Gaseous <i>PVTx</i> Properties of the CO₂-N₂O Binary Mixture: Experiment and Simulation.

ABSTRACT: Anthropogenic greenhouse gases are mainly CO₂, CH₄, N₂O, and fluorinated gases. However, due to the toxicity of the CO₂-N₂O mixture, there are few experimental pressure-volume-temperature-composition (PVTx) data available in the literature, which do not meet the temperature-pressure conditions for the applications of carbon capture and storage (CCS). In this work, the gaseous PVTx data of the CO₂-N₂O mixture with molar ratios of 0.6:0.4 and 0.8:0.2 were measured by using a constant-volume vapor phase density apparatus, over a temperature-pressure range of 298.15-473.15 K and 1.0-100.0 bar. The relative standard uncertainty of density ranged from 0.15 to 0.35%. Based on experimental data, a Helmholtz
