The present study introduces a generalized correlation for the interaction coefficients of N2(i)/hydrocarbon(j) binary systems as a function of the reduced temperature of nitrogen (T(ri)) and the acentric factor of the hydrocarbon (omega(j)). It is applicable to the translated-modified Peng-Robinson equation of state (t-mPR EoS) and the original PR as well. The prediction results for N2/n-alkane binary systems are satisfactory with an average absolute error in bubble-point pressure below 6%. Equally good results are obtained for the binaries of N2 with naphthenes, iso-alkanes and aromatics. Use of temperature independent interaction coefficients is recommended for the N2/alkene systems. The proposed correlation is limited to pressures lower than 500 bar, and gives better prediction than those reported previously. (EN)
