Fluid dispersion unit with directional component vector
A valve-tray assembly and method for lighter fluid heavier fluid contact towers. The active area of the tray is constructed with valves having multiple lighter fluid discharge areas facilitating improved mass transfer efficiency. The valves include first and second support legs oriented in line with the heavier fluid flow with both legs and the valve top constructed with apertures wherein the heavier fluid may flow into engagement with the lighter fluid passing from beneath the tray up, through and out of the valve.
1. A tray valve assembly for a process column of a type wherein a first, heavier fluid flows downwardly from a downcomer onto a tray and thereacross in a first direction through which a second, lighter fluid flows upwardly therethrough for interaction and mass transfer with the first, heavier fluid before passing therefrom, the tray valve assembly comprising:
a plurality of tray apertures formed on a surface of the tray for facilitating the second, lighter fluid flow upwardly therethrough;
a plurality of floating valves disposed across the surface of the tray and mounted in association with the plurality of tray apertures formed on the surface of the tray, at least one floating valve of the plurality of floating valves comprising:
a top surface;
an upstream securement leg coupled to the top surface;
a downstream securement leg coupled to the top surface;
a first valve aperture formed in the downstream securement leg to facilitate the second, lighter fluid flow therefrom;
a first deflector tab disposed with the first valve aperture, the first deflector tab being pivoted outwardly from the downstream securement leg until the deflector tab is at least substantially parallel with the top surface, the first deflector tab being pivoted about an upper edge of the first valve aperture;
a second valve aperture formed in the top surface;
a second deflector tab disposed with the second valve aperture, the second deflector tab being pivoted outwardly from the top surface; and
the first deflector tab, the second deflector tab and an orientation of the at least one floating valve on the tray allowing the second, lighter fluid to be injected into the first, heavier fluid passing over the first valve aperture and the second valve aperture for inducing a turning flow of the first, heavier fluid.
2. The tray valve assembly of claim 1 , wherein the at least one valve is adapted to induce the turning flow of the first, heavier fluid to a less-irrigated portion of the tray.
3. A tray valve assembly for a process column of a type wherein a first, heavier fluid flows downwardly from a downcomer onto a tray and thereacross in a first direction through which a second, lighter fluid flows upwardly therethrough for interaction and mass transfer with the first, heavier fluid before passing therefrom, the tray valve assembly comprising:
a plurality of tray apertures formed on a surface of the tray for facilitating the second, lighter fluid flow upwardly therethrough;
a plurality of floating valves disposed across the surface of the tray and mounted in association with the plurality of tray apertures formed on the surface of the tray, at least one floating valve of the plurality of floating valves comprising:
a top surface;
an upstream securement leg coupled to the top surface;
a downstream securement leg coupled to the top surface;
a first valve aperture formed in the downstream securement leg to facilitate the second, lighter fluid flow therefrom; and
a first deflector tab disposed with the first valve aperture and being pivoted outwardly from the downstream securement leg until the first deflector tab is at least substantially parallel with the top surface, the first deflector tab being pivoted about an upper edge of the first valve aperture;
a second valve aperture formed in the top surface;
a second deflector tab disposed with the second valve aperture, the second deflector tab being pivoted outwardly from the top surface; and
the first deflector tab, the second deflector tab and an orientation of the at least one floating valve on the tray allowing the second, lighter fluid to be injected into the first, heavier fluid passing over the first valve aperture and the second valve aperture for simultaneously inducing directional flow of the first, heavier fluid in at least two directions.
4. The tray valve assembly of claim 3 , wherein the at least two directions comprise distinct directions oriented between 0 and 180 degrees relative to the first direction.
5. The tray valve assembly of claim 4 , wherein the at least two directions comprise a direction substantially parallel to the first direction.
6. The tray valve assembly of claim 4 , wherein the at least two directions comprise a direction inducing a turning flow.
7. The tray valve assembly of claim 5 , wherein the at least two directions comprise a direction substantially orthogonal to the first direction.
