As simulations are important for the optimisation and the operation of a process a highly accurate representation of thermodynamic properties is needed. To assure that these demands are met an appropriate property model must be used. The GERG-2004 XT08 [1] is the new reference equation of state for natural gases, which describes the whole fluid phase. In order to model LNG processes with the highest accuracy possible the new equation is implemented into several simulation tools. Researches on the influence of property models on the simulation of LNG transport and vaporisation processes show the expected advantages in accuracy with the GERG-2004 XT08 [1] in comparison with typical engineering equations of state.
