Problems solved by technology

If the cylindrical risers are installed in the compartment without contact with the wall 54, they will block a large amount of liquid through the hole 51, to the detriment of the quality of liquid distribution
These design and production issues are exacerbated for trays with large diameters (for example, 4 or 5 meter diameter trays)

Embodiment Construction

[0054] The following detailed description of the tray according to the invention refers in particular to Figure 7 to Figure 9 , Figure 7 to Figure 9 Various non-limiting embodiments are illustrated.

[0055] Figure 7 In particular a part of a tray according to an embodiment of the invention is illustrated in a schematic manner.

[0056] The tray 100 according to the invention is a gas distributor tray for a column for heat and / or mass exchange between gas G and liquid L. The tray according to the invention has a gas distribution function and a liquid distribution function. In this sense, in the remainder of the description reference will be made to "distributor" trays to denote trays which perform both the liquid and gas distribution functions.

[0057] Distributor tray 100 includes two sides, an upper side and a lower side. The side of the tray 100 which is oriented towards the top of the exchange column is referred to as the upper side of the tray 100 . In contrast,...

Abstract

The invention relates to a distributor tray (100) for a contact column for contact between a gas (G) and a liquid (L), comprising a plurality of compartments defined on a surface of the tray by perforated (105) secant partitions (104) to allow the flow of liquid between adjacent compartments. Each compartment comprises at least one means for the passage of the liquid through the tray, or a riser (102) projecting from the tray for the exclusive passage of said gas (G) through the tray. The shape of the riser is identical to the shape of the compartment which contains said riser, and the riser has an internal volume at least equal to the volume of the compartment which contains said riser.

Description

technical field [0001] The present invention relates to the field of trays for gas / liquid contact columns, and more particularly to the field of trays used especially in gas processing, CO 2 Offshore towers used in units for capture, gas dehydration or distillation. Background technique [0002] For gas treatment by amine scrubbing or CO 2 Captured offshore units include towers for the absorption and regeneration of fluids, which may be liquid or gaseous. These absorption and regeneration towers operate with countercurrent or cocurrent gas / liquid flow and are installed on ships, floating barges or offshore platforms, for example known as FPSO ("Floating Production, Storage and Offloading", floating production, storage and unloading) or FLNG ("Floating Liquefied Natural Gas", floating liquefied natural gas) type ships, floating barges or offshore platforms. Distillation towers or gas dehydration towers are also installed on floating barges. [0003] In the present descrip...
