of at least one other liquid, which pool liquid has been heated with at least a heat pump means to a temperature above the boiling point of at least one liquid but below the pool liquid's own boiling point. The liquid having high-boiling point in the mist settles by gravity and merges with the pool liquid. The vapor of liquid having low-boiling-point in the mist is collected, condensed and recovered with a condensation means. The resulting fractions of each component are then collected separately.
