| 摘要 |
The object of the invention is a gas-liquid contacting column comprising a gas supply line (2), a liquid supply line (4), at least one functional zone (6) comprising at least one gas-liquid contacting element, functional zone (6) being arranged between gas supply line (2) and liquid supply line (4). Gas supply line (2) cooperates with a distribution zone (8) arranged between the gas supply line and the functional zone, distribution zone (8) consisting of a packing whose height is so selected that the gas coming from the distribution zone circulates with a local velocity over the bed inlet section of the functional zone ranging between -50% and +50% of the average velocity of the gas circulating in the column.
