<p>A column structure (21) 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 (21) comprises at least one vessel having an elongate upright wall structure (15) to define an absorption process volume for the containment of high surface area packing and for the countercurrent flow of absorbent liquid reagent and target gas in use; and a column perimeter structure (22) comprising an elongate upright wall structure disposed around the at least one vessel in such manner that an inner wall of the elongate upright wall structure and an outer wall of a vessel cooperably define and fluidly enclose at least one secondary fluid volume fluidly isolated from the absorption process volume (s). 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> |
