CPA (Cubic-Plus-Association) is an equation of state that is based on a combination of the SoaveRedlichKwong (SRK) equation with the association term of the Wertheim theory. The development of CPA started in 1995 as a research project funded by Shell (Amsterdam), and the model was first ...
CPA equation of statemodelingthermodynamicAsphaltene precipitation during natural depletion and miscible gas injection is a common problem in oilfields throughout the world. Therefore, predicting asphaltene phase behavior through thermodynamic modeling may help to control its precipitation and reduce the ...

The cubic-plus-association (CPA) equation of state (EoS) is applied, using different combining rules, to vaporliquid equilibria (VLE) and liquidliquid equilibria (LLE) of alcoholwater systems. It is demonstrated that the Elliott combining rule (ECR) with a common temperature-independent interaction...
