Abstract:
1. A system for separating high molecular weight gases in an exhaust stack from an exhaust gas of a combustion source comprising: a blower attached to an intake of the exhaust stack to receive the exhaust gas from the combustion source and create a tangential flow of the exhaust gas within the exhaust stack, wherein the blower imparts sufficient centrifugal force on the exhaust gas to concentrate the high molecular weight gases along the inner surface of the exhaust stack; an interior vent within the exhaust stack that collects the high molecular weight gases concentrated along the inner surface of the exhaust stack, the interior vent comprising (i) a vent wall having a top portion attached to the interior surface of the exhaust stack along the entire inner perimeter of the exhaust stack and a lower portion that extends downward into the exhaust stack to form a gap between the vent wall and the interior surface of the exhaust stack, and (ii) at least one opening in the interior surface of the exhaust stack between the top and bottom portions of the vent wall; and a transfer pipe connected to the at least one opening in the interior surface of the exhaust stack to remove the high molecular weight gases from the interior vent.
