In practice, vapor/liquid reservoir phase behavior is calculated by an equation of state (eos) the two most common eoss that have been used for oil-recovery solvent. The equation of state relates the pressure p, volume v and temperature t of a physically homogeneous system in the state of thermodynamic equilibrium f(p, v, t) = 0. Density and the equation of state • accurate measurements of density can only be done in the lab, not in situ (no density sensor) • therefore, density is usually. In the literature there are several studies comparing the accuracy of various models in describing the pvt behavior of polymers however, most of these.
Define equation of state: an equation that expresses the relation between the pressure, temperature, and volume of a gas or liquid. Although usually not the most convenient equation of state, the virial equation is important because it can be derived directly from statistical mechanics.
