Abstract

© 2020 by the authors. Amine based CO2 capture is considered as one of the most effective technologies for mitigating global warming and climate change problems. The key of this technology is to use as highly effective solvent. In the present work, novel formulated MPDL-AMP solvent has been firstly introduced. Its essential data for determining and investigating the solvent performance as an alternative solvent for capturing CO2 has not yet been reported. Therefore, density, viscosity, and physical CO2 diffusivity of novel formulated MPDL-AMP solvent were determined in this work over ranges of concentrations and temperatures of 25%wt. MPDL/5%wt. AMP to 15%wt. MPDL/15%wt. AMP and 313 K to 333 K, respectively. The physical data reported in the present work are important for determining the optimum hydrodynamics of the fluid flow inside the absorption column as well as designing the height of the column through the kinetics and the mass transfer data. The results observed in the present work showed that the novel formulated MPDL-AMP solvent should be further investigated for its potential to be used as an alternative solvent for capturing CO2.
