Corrosion rate study of aqueous 2-amino-2-hydroxymethyl-1,3- propanediol (AHPD) and its mixture with piperazine (PZ)

Carbon dioxide emission has been a worldwide concern around the globe due its greenhouse effect that leads to global warming. Current amine treating plant is used to remove C02 by absorption process using alkanolamines as an absorbent. Recently sterically hindered amines such as AHPD many others...

Current amine treating plant is used to remove C02 by absorption process using alkanolamines as an absorbent. Recently sterically hindered amines such as AHPD many others have grown interest in C02 absorption area due to its high C02 solubility (up to 1 mol C02/mol AHPD). Piperazine is a chemical derivative added to AHPD to enhance its absorption capacity to even more than 1 mol C02/mol AHPD. However, all amine solutions whether it is lean or saturated with C02 is corrosive. This has caused all plants that operate C02 absorption using amine solution encounter severe corrosion problems.

This present study provides information on the corrosion rate of AHPD at different concentrations and also the effect of mixing ratio of AHPD/PZ blends. An electrochemical testing of Linear Polarization Method is used to evaluate the corrosion rate. The corrosion rate of AHPD solution is found to be increasing with increasing concentration of AHPD. For AHPD/PZ blends, it is found that when amount of PZ added to AHPD is increased, the rate of corrosion decreases which shows that PZ acts as a corrosion inhibitor when mixed with AHPD.
