Thermodynamic Study of binary an ternary systems containing CO2 + impurities in the context of CO2 transportation

Abstract : CO2 capture transportation and storage, or CO2 capture transportation and utilization, are two ways which should be considered in the industry in order to reduce the emission of CO2. After capture, CO2 is not pure and contain impurities like SO2, NOx, N2, O2 and Ar for example. Two binary systems involving CO2 were studied in this work (CO2 + SO2 at 263.15 and ACCEPTED MANUSCRIPT 333.21 K and between 0.1 and 8.8 MPa and CO2 + NO in at 232.93, 252.98 and 273.15 K, and between 1 and 11.5 MPa ) and two ternary systems (CO2 + O2 + Ar and CO2 + SO2 + O2 (expected composition (0.94/0.03/0.03 mole fractions)) at 253, 273 and 293 K, between 1.9 and 7.6 MPa) were also studied experimentally. The equipment used is based on "staticanalytic" method, taking advantage of two capillary samplers (Rolsi™, Armines' patent). The classical Peng-Robinson equation of state is used to represent the isothermal P, x, y data..
