Abstract:
A multiple pass, parallel flow downcomer tray for a mass transfer column and method for liquid-vapor contacting in a mass transfer column is provided. The multiple pass, parallel flow downcomer tray has at least four mass transfer decks configured to provide contact between an ascending vapor passing upward through apertures on the tray surface and a traversing liquid on the tray surface. The tray further includes a central downcomers disposed near a central axis of the tray and two or more peripheral downcomers disposed near the edge of the tray and spaced apart from the central axis, wherein at least two of the four mass transfer decks are configured to discharge the traversing liquid into the peripheral downcomers and two of the four mass transfer decks are configured to discharge the traversing liquid into the central downcomer.

Claim (Index 33):
A method for liquid-vapor contacting in a mass transfer column, the method comprising the steps of:\n (a) directing a descending liquid to a plurality of multiple pass, parallel flow downcomer trays arranged in a stacked orientation within the mass transfer column, each multiple pass, parallel flow downcomer tray comprising: (i) a tray surface defining a plurality of liquid receiving pans, and at least four mass transfer decks having a plurality of apertures, wherein each mass transfer deck being disposed adjacent to at least two other mass transfer decks; and (ii) a plurality of downcomers configured for collecting and discharging the descending liquid, the plurality of downcomers each having an opening at a collection location for collecting the descending liquid from one or more of the mass transfer decks, a ramp-like channel for discharging the collected descending liquid to one of the plurality of liquid receiving pans on another of the plurality of multiple pass, parallel flow downcomer trays, wherein the collected descending liquid is discharged from each downcomer at a discharge location below the tray surface that is not vertically aligned with the collection location of the opening of the downcomer; (b) directing an ascending vapor through the mass transfer column to the plurality of multiple pass, parallel flow downcomer trays and through the plurality of apertures on the mass transfer decks; (c) contacting the ascending vapor passing through the apertures and the descending liquid on the mass transfer decks of each of the plurality of multiple pass, parallel flow downcomer trays; wherein there are multiple liquid flows on the mass transfer decks of each of the plurality of multiple pass, parallel flow downcomer trays and the liquid flows are in a parallel type flow path in vertically successive mass transfer decks of adjacent multiple pass, parallel flow downcomer trays to achieve a Lewis Case  2  type flow arrangement through the mass transfer column.
