文摘

A modified Cubic Plus Quadrupole Equation of State (mqCPQ EoS) was used for polymer-supercritical CO2 systems. mqCPQ EoS consists of two terms as SRK and Quadrupole-Quadrupole. The cloud point pressures were calculated for scCO2 with with polymers of PLA, P(AcGlcVE) and PVAc-alt-PDBM. The pure component parameters of mqCPQ EoS are calculated through LLE calculation. The results of mqCPA are compared with both PC-SAFT and PCP-SAFT EoSs.
