Abstract

Several properties important for the absorption of carbon dioxide and nitrous oxide in solutions of diethanolamine (DEA) or di-2-propanolamine (DIPA) and polyethylene glycol (PEG 400, average molecular weight 400) were determined experimentally. These properties include the density and viscosity of the amine-PEG 400 solutions, the physical solubility and diffusivity of CO2 in PEG 400, and the physical solubility and diffusivity of N2O in DEA-PEG 400 and DIPA-PEG 400 solutions. The results were obtained for 0–30 wt % amine in PEG 400 over the temperature range of 20–40 °C. The results were correlated for temperature and composition dependence.
