郑大庆. MODIFIED SRK EQUATION OF STATE TO IMPROVE PREDICTION OF SATURATED VAPOR PRESSURES AND SATURATED VOLUMES OF ALKANES[J]. CIESC Journal, 1997, (2).DOI:
SRK equation of state(EOS) is modified to improve the prediction of vapor pressures and saturated liquid volumes of alkanes (C1 -C20). The new generalized correlations for calculating the parameters n and m in the α ( T) function as well as C and S used for volume translation method are proposed. The modified SRK EOS is applicable for calculating the vapor pressures and saturated volumes from friple point to critical point
