GAS-LIQUID CONTACTING METHOD AND COLUMN EMPLOYING A COMBINATION OF PLATES AND PACKINGS

摘要

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 The upper tray comprises means 12 for withdrawing liquid from the upper tray, the liquid withdrawn being distributed over the packing.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.
