摘要： The present invention relates to a column for exchange of mass, and where appropriate heat, between a gas and a liquid. The column comprises at least one collection tray and a liquid distribution system (5, 6) arranged between two packed beds (7), and gas and liquid separation means (8). The present invention proposes to arrange gas and liquid separation means (8) between the collection tray (4) and the liquid distribution means (5, 6).

摘要： 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.

摘要： 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.

摘要： 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.
