Abstract

A construction element for a plant for capture of an acidic gas using an aqueous amine absorbent, wherein at least a part of a surface of said element comprises a polyolefin, and a hydrolytically stable antioxidant, is described. Additionally, a liner comprising said polyolefin and the hydrolytically stable antioxidant, is described. The construction element may be a column, a pipe, an insert, like a column packing element or a tray. An apparatus for capturing CO2 using the construction elements, is also described.
