Abstract:
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.
Abstract:
The invention relates to a tray 2 for a column intended for heat and/or matter exchange between a gas and a liquid, comprising at least one chimney 4 projecting from the upper part of tray 2 for exclusive passage of the gas through the tray and at least one means 5 enabling passage of the liquid through tray 2, the inside of at least one of the chimneys for 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.
Abstract:
The packing consists of a pile of plates comprising 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 neighbouring channel.

The invention is a tray 2 for a column for heat and/or matter exchange between a gas and a liquid, comprising at least one chimney 4 projecting from the upper part of tray 2 for exclusive passage of the gas through the tray, at least one means 5 enabling passage of the liquid through tray 2 and 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.
Abstract:
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.
Abstract:
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, CO2 capture, distillation or air conversion process.
Abstract:
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.
Abstract:
The invention relates to a contactor (3) comprising a random packing arrangement (A) in several compartments. The compartments can be delimited by perforated plates (P) or by structured packing walls.The invention also relates to a heat exchange column, to a floating structure and to the use of a column equipped with such a contactor.
Abstract:
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 (P1) and a lower plate (P2) with each plate having at least two distinct liquid passages. The openings (10 and 11) of the upper plate (P1) are positioned at distinct elevations with at least one of the liquid passages (10) of upper plate (P1) having a lower elevation communicating with one of the liquid passages of the lower plate through a supply line (9). The invention also relates to a gas/liquid heat and/or material exchange column equipped with a distributor tray (2) in accordance with the invention and to a floating barge having a column and to the use of the column.
Abstract:
The invention is a distributor tray for a column (1) 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 (2). The means has at least one chimney (4), defining on the surface of the tray (2) compartments (8) of substantially identical surface areas. Each compartment comprises at least one means (5) allowing passage of the liquid through the tray (2). The invention also has application to a gas/liquid contact column, a gas treatment unit, a CO2 capture unit, a distillation unit, an offshore floating barge comprising such a distributor tray and a method of manufacturing the tray.
