Aqueous Piperazine/N-(2-Aminoethyl) Piperazine for CO2 Capture
Energy Procedia, 2013 AbstractA novel blend of piperazine (PZ) with N-(2-aminoethyl) piperazine (AEP) has been proposed as a superior solvent for CO2 capture from coal-fired flue gas. Blending PZ with AEP can remediate the precipitation issue of concentrated PZ while maintaining its high CO2 absorption rate, and high resistance to degradation.

The kinetics of carbon dioxide capture by solutions of piperazine and N-methyl piperazine
International Journal of Global Warming, 2011 In this paper, kinetics and mechanism of the reaction between CO 2 and piperazine (PZ) or n-methyl piperazine (NMP) in aqueous and alcoholic solutions were investigated using direct stopped-flow technique under a range of temperatures (278, 288 and 298 K).
