Vent ice prevention method |
| 摘要 |
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. |

1. An improved vent ice prevention method comprising the steps of:
introducing a cold vent stream into a first conduit, wherein at least a portion of said first conduit is concentric with a second conduit, thereby producing an annular region; introducing a hot vent stream into a third conduit, wherein said third conduit is in fluid connection with said annular region; and expelling 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 thereby preventing said first conduit from forming condensation and/or ice at an exit of said first conduit while the hot vent stream is flowing through said annular region. |
