Introduction Previous section we introduced the concept of vapour-liquid equilibrium and its application in predicting multicomponent behaviour with respect to reservoirs. In this section we will review the methods used to determine K values, which are at the foundation of VLE prediction methods.

Introduction Compared to process facility calculations in petroleum engineering detailed definition of the composition of the fluid is not available. Some of these undefined components may have significant impact on VLE behaviour. The fluid in a reservoir is unique from its composition perspective.

Process versus reservoir compositional modelling Process Engineering Calculations for a single unit or a few in series. Full compositional data is available. Calculations to predict detailed compositional outcome. Reservoir Engineering Calculations part of a multi- grid block simulation. Hundred or thousand of process units. Limited compositional data. Calculations to predict phase volumes and physical properties.

Petroleum Engineering Vapour Liquid Equilibrium Challenge Prediction of properties based on limited data Applicable to multi-component mixtures Accurate at predicting thermodynamic and volumetric properties over a wide range of pressures and temperatures and around and beyond critical point. Be able to use pure component or binary mixture data which is available from literature or generated.
