PVT relationships in a carbon dioxide-rich mixture with ethane

Comprehensive isochoric PVT measurements have been obtained for the system (0.99 CO2 + 0.01 C2H6). The range of state points studied includes those with densities from 2 to 24 mol·dm−3, temperatures from 245 to 400 K, and pressures to 35 MPa. Extensive comparisons have been made with two predictive conformai solution models, one which uses the 32-term BWR-type equation of Stewart and Jacobsen as a reference and the other using the newer Schmidt-Wagner functional form. Results obtained with the Schmidt-Wagner equation are better in the near-critical region owing to the flatter critical isotherm associated with this functional form.
