Abstract
An inclined fluid receiving surface (230) is positioned a short distance away from a pipe distributor (210) having a plurality of openings (212) and receives from the openings a liquid-containing fluid (220) with a horizontal momentum (222) in the direction of the pipe flow. The fluid receiving surface (230) further includes a flow-impeding portion (232) that reduces the horizontal momentum (222) of the fluid (220) on the fluid receiving surface (230), thereby significantly improving distribution of the fluid (220).
Claims16
A vessel comprising:
- a pipe distributor at least partially enclosed by the vessel, and wherein the pipe distributor includes a plurality of openings;
- an inclined fluid receiving surface positioned proximal to the pipe distributor, wherein the fluid receiving surface receives a liquid-containing fluid that exits through the plurality of openings;
- wherein the liquid-containing fluid has a horizontal momentum in direction of pipe flow when the fluid impinges on the fluid receiving surface;
- and
- wherein the fluid receiving surface comprises a flow-impeding portion that reduces the horizontal momentum of the fluid on the fluid receiving surface.

A method of improving fluid distribution in a vessel comprising:
- positioning an inclined fluid receiving surface below a pipe distributor, wherein the fluid receiving surface receives a liquid-containing fluid that exits through a plurality of openings in the pipe distributor;
- wherein the liquid-containing fluid has a horizontal momentum in direction of pipe flow when the fluid impinges on the fluid receiving surface;
- and
- including a flow-impeding portion in the fluid receiving surface such that the flow-impeding portion reduces the horizontal momentum of the fluid on the fluid receiving surface.
