Abstract:
1. An improved vent ice prevention apparatus comprising: a first conduit configured to receive a cold vent stream, the first conduit having an inlet and an outlet, wherein said cold vent stream comprises a cold stream originating from a cold compressor; a second conduit surrounding at least a portion of the first conduit thereby creating an annular region between the second conduit and the first conduit, the first conduit having an inlet and an outlet; and a third conduit in fluid communication with the annular region, wherein the third conduit is configured to receive a dry purge stream and introduce the dry purge stream to the annular region, thereby preventing said first conduit or said second conduit from forming condensation and/or ice, wherein the first conduit and the second conduit are configured to expel the cold vent stream and the warm vent stream to the atmosphere at a direction that is substantially along the axis of the first conduit.
