where parameter(k) is one of {r∏i∕Mwi,σi,ti∕k'). The coefficients of the correlations
are given in table 2.3. The correlations are also plotted in figure 2.6. These correla-
tions are used to extrapolate the parameters for higher alkanes.

SAFT-D parameters on molecular weight of n-alkanes.

Figure 2.7 compares experimental saturated liquid densities of tetracosane(n-
C24), triacontane(n-C30), and hexatriacontane(n-C36), with those calculated from
PC-SAFT and the new equation of state using extrapolated parameters. The new
EOS performs better than PC-SAFT and give reasonably accurate densities for all
three components in the range of temperature considered.
