Multiphase equilibria of waxy systems with predictive equations of state and a solid solution model

Abstract A thermodynamic model is developed to predict the vapor-liquid, solid-liquid, solid-vapor and solid-liquid-vapor equilibria of systems containing methane with waxy components. The model takes the advantages of equations of state to describe the vapor and liquid phases. The solid phase i...
