摘要：
A thermodynamic and economic comparison of post-combustion CO(2) capture processes using aqueous solutions of piperazine (PZ) promoted potassium carbonate (K(2)CO(3)) and monoethanolamine (MEA) based on fair boundary conditions and constant assumptions using rigorous thermodynamic models is described. In contrast to a first preliminary comparison, it is shown that under the stated assumptions and considered boundary conditions, a 7 m MEA solution performs better in both thermodynamic and economic terms than aqueous solutions of K(2)CO(3) and PZ.
