Abstract

Global warming is a major issue that needs to be addressed and limited. The CESAR1 solvent blend has a high potential for becoming a commonly employed, commercial solvent system. In this work, the viscosity and density data for aqueous CO2 loaded CESAR1 (26.6 wt.% AMP 12.8 wt.% PZ) solution are measured over the temperature range 293 to 353 K and for CO2 loading going from 0 to 0.59 mol of CO2 per mole of amine. Additionally, soft model correlations are proposed, and experimental challenges are highlighted.

Keywords: Amine-based Chemical Absorption, CESAR1 solvent, Viscosity, Density.
