On the phase behaviour of the CO2 + N2O4 system at low temperatures

Carbon dioxide capture transportation and storage is one of the technologies that can be employed to reduce CO2 emissions from power plants. Unfortunately, in post combustion process, not pure contains impurities like SO2, NOx, N2, O2 Ar for example. In this paper, Vapour-Liquid-Equilibrium (VLE) a binary system composed N2O4/NO2 have been investigated. The equipment used based on “static-synthetic” method with variable cell determine bubble pressure or saturated system. setup was obtain point data at four isotherms (253.43, 273.43, 293.43, 303.43) K pressures up 7.3 MPa. accuracies measured temperature were estimated 0.03 0.12 kPa, respectively. Peng–Robinson equation state (PR78 EoS) represent isothermal P, x data.
