Abstract: The gas-liquid contact column comprises at least an upper tray 10 and a lower tray 10, as well as a downcomer 2 for sending the liquid from the upper tray to the lower tray. The trays comprise gas ports. A packing 11 is arranged between the upper tray and the lower tray. The upper tray comprises means 12 for withdrawing liquid from the upper tray, the liquid withdrawn being distributed over the packing.The gas-liquid contact column is particularly well suited for absorption of the CO2 and of the H2S contained in a natural gas or in a syngas, and for capture of the CO2 contained in combustion fumes.

Abstract: The gaseous effluent to be treated is contacted in C1 with an absorbent solution selected for its property of forming two separable phases when it has absorbed an amount of acid compounds and when it is heated. The absorbent solution laden with acid compounds is then heated in E1 and E3 so as to separate two fractions in BS1: a first absorbent solution fraction depleted in acid compounds and a second absorbent solution fraction enriched in acid compounds. The second fraction is regenerated in C2 so as to release part of the acid compounds, and the first absorbent solution fraction and the regenerated absorbent solution are recycled as absorbent solution.According to the invention, an absorbent solution portion circulating in C1 is cooled in E2 in order to prevent demixing of the solution in column C1.

Abstract: A gas-liquid contact column tray has a section including a gas pathway (SAA) and a liquid pathway section (SD) delimited by at least one downspout, wherein a deflecting system including a roof is included, located above the liquid gas interface at the level of the liquid pathway section (SD), in order to apportion the gas phase over a surface section greater than the section including the means of gas pathway (SAA). In a method for gas-liquid contact in such a column, most of the gas phase part is redirected and apportioned over the whole pathway section available for gas, corresponding to the tray section provided with the gas pathway (SAA), increased by the liquid pathway section (SD), using a deflecting system consisting of the roof located higher than the gas-liquid interface level of the liquid pathway section (SD), and the liquid collected is evacuated toward the lower tray.
