<p>A high efficiency process and apparatus for extracting condensable vapors from a gas stream using a vortex tube expansion is disclosed. The process comprises partially condensing in a high pressure condenser (14) a raw feed high pressure gas stream in line (12) rich in condensable vapor by an exchange of heat with a cooling medium in line (16) comprising a cold exhaust stream from a vortex tube (18); separating condensate from the raw gas stream in a separator (22) to produce a raw lean gas stream in line (26); expanding the raw lean gas stream in the vortex tube (18) to produce the cold exhaust stream and a hot exhaust stream in line (36); and preferably ejecting the cold exhaust stream in line (38) with the hot exhaust stream in an ejector (40) to increase pressure differential through the vortex tube (18).</p> |
