Column structure for an absorption column

摘要

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.

1. A method of assembly of a column structure for containment of packing material and absorbent liquid reagent for removal of a target gas from a gas stream comprising:
providing at least one vessel module each comprising a plurality of sub-modules configured to be assembled together and having an elongate upright structure, and providing a column top support structure; assembling multiple such pluralities of sub-modules together in elongate array to form multiple elongated vessel modules; arranging the vessel modules together alongside one another to constitute collectively said column structure such that the vessel modules collectively comprise a columnar vessel assembly; supporting each vessel module mechanically in a vicinity of an upper part of the column structure so assembled via the top support structure, wherein each vessel module is assembled by assembly of each of its plurality of constituent sub-modules successively from a top downwards.
