Dual-Pressure Flare System and Method of Use

摘要

A dual-pressure flare system and a method of its use. The dual-pressure flare system includes a dual-pressure flare stack having a central axis that is aligned with the center of a high-pressure outlet; a high-pressure flue having a central axis that is co-linear with the central axis of the dual-pressure flare stack; and a low-pressure flue connected to a low-pressure tip. Some exemplary embodiments of the system further include an air-assist assembly having an air-supply connection connected to an air blower and a mixing chamber, wherein the mixing chamber surrounds the low-pressure tip. In some exemplary embodiments, the air-supply connection is disposed outside the dual-pressure flare stack and the high-pressure flue.

主权项

1. A dual-pressure flare system comprising:
(a) a dual-pressure flare stack comprising a central axis, a high-pressure chamber having a high-pressure gas inlet, a high-pressure gas outlet, and a center aligned with the central axis, and a low-pressure chamber having a low-pressure gas inlet and a low-pressure gas outlet, the low-pressure chamber in vertically stacked arrangement to the high-pressure chamber; (b) a high-pressure flue comprising a central axis that is co-linear with the central axis of the dual-pressure flare stack, a first end connected to the high-pressure gas outlet, a second end connected to a high-pressure tip; and (c) a low-pressure flue comprising a first end connected to the low-pressure gas outlet, a second end connected to a low-pressure tip.
