    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.

    Abstract: The present invention relates to a liquid-gas contacting unit (1) comprising a column (100), at least a lower packed bed (110) and a higher packed bed (120) positioned higher than the lower packed bed (110) inside the column (100), a gas-tight liquid collecting and redistributing device (130) disposed between the lower and the higher packed bed (110; 120) inside the column (100) and an external pipe (140) outside the column (100), the external pipe (140) comprising an inlet end (141), an outlet end (142) and a peripheral wall (143) between the inlet end (141) and the outlet end (142); the inlet end (141) being positioned between the lower packed bed (110) and the gas-tight liquid collecting and redistributing device (130) and the outlet end (142) being positioned between the higher packed bed (120) and the gas-tight liquid collecting and redistributing device (130). The present invention also relates to a method for improving the efficiency of a liquid-gas contacting unit by directing the gas from the lower packed bed to the higher packed bed through the external pipe.
