Abstract

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