Volume‐translated equations of state: Empirical approach and physical relevance

摘要: The volume translation technique is widely applied in chemical engineering modeling of phase behavior and thermodynamic properties. This empirical correction the molar improves correlation liquid densities when cubic equations state are employed. Based on a recently proposed method analyzing state, influence properties obtained from an equation such as virial coefficients, well behavior, critical properties, isobaric thermal expansion coefficient, heat capacities pure substances investigated. different kinds temperature-dependent translations investigated compared to approaches that originate theoretical considerations. investigation shows for development can exhibit nonphysical behavior. However, understanding reasons problems help develop reliable based both method.
