These aerodynamic separation nozzles utilize a combination of aerodynamic forces and separation nozzle structure to induce large centrifugal forces on the fluids that in combination with the structure of the nozzle are used to separate heavier constituents of the fluid from lighter constituents, and more particularly to separate a first or liquid phase from gaseous phases. In some embodiments a number of separation nozzles are combined into a single system suitable for dynamic processing of a process gas. In other embodiments the separation nozzles are temperature controlled to condition the incoming gas to a temperature in order to encourage a phase change in certain constituents of the gas to occur within the nozzle to further enhance separation.

A centrifugal mesh mist eliminator generally comprises a cylindrical roll of mesh attached to a vertical rotating shaft positioned within the center of a pressure vessel. A horizontal partition within the pressure vessel forms a barrier seal between the upper and lower portions thereby directing droplet laden gas flow through the rotating mesh. The incoming droplet laden gas stream enters the lower portion of the pressure vessel through an inlet nozzle. The droplet laden gas stream flows through the rotating cylindrical mesh element where it enters the top section of the pressure vessel. Droplets impinge on the mesh and coalesce into larger diameter drops. These larger diameter drops detach from the mesh due to centrifugal force. The detached liquid droplets settle to the bottom of the vessel as their mass is sufficient to overcome the surrounding flow stream drag force. Liquid discharges from the bottom of the vessel through an outlet nozzle while dry gas exits through a top outlet nozzle. 1.
