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] In particular reference is made to the following detailed description of the tray according to the invention Figure 7 to Figure 9 , Figure 7 to Figure 9 Various non-limiting embodiments are illustrated.

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

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

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

Abstract

The invention relates to a distributor tray (100) for a column intended for contact between a gas (G) and a liquid (L), the distributor tray comprising a secant partition (104) A plurality of compartments are defined on the face of the tray, the partitions being perforated (105) to allow liquid flow between adjacent compartments. Each compartment comprises at least one means for passing liquid through the tray or comprises a gas riser (102) protruding from the tray to pass said gas (G) exclusively through the tray. The shape of the chimney is the same as that of the compartment containing it, and the internal volume of the chimney is at least equal to the volume of the compartment containing it.

Description

technical field [0001] The present invention relates to the field of trays for gas / liquid contacting columns, and more particularly to the field of trays used in gas treatment, CO 2 Offshore columns used in units for capture, gas dehydration or distillation. Background technique [0002] For gas treatment or CO with amine scrubbing 2 Captured offshore units include columns for 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, such as are known as FPSOs ("Floating Production, Storage and Offloading"). and offloading) or FLNG ("Floating Liquefied Natural Gas", floating liquefied natural gas) type ships, floating barges or offshore platforms. Distillation columns or gas dehydration columns are also installed on floating barges. [0003] In this description, these columns for the exchange of ...
