<p>A process and apparatus for selectively removing a target liquid constituent from a multi-component liquid is described. The process comprises the steps of: a) heating the multi-component liquid in a chamber to a temperature at which the target liquid constituent selectively evaporates to form a vapor rich in the target liquid constituent; b) bubbling a carrier gas through the multi-component liquid of step a); c) continuously removing a gas/vapor mixture from the chamber, the gas/vapor mixture comprising the vapor from step a) and the carrier gas from step b); d) condensing the gas/vapor mixture of step c) in a condenser to form a condensate rich in the target liquid constituent and thereby liberate the carrier gas from the gas/vapor mixture; and, e) returning the carrier gas from step d) for use in step b).</p> |
