Polar perturbed-hard-chain statistical-association fluid theory
This is an extension of the PC-SAFT EOS: Terms have been added that account for dipolar and quadrupolar electrostatic interactions.
adjustable parameters: 3 (The dipole moment, the quadrupole moment, and the polarizability are not considered adjustable.)
The critical compression factor is too high; the EOS should not be fitted to the critical volume.
The latest—and also recommended—version is PCP-SAFT2008. The older versons PC-SAFTP1, PC-SAFTP2, and PCP-SAFT2006 are merely kept for comparison.
