The crossover method can be used in the classical equations of state (EOSs) to study the singular behavior of fluids in the critical region. However, this usually involves introducing additional system-dependent parameters and changing the values of classical parameters in the EOS with curve fits that require large amounts of experimental data. This work presents a crossover volume translation Soave-Redlich-Kwong (SRIC) equation of state with unchanged classical parameters and crossover parameters either set as constants or determined solely by the critical compressibility factor. This EOS is used to describe the VLE and p rho T data of 16 fluids (n-alkanes from methane to hexane, Ar, N-2, O-2, CO2, CO, H2S, SO2, R22, R125, and R245fa) to show that the crossover volume translation SRK EOS can accurately predict experimental data both far from and near the critical point.
