Other Equilibrium Diagrams: P – T diagram Phase Equilibrium (Recommendations) Mixtures to model: Vapor Liquid Equilibrium (VLE) Vapor phase: good liquid phase: good for HC or moderate – high pressures (compressible liquid phase) Typically used for liquid phase fugacity calculations Used for special cases (like gases dissolving into liquid phase) Equations of state models Activity coefficient models Phase Equilibrium (Alternate Form VLE) Historically, when estimates were done by hand: Sometimes the K values are nearly composition independent “hand” techniques of design/solution have used DePriester Charts (hydrocarbons):ĭePriester Chart P = 2 bar T = 100 oC Isobutane others….
