Abstract

The climate change issues due to the emissions of carbon dioxide from various sources have become a challenge for many years because of the various negative effects on social, economic and environmental aspects. The most commonly applied technique is absorption by chemical solvents. Piperazine, in particular, has been used in the past as activator when mixed to other amines, such as methyldiethanolamine. Nowadays in literature also aqueous solutions containing pure piperazine are considered for CO2 capture. In this work properties such as density, viscosity and diffusivity of carbon dioxide related to this solvent have been carefully studied, taking into account the influence of carbon dioxide. New correlations have been proposed in order to best reproduce experimental data.
