Corrosion ratestudy of mildsteel in Aqueous 2-smino-2-ctbyl-1 ^-propanediol (AEPD)

As there is growing concern that carbon dioxide (C02) emissions are contributing to
global climate change, it is critical to develop technologies to mitigate this problem. One
very promising approach in reducing CO2emissions is CO2capture at a power plant,
transport to an injection site, and sequestration for long-term storage in any ofa variety
of suitable geologic formations. Most common amine solutions used in absorbing CO2
are the alkanolamines such as MEA, DEA and MDEA. Meanwhile, application of
sterically hindered amines (SHA) such as AHPD, AEPD, and AMP in gas treating
technology are also being studied, as to compare with alkanolamines, in terms ofthe
feasibility ofbeing applied for future application in CO2absorption approach. After all,
all amine solutions whether it is lean or saturated with CO2 are corrosive. Due to the
effect, all plants that operate CO2absorption have to counter the case ofcorrosion
effectively with the improved method, day by day. With this in mind, it is here to present
as a research to minimize corrosion by taking into account ofthe emerging sterically
hindered amines(SHA), as the chosen SHA is 2- amino-2-ethyl-l,3-propanediol
(AEPD), due to the high uptake on CO2absorption , and stable form of carbamate
formed during the reaction with CO2.
