Simplified Crossover SAFT Equation of State to description of supercritical thermodynamic and transport properties

Accurate prediction of the critical properties and evaluation of the phase behavior of puresubstances and mixtures are the basis for developing and improving equations of state (EsoS).Nevertheless, the classical EsoS do not predict universality of the critical point, so subsequentstudies attempted to achieve this universality. Based on the renormalization group (RG)method calculations developed a theoretical approach for constructing a crossover expressionfor the thermodynamic potential of a system in the critical region. A most general procedurefor transforming any classical EoS into the crossover form was proposed by Kiselev [1]. Thisprocedure has a theoretical foundation in the RG theory and has been successfully applied tothe statistical associating fluid theory (SAFT) EoS. In this work we continue our study of thesimplified crossover SAFT EoS initiated in Kiselev and Ely [2] to calculate supercriticalthermodynamic and transport properties of R12 (as a sample of refrigerants).
