Solubility of CO2 in aqueous solutions of DAMP+MDEA, DAMP+MEA, DAH+MDEA and DAH+MEA

摘要: Abstract The main goal of this research is to investigate absorption rate and capacity carbon dioxide in aqueous mixtures DAMP(1,5-Diamino-2-methylpentane)+MDEA(Methyl-diethanolamine), DAMP+MEA(Monoethanolamine), DAH(1,6-Diaminohexane)+MDEA DAH+MEA an isothermal stirred batch reactor. experiments are designed temperature ranging from 30 50 °C, at low pressure various molar ratios. results show that although there interaction between diamine conventional amines concentration, after a minimum point, increasing DAMP DAH concentration increases solutions all temperatures. Then, equation developed predict solution based on Zwitterion mechanism. kinetic constant order reaction determined considering the absolute difference measured predicted as objective function. first with respect amine third overall.
