Abstract
A contacting device and method are presented for the collection, contacting, and distribution of fluids between particulate beds of a downflow vessel, which may operate in co-current flow. By one approach, the contacting device includes a liquid collection tray, a mixing channel in fluid communication with the liquid collection tray, and a liquid distribution zone.
Claims20
A device for fluid contacting in a downflow vessel, comprising:
- a liquid collection tray;
- an enclosed elongate mixing channel;
- a liquid inlet providing fluid communication between the liquid collection tray and the mixing channel;
- and
- a vapor inlet of the mixing channel, downstream of the liquid inlet, for passing vapor into the mixing channel across a fluid stream flowing therethrough.

A device for contacting fluid in a downflow vessel and distributing the fluid therebelow comprising:
- a liquid collection tray;
- an enclosed generally annular mixing channel having an outlet;
- a liquid inlet of the mixing channel having an opening at a bottom portion of the mixing channel for allowing liquid to enter the mixing channel;
- a vapor inlet downstream of the mixing channel and having a vapor inlet opening at a bottom portion of the mixing channel for directing vapor across liquid flowing through the mixing channel;
- and
- a liquid separation and distribution zone in fluid communication with the mixing channel outlet and positioned radially inwardly thereof for distributing fluid from the mixing channel to an inferior stage.
