Abstract: The present invention relates to a gas-redirecting device (100) presenting an upper plane and a plurality of gas-redirecting tubes (3) 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. The present invention also relates to a liquid-gas contacting column (201) comprising such a gas-redirecting device (100), a floating support comprising such a liquid-gas contacting column, at least two packed beds (210, 220) 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, the liquid load through the wetted zone of the lower packed bed is different from the liquid load through the wetted zone of the higher packed bed.

Abstract: The present invention relates to a column for heat and/or mass exchange between a gas and a liquid. The column comprises at least one collection tray (1), at least one packed bed, and means for mixing a gas flow (7, 8). According to the invention, the means for mixing a gas flow are positioned underneath the collection tray (1) and above the packing.

Abstract: The invention relates to a high-performance structured packing for a fluid contacting column. The packing is formed by a stack of plates comprising corrugations forming a succession of channels. The channels include wings and each wing is formed by at least one band cut into one of the plates so that it remains solidly connected to the plate on at least one side, said band being deformed to create a hole that breaks the continuity of the surface of the plate. According to the invention, the direction of the channels of one plate forms a non-zero angle in relation to the direction of the ridges of an adjacent plate. The lengths of the wings of one channel are different from those of a neighbouring channel.

Abstract: The invention relates to a column for bringing a gas and a liquid into contact, comprising a gas supply conduit (2), a liquid supply conduit (4), at least one functional zone (6) comprising at least one element for bringing a gas and a liquid into contact, the functional zone (6) being arranged between the gas supply conduit (2) and the liquid supply conduit (4). The gas supply conduit (2) co-operates with a distribution zone (8) arranged between the gas supply conduit and the functional zone, the distribution zone (8) consisting of a lining, the height of which is selected in such a way that the gas emitted from the distribution zone circulates according to a local speed at the bed inlet section of the functional zone, that is between -50 % and +50 % of the average speed of the gas circulating in the column.
