ABSTRACT:
A vapor collecting apparatus for extracting a condensed, liquefied volatile component carried by a solvent gas. The apparatus includes a single cryogen-cooled vessel into which the gas stream is introduced, along with a flow of liquid cryogen, preferably liquid nitrogen. The output from the vessel contains droplets of condensed vapor which are separated from the gas solvent in a cyclone separator.
