  • Chemical Absorption Kinetics in MEA Solution with Nano-particles

    Jiang, Jiazong   Zhao, Bo   Cao, Meng   Wang, Shujuan   Zhuo, Yuqun  

    Recently, carbon dioxide (CO2) capture and storage (CCS) technology has been a hot research topic since CO2 emissions are one of the most important reasons of global warming and climate change. In this study, CO2 absorption system was established to study the chemical absorption process of CO2 in MEA solution with nano-particles. This paper mainly aims to study the mass transfer enhancement with the presence of nano-particles in the CO2 absorption process. The nano-fluids used in this work were prepared by the ultrasonic treatment without any surfactants. It was found that the CO2 absorption rate could be enhanced by up to 8% with the presence of nano-particles compared to the pure MEA solution.

  • Experimental study of CO2 absorption in aqueous MEA and MDEA solutions enhanced by nanoparticles

    Jiang, Jiazong   Zhao, Bo   Zhuo, Yuqun   Wang, Shujuan  

    The nanofluids based on MEA and MDEA solutions were prepared using ultrasonic dispersion method without any surfactant addition to study the influence of nanoparticles on the CO2 absorption by MEA and MDEA in the bubbling reactor. The influences of various factors including solid loading of nanoparticles, nanoparticle size, nanoparticle type, total volume flow rate of mixed gas and initial CO2 volume fraction on the CO2 absorption were investigated. Although the reaction rates of MBA-CO2 and MDEA-CO2 were different, the findings about the influence of nanoparticles based on MDEA solution were similar to that based on MEA solution. Most of tested nanoparticles could remarkably improve the gas-liquid mass transfer during the CO2 absorption process. The CO2 absorption enhancement factor increased with the increase of the solid loading of nanoparticles up to a maximum value and then decreased. The CO2 absorption enhancement factor based on the MEA solution for larger nanoparticles was greater than that for smaller nanoparticles. On the other hand, the absorption enhancement effect of nanoparticles based on the MDEA solution depends highly on the type of nanoparticle. It is also found that the enhancement factor based on the MDEA solution increased with the increase of the total volume flow rate of mixed gas or the initial CO2 volume fraction.
