“…Despite the use of 13 coefficients, the equation from [12] described the experimental data in [13] for an N 2 -O 2 mixture (110 points in the range of 75-125 K) with a root mean square deviation of 2.42% for pressure. In an exact approximation, the relative deviation would be less than this value, since the pressure of this mixture at 75 K was 4-6 times higher than ours at 65 K.…”

Three forms of equations for describing experimental data on liquid and vapor pressures, depend ing on temperature and composition at phase equilibria in binary mixtures, are proposed and evaluated. It is determined that the form of equation depends on the relationship between the temperature of a mixture and the critical temperatures of the components of the mixture. Exact data on the phase equilibria in nitrogenoxygen, nitrogen-argon, and oxygen-argon mixtures [1] are approximated to assess the effectiveness of the equations' forms. It is found that the equations also allow us to determine the phase composition at a given temperature and pressure and temperatures of phases at a given pressure and composition.

Vapor-liquid equilibria for binary and asymetric systems include carbon dioxide+C 1 -C 8 , C 10 are calculated by using the Peng-Robinson-Stryjek-Vera equation of state coupled with the modified MHV2 mixing rule. The modified UNIFAC model is used for determining activity coefficient and excess Gibbs free energy. Calculated equilibrium pressures and mole fractions in vapor phase are compared with the experimental data. The average absolute deviation percent (AAD%)s indicates that the error involved in the application of the MHV2 mixing rule by optimized q 1 and q 2 is less than WS and PRSK mixing rules in most cases.
