Abstract
An improved vent ice prevention method including introducing a cold vent stream into a first conduit, wherein at least a portion of the first conduit is concentric with a second conduit, thereby producing an annular region, introducing a hot vent stream into a third conduit, and wherein the third conduit is in fluid connection with the annular region, thereby preventing the first conduit or the second conduit from forming ice. The cold vent stream is a cold compressor seal vent stream. The hot vent stream is a warm compressor seal vent stream.
