Abstract
In one aspect of the present invention, a hydrocarbon trapping device is provided, including a conduit and an adsorbing element positioned within the conduit. The conduit includes a wall having a wall thickness and the adsorbing element has an adsorbing element thickness that is generally equal to or less than the wall thickness. Furthermore, the adsorbing element defines a leading edge, a trailing edge, and a flow path extending between the leading and trailing edges in a direction substantially parallel to a longitudinal axis of the conduit.
