International Classification:

C22B 6000

US Classification:

75398

Abstract:

A method and apparatus producing halogenated products from metal halide feeds. In one embodiment, uranium hexafluoride is treated by separating fluorine from the metal of the uranium hexafluoride. Uranium hexafluoride is introduced into a molten metal bath under conditions whereby the uranium hexafluoride in the presence of hydrogen and oxygen can react to form a uranium dioxide and anhydrous hydrogen fluoride. The anhydrous hydrogen fluoride is removed from the molten metal bath as a gas stream and the uranium dioxide is discharged as a ceramic phase.

Abstract:

Provided is a dual spray nozzle tip assembly having a geometry that is split into several sub components to enable robust manufacturing and assembly of the resulting nozzle. The nozzle tip assembly is configured to be attached to a device configured to provide a pressurized fluid and gas therefrom. The nozzle tip assembly comprising an elongated body defining a fluid lumen and at least one gas lumen between a distal end and a proximal end. The elongated body including at least an attachment profile, a straight portion, and an outlet region. The outlet region defines a shear nozzle in communication with the fluid lumen and at least one gas outlet in communication with the at least one gas lumen, the outlet region is configured to direct pressurized gas from the at least one gas outlet and to produce a desired spray pattern from the shear nozzle.
