摘要：Apparatus for extracting contaminants from a stream comprising a

contaminant-containing mixture of liquids and gases which comprises: (a) a contaminant-containing mixture input; (b) a vapor-liquid separator receiving the contaminant-containing mixture from the input and producing a liquid component stream at a firstoutlet and a gaseous component at a second outlet; (c) an optional first contaminantremoval system receiving the liquid component stream from the vapor-liquid separatorand producing a contaminant-free liquid stream; (d) a vacuum inducing device in fluidcommunication with the contaminant-containing mixture input and the vapor- liquidseparator and receiving said gaseous component from the vapor- liquid separator; (e) acooling element receiving the gaseous component at a first temperature from thevacuum inducing device and producing the gaseous component at a second temperaturefrom a first outlet and a condensed liquid component from a second outlet, said secondtemperature being lower than said first temperature; (f) a heating element receiving thegaseous component from the cooling element at said second temperature and

producing a reduced-relative-humidity gas component at a third temperature, said third

temperature being higher than said second temperature, said heating element having aheating jacket surrounding a conduit through which the gaseous component passesthrough the heating element, said heating jacket receiving a heating fluid from a first heatfluid conduit into a heating jacket input and outputting said heating fluid from a heatingjacket outlet into a second heating fluid conduit; and (g) an optional second contaminantremoval system receiving the reduced-relative-humidity gas component from the heatingelement and producing a contaminant-free gas; wherein the apparatus necessarilyincludes either the first contaminant removal system or the second contaminant removalsystem.
