Characterization of Alkanolamine Blends for Carbon Dioxide Absorption. Corrosion and Regeneration Studies

There are a lot of research programs focusing on the development of new solvents for carbon dioxide capture. The most important priority should be reducing the energy consumption needed at the regeneration step, but minimizing solvent degradation and its corrosivity is also considered as a priority. In this research, the aqueous blends of 2-amino-2-methyl-1-propanol (AMP: 1 kmol center dot m(-3)) and 1-amino-2-propanol (MIPA: 0.1-0.5 kmol center dot m(-3)) are characterized in terms of density, viscosity, and surface tension. The carbon dioxide absorption rate and capacity, the regeneration capacity, and the corrosivity of these solvents are also evaluated.

Automated summary

Research is focused on developing new solvents for carbon dioxide capture, with a primary goal of reducing energy consumption and minimizing solvent degradation and corrosivity. This study evaluates aqueous blends of AMP and MIPA in terms of physical properties and performance in CO2 absorption, regeneration, and corrosivity.
