Inlet vane device and vessel containing same

A vane inlet device is provided in a vessel to receive and redistribute a fluid stream entering the vessel and to facilitate separation of liquid from the fluid stream. The vane inlet device includes a passageway bounded by a top plate and a bottom plate spaced from the top plate. First and second arrays of vanes extend between the top and bottom plates and are positioned to receive respective portions of the fluid stream flowing from an inlet end of the passageway toward an opposite end and redirecting it out opposite sides of the passageway. A spacing between the first array of vanes and the second array of vanes progressively decreases in a direction from the inlet end of the passageway toward the opposite end. A beam extends from the top plate to the bottom plate between the first and second arrays of vanes to reduce flexure of the top and bottom plates and to separate the respective portions of the fluid stream.
