Abstract

Air contains impurities, which must be removed before its transformation and utilization. In the present work, new isothermal vapor-liquid equilibrium (VLE) data are reported for three binary systems containing NO with (CO, N2, or Ar) at different temperatures (between 105 and 146 K) and pressures up to 4 MPa. The compositions of the coexisting phases were experimentally determined using an apparatus based on the "static-analytic" method. The Peng-Robinson equation of state combined with different mixing rules (classical, Wong-Sandler, and Huron-Vidal) were used to represent the phase diagram (P, x, y).
