Abstract: One exemplary embodiment may be a distribution tray for a vessel. Generally, the distribution tray includes a member, a compartment, and an insert. The member can form a first side and a second side. Typically, the first side is adapted to receive a liquid thereon. Additionally, the member can form a plurality of openings. Usually, the compartment extends through the member with a first portion protruding from the first side and a second portion protruding from the second side, and is adapted to permit the passage of a fluid there-through. The insert may be positioned within the compartment to constrict and then expand the passage of the fluid there-through.

Abstract: The present invention provides for a gas mixing device and its use in a catalytic partial oxidation reactor. The gas mixing device is typically an eductor such as a venturi-type eductor which will mix the feed gases used in the catalytic partial oxidation process. Two gas mixing devices may be used in sequence.

Abstract: The present invention relates to a process for removing nitrogen oxides, sulfur oxides, mercury and mercuric oxide from gas streams such as furnace or utility boiler flue gas streams, particularly those derived from coal-fired utility boilers, or from a gas stream from another pollutant abatement process. Ozone will react with the impurities in the gas stream to form mercuric oxide and higher oxides of nitrogen which can be removed by scrubber means. Additionally, and alternatively, the present invention provides for the use of ozone and ultraviolet radiation to remove nitrogen oxides, sulfur oxides and mercury from gas streams.
