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 35):
The method of  claim 34  wherein at least two of the at least four mass transfer decks on each of the multiple pass, parallel flow downcomer tray are configured to discharge the descending liquid into the opening of the peripheral downcomers and at least two of the at least four mass transfer decks are configured to discharge the descending liquid into the central downcomers; and\n wherein the liquid flow traversing each of the at least four mass transfer decks on each of the plurality of the multiple pass, parallel flow downcomer trays is in a direction opposite to the liquid flow traversing the at least two adjacent mass transfer decks.
