Densities of Carbon Dioxide + Nitrogen from 225 K to 450 K at Pressures up to 70 MPa

This paper reports PVT measurements for five gravimetrically prepared mixtures of CO2 + N2 from 225 K to 450 K at pressures up to 70 MPa. These results have been determined using a continuously-weighed pycnometer. A detailed error analysis indicates that the accuracy of the densities is better than...

Description
Summary:This paper reports PVT measurements for five gravimetrically prepared mixtures of CO2 + N2 from 225 K to 450 K at pressures up to 70 MPa. These results have been determined using a continuously-weighed pycnometer. A detailed error analysis indicates that the accuracy of the densities is better than ±0.1%. Additional PVT data for CO2 + N2 mixtures have been measured by Netherlandse Gasunie, Ruhrgas, and Gaz de France as reported by Jaeschke and Humphreys (1990).
