A correlation based on the general form of cubic equations of state has been derived. This equation provides a convenient mathematical form of the Joule-Thomson coefficient in terms of the state variable V and T. The Joule-Thomson coefficient calculated by this correlation has been compared with experimental data. It has been shown that the Redilich-Kwang equation of state is a suitable equ...

asphaltenes are the n-pentane or n-heptane insoluble fractions of crude oil that remain in solution under reservoir temperature and pressure conditions. they are destabilized and start to precipitate when the pressure, temperature and/or composition changes occur during primary production. the precipitated asphaltene particles will then grow in size and may start to deposit onto the production ...

Air is one of the most important substances used in industrial and technological applications. Applications air require a consistent set reliable data on its thermodynamic thermophysical properties. Over last few decades, researchers have developed number empirical theoretical models for correlation prediction properties pure fluids mixtures. The ideal gas Equation State (EoS) property calculat...
