Abstract
Herein is disclosed a method and an apparatus for preparing a highly purified gas from a crude liquid comprising the gas and one or more of a metal, particulates, water vapor, or a volatile impurity. The method comprises: (a) vaporizing the crude liquid, to yield (i) a first vapor stream comprising the gas and (ii) a first liquid stream comprising the gas; (b) removing water vapor, particulates, or both from the first vapor stream, to yield a second vapor stream comprising the gas; (c) condensing the second vapor stream, to yield a second liquid stream comprising the gas; and (d) sparging the second liquid stream with an inert gas, to yield (i) a third vapor stream comprising the gas and (ii) a third liquid stream comprising the highly purified gas. Also disclosed is a method for preparing an adsorbent to effectively remove water vapor from the gas, as well as an adsorbent so prepared.
