MDEA/Piperazine as a solvent for CO2 capture
- Fred Closmann, Thu Nguyen, G. Rochelle
- Chemistry
- 1 February 2009
Abstract The solvent blend methyldiethanolamine/piperazine (MDEA/PZ) has been investigated as an alternative for CO2 capture from coal-fired power plants. MDEA/PZ offers advantages over… Expand
Accurate screening of amines by the Wetted Wall Column
- X. Chen, Fred Closmann, G. Rochelle
- Chemistry
- 2011
Abstract To screen amine solvents accurately for CO 2 capture, a Wetted Wall Column (WWC) was used to measure equilibrium CO 2 partial pressure and CO 2 absorption/desorption rate at variable CO 2… Expand
Degradation of aqueous methyldiethanolamine by temperature and oxygen cycling
- Fred Closmann, G. Rochelle
- Chemistry
- 2011
Abstract The primary degradation products identified in aqueous 7 molal (m) methyldiethanolamine (MDEA) loaded to 0.1 mol CO 2 /mol alkalinity and degraded in the Integrated Solvent Degradation… Expand

Oxidative Degradation of Amines With High-Temperature Cycling☆
- A. Voice, Fred Closmann, G. Rochelle
- Chemistry
- 2013
Abstract Amines were oxidatively degraded in various cycling systems that closely resembled a real CO2 capture plant. 2- amino-2-methyl-propanol (AMP) showed the best resistance to oxidation.… Expand
