Molecular Structures And Thermodynamic Phase Equilibrium Models

Abstract

A great number of chemical engineering applications involve processes such as distillation, absorption,liquid-liquid extraction, etc. For the design of the necessary equipment to carry out these operations, it is important to have equilibrium data which is not always available. Therefore predictive models can be very useful and are necessary. Various models exist but the most accurate ones are those which take into account the nature and the size of the molecule. Consequently, this present work is an attempt to establish an eventual relationship between the thermodynamic models and the molecular structure, for chosen binary systems such as Hydrocarbons, Hydroxylic, Aromatic, etc.Known systems have been considered to validate the approach and examine any relationship between the molecular structure and the calculated property.
