P of Pure Species Based on Pressure-Explicit EOSs

l f P OF PURE SPECIES BASED ON PRESSURE-EXPLICIT EOSs 

The general approach to calculating fugacities from pressure-explicit EOSs is to use integration by parts to replace the vdP integral. 

When this is substituted in Eq. 7.9, and we observe that at the lower limit the ideal gas law applies, then we have 

To perform the integration (and simplify the problem of lower integration limits of zero and infinity), we add and subtract H RT /v)dv to the right-hand side of Eq. F.3 and factor to
