<p>A column structure is described for the containment of high surface area packing and absorbent liquid reagent for the removal of a target gas from a gas stream. The column structure comprises a plurality of vessel column modules each having an elongate upright wall structure, each column module comprises a plurality of vertically disposed sub-modules, the modules being disposed together alongside one another in two dimensional array to constitute collectively the column structure. A column top support structure is located in the vicinity of the upper part of a column structure so assembled and each column module is mechanically supported from the column top support structure. A method of assembly of such a column and to a method of removal of a target gas from a gas phase using such a column are also described.</p> |
