In the awake of global response for the protection of environment and sustainable development, the removal, disposal and useful utilization of CO2 evolved from different sources is becoming a challenge with time. The coming years should find the carbon dioxide (CO2) use in ever increasing number of applications (e.g. EOR). The major sources of CO2 emission include the burning of fossil fuel, coal fired power plants, oil refining, hydrogen production, several industrial processes and sweetening of natural gas. There is a need of developing new design and solvents for CO2 removal. In this paper physical properties, important in design the acid gas contactor for new potential solvent are experimentally measured. The physical properties such as density (ρ), viscosity (η) and co-efficient of thermal expansion (α) of aqueous solutions of Piperazine (PZ) and (AMP + PZ) were experimentally measured for a wide range of temperature (298.15 to 33.15) K. The mass fractions of PZ were varied from (1.74 to 10.35) wt%. The concentrations for aqueous solutions of (AMP+PZ) were kept higher due to the growing interest in use of concentrated amines in gas processing. The mass fractions of (AMP + PZ) were varied from (28.26/1.74, 26.55/3.45, 23.12/6.88 to 19.65/10.35) %. All the properties were correlated as a function of temperature. The measured and correlated values are found to be in good agreement. All measured physical properties have shown the decreasing effect while increasing the temperature
