The purpose of this chapter is to discuss some structural characteristics and
properties of three regular packing materials: metallic, polymeric and ceramic; in order
to select the best one to capture CO2 in an absorption column. The study was conducted
by making the following tests: geometric physical properties such as wetted area and
porosity; mechanical properties like, stress, hardness, modulus and compression
resistance, structure and microstructure morphologic, chemical composition, rate of
corrosion in electrochemical cell in medium of 1N of H2SO4 and Monoethanolamine
(MEA) at 30% in aqueous solution by using standard procedures of the American
Society of Testing Materials (ASTM) and own developed procedures for the equipment
used. The structures of materials were also evaluated by X-ray diffraction and the
surface of the material by scanning electron microscopy. It was concluded that metallic
material is suitable for CO2 gas treatment because it was presented with the lower
etching 1N of H2SO42.
