Abstract
The invention relates to a column comprising a jacket that bounds at least a first jacket space (M) and a second jacket space arranged thereabove along the longitudinal axis (L). The e first jacket space is separated from the second jacket space by a gas-permeable first chimney tray. A gaseous phase flows upward into the first jacket space, through the first chimney tray into the second jacket space, and then flows upward into the second jacket space. In the first jacket space the gaseous phase (M), in counter-current flow, contacts a first liquid washing agent, and in the second jacket space the gaseous phase, in counter-current flow, contacts a second liquid washing agent. The first chimney tray has a separator for separating the second washing agent, which separates the second washing agent (W') and directs it into the second jacket space. The invention further relates to an apparatus comprising the column and a method for separating COfrom a gaseous phase.
