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 method for fluid contacting in a downflow vessel, the method comprising:
- collecting liquid on a liquid collection tray;
- passing at least a portion of the liquid through an inlet of an enclosed mixing channel of a mixing device and downstream through the mixing channel;
- and
- passing at least a portion of vapor through a vapor inlet of the mixing channel downstream of the liquid inlet and across the liquid stream flowing through the mixing channel to contact the vapor and liquid in the mixing channel.

A method for fluid contacting in a downflow vessel, the method comprising:
- passing vapor and liquid from a superior stage of a downflow vessel to a mixing stage of the downflow vessel;
- collecting liquid on a liquid collection tray;
- passing at least a portion of the liquid through an inlet of an enclosed mixing channel and downstream through the mixing channel;
- passing at least a portion of the vapor through a vapor inlet of the mixing channel downstream of the liquid inlet and across the liquid stream flowing through the mixing channel to mix the vapor and liquid in the mixing channel;
- and
- distributing the vapor and liquid to an inferior stage of the downflow vessel below the mixing stage.
