“…The property of hardness of the materials was determined before and after making contact with the solution of MEA at 30 % weight (Netzel 2013), in the presence of CO 2 . Samples of the metallic, polymeric, and ceramic materials were assembled on the resin of polymethyl methacrylate (PMMA) in a press Buehler at a temperature of 150°C and a pressure of 28 MPa, to facilitate the manipulation of the samples during the polishing process with sandpaper 240, 320, 400, and 600 grit, to obtain a fine finish.…”

The burning of combustible material that produces emissions released to the atmosphere results in unfavorable climate change due to emissions of CO 2 , NO x , and acid rain by SO x , endangering the health of the population. The treatment of combustion gases by means of a packed absorption column with a high-efficiency liquidgas contactor material reduces pollutant emissions to the atmosphere, where combustion gases make contact with aqueous amine solution of mono ethanol amine (MEA), using different structured packing materials which can be metallic, polymeric, or ceramic. The objective of this work is to study which one of these three types of materials of gas-liquid contactors presents the lowest deterioration in the presence of combustion gases flowing countercurrent to MEA. The materials were evaluated according to the Standard Test Methods ASTM G31-2004 for corrosion testing, ASTM E8-1998 for tension testing, ASTM E384-1990 for microhardness testing, ASTM G5-1999 for potentiodynamic and potentiostatic testing, and the procedure of NRF-194 PEMEX-2007. The properties studied were the tensile strengths, the hardness values, and the elastic moduli, before and after structured packing materials made contact with combustion gases in MEA aqueous solution. The results showed that in acidic and basic mediums, the metallic material was the most resistant to abrasion; it has the highest tensile strength, and presents more resistance during the stress test. The hardness results for the materials were metallic: 190 KH, polymeric: 20 KH, and ceramic: 700KH. The respective corrosion resistances in the presence of MEA were 1.63 9 10 -3 , 3.76 9 10 -3 , and 1.42 9 10 -2 mm/year.
