Crystallization Kinetics of AMP Carbamate in Solutions of AMP in Organic Solvents NMP or TEGDME

Research output: Contribution to journalArticle

Abstract

Novel CO2 capture systems, consisting of 2-amino-2-methyl-1-propanol (AMP), a sterically hindered amine, in the organic solvents N-methyl-2-pyrrolidone (NMP) or triethylene glycol dimethyl ether (TEGDME) have been under investigation as an economical solution to the post combustion carbon capture problem. The carbamate formed during reaction with CO2 may precipitate during absorption and be regenerated with lower energy demands, making it a competitive option. The solubility of the crystals thus formed and the crystallization kinetics of the system need to be better understood as part of understanding the novel systems. A preliminary attempt at such an understanding and estimating crystallization kinetics is therefore, made.
