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 present invention relates to a liquid-gas contacting unit comprising a column, at least a lower packed bed and a higher packed bed positioned higher than the lower packed bed inside the column, a gas-tight liquid collecting and redistributing device disposed between the lower and the higher packed bed inside the column and an external pipe outside the column, the external pipe comprising an inlet end, an outlet end and a peripheral wall between the inlet end and the outlet end; the inlet end being positioned between the lower pack bed and the gas-tight liquid collecting and redistributing device and the outlet end being positioned between the higher pack bed and the gas-tight liquid collecting and redistributing device. The present invention also relates to a method for improving the efficiency of a liquid-gas contacting unit.

Abstract: The present invention relates to a column (CO) for the exchange of material and, if appropriate, heat between a gas and a liquid. The exchange column (CO) comprises at least one collector tray and a system for distributing liquid arranged between two packing beds (7), and means for recirculating the liquid (8). The means for recirculating the liquid (8) connect a zone situated below the packing bed (7) to a zone situated above the distributor tray.

Abstract: The present invention is directed to a process for the removal of aromatic hydrocarbons from a lean acid gas containing less than 20 mol. % of H2S, comprising:a) contacting the lean acid gas stream (1) with a H2S-selective liquid absorbent solution (29) in a first absorption zone (2) to produce a gas stream depleted in H2S (3) and an absorbent solution enriched in H2S (4),b) introducing the absorbent solution (4) into a non-thermic stripping zone (8) where it is contacted with a stripping gas stream (7) to obtain an absorbent solution depleted in C4+ aliphatic and aromatic hydrocarbons (9) and a stripping gas stream enriched in aromatic and C4+ aliphatic hydrocarbons (10),c) contacting the stripping gas stream (10) obtained in step b) with a H2S-selective liquid absorbent solution (28) in a second absorption zone (12) to obtain a stripping gas stream depleted in H2S (13), and an absorbent solution enriched in H2S (14)d) introducing the absorbent solution (9) obtained in step b) into a desorption zone (16) wherein the H2S-selective liquid absorbent solution (17) is recovered and a lean acid gas is produced.
