A distributor tray () for a column for contact between a gas (G) and a liquid (L) is provided wherein the distributor tray has a plurality of compartments defined on one face of the tray by secant partitions () which are perforated () to allow the flow of liquid between adjacent compartments. Each compartment includes at least one passage of the liquid through the tray or a chimney () projecting from the tray for the exclusive passage of the gas (G) through the tray. The shape of the chimney is identical to the shape of the compartment containing it, and the chimney has an internal volume at least equal to the volume of the compartment containing it.

Distributor tray with compartments and gas risers of the same shape for an offshore gas/liquid contact column

The present invention relates to a gas-redirecting device presenting an upper plane and a plurality of gas-redirecting tubes comprising an inlet end and an outlet end. For each gas-redirecting tube, the orthogonal projections of the inlet end and the outlet end onto the upper plane have an over-lapping area of at most 50% of the total area of the upper plane covered by the orthogonal projections. Also provided is a liquid-gas contacting column comprising a gas-redirecting device, a floating support comprising a liquid-gas contacting column, at least two packed beds and a method for improving the efficiency of a liquid-gas contacting column which is based on redirecting the gas from a wetted zone of a lower packed bed to a wetted zone of the higher packed bed.

Gas redirecting device for liquid-gas contacting column

The invention is a trayfor a column for heat and/or matter exchange between a gas and a liquid, comprising at least one chimneyprojecting from the upper part of trayfor exclusive passage of the gas through the tray, at least one meansenabling passage of the liquid through trayand the inside of at least one of the chimneys providing exclusive gas passage being provided with a material dispersive towards said gas. The invention also relates to an exchange column comprising such a distributor tray and to the use of such a column.

Exchange column distributor tray comprising a dispersive material within a chimney for gas passage

The invention is a distributor tray for at least one a gas/liquid heat and a material exchange column comprising passages for passing gas through the tray. The tray has an upper plate (P) and a lower plate (P) with each plate having at least two distinct liquid passages. The openings (and) of the upper plate (P) are positioned at distinct elevations with at least one of the liquid passages () of upper plate (P) having a lower elevation communicating with one of the liquid passages of the lower plate through a supply line (). The invention also relates to a gas/liquid heat and/or material exchange column equipped with a distributor tray () in accordance with the invention and to a floating barge having a column and to the use of the column.

Compact distributor tray for offshore gas/liquid contact columns

The invention is a distributor tray having at least one perforated wall defining compartments. The distributor tray has at least one distribution compartment through which gas and the liquid flows through the tray, and at least one retention compartment through which the liquid cannot flow through the tray. The at least one retention compartment is on the periphery of the tray. The invention also relates to a column for heat and/or material exchange between a gas and a liquid equipped with a distributor tray, to a floating barge including the column and to the use of the column.

A contactor includes a random packing arrangement in several compartments. The compartments can be delimited by perforated plates or by structured packing walls. A heat and/or material exchange column is equipped with such a contactor. A floating structure includes such a column. A column equipped with such a contactor can be used for a gas treatment, COcapture, distillation or air conversion process.

Exchange column contactor consisting of random packing compartments

A contactor for a heat and/or material exchange column includes an arrangement of two structured packings developing different geometric surface areas and having parallel principal directions. A heat exchange column, a floating structure including such a contactor, and the use of a column equipped with such a contactor are also disclosed.

Exchange column contactor consisting of an arrangement of structured packings

The invention is a distributor tray for a column () for heating and/or material exchange between a gas (G) and a liquid (L). At least one wall () defines compartments () on one of the surfaces of the tray. The walls are perforated () to allow part of the liquid to flow between compartments (). Each compartment has a passage providing flow of the liquid through the tray and for a passage providing flow of the gas through the tray. The invention also relates to a gas/liquid contact column, a gas treatment unit, a COcapture unit, a distillation unit, and an offshore floating barge including the distributor tray. The invention also relates to a method of manufacturing the tray.

Partitioned distributor tray for offshore gas/liquid contact column

The packing includes a pile of plates having corrugations forming a succession of channels comprising fins, each fin being made up of at least one band cut out in one of the plates and remaining secured to the plate on at least one side, the band being deformed so as to create an orifice forming a discontinuity on the surface of the plate, wherein the direction of the channels of a plate forms a non-zero angle with respect to the direction of the edges of an adjacent plate. Finally, the lengths of the fins of a channel are different from those of the fins of a neighboring channel.

High-performance structured packing for a fluid contacting column

The invention is a distributor tray for a column () for heat and/or material exchange between a gas (G) and a liquid (L), comprising at least one means providing passage of the gas through the tray (). The means has at least one chimney (), defining on the surface of the tray () compartments () of substantially identical surface areas. Each compartment comprises at least one means () allowing passage of the liquid through the tray (). The invention also has application to a gas/liquid contact column, a gas treatment unit, a COcapture unit, a distillation unit, an offshore floating barge comprising such a distributor tray and a method of manufacturing the tray.

Distributor tray for offshore gas/liquid contact column

The invention is a method of formation and a structured packing for a fluid exchange column, which defines an exchange surface for at least one descending liquid phase to be placed in intimate contact with at least one ascending gaseous phase. The packing comprises a stack of plates having undulations, each plate being contained in a space included between two parallel planes Land Lseparated by a value of between 5 and 50 mm. The undulations are distributed on both sides of a center plane P separating the space into two equal parts and form a series of channels which extend along a direction D. The channels comprise wings contained in the space included between the two parallel planes. Each wing is composed of a strip B punched out in one of the channels according to at least two grooves Cand C. The width of the strip between the two grooves is between 1 and 15 mm. The strip B is stamped/embossed to create an orifice forming a discontinuity in the surface of the channel at the level of the two grooves Cand C

High performance structured packing for fluid exchange column and fabrication method

A packing structure according to the invention for a fluid contacting column forms a volume comprising an ordered arrangement of bundles of tubes of diameter ranging between 5 and 50 mm. The walls of the tubes comprise orifices which promote circulation and mixes fluids in the structure. The orifices are inscribed in rectangles whose sides range between 2 and 45 mm, and each one of the orifices extends over a surface area greater than 2 mm.
