Abstract
 

The Thermodynamic Modeling Framework (TMF) for LNG systems is obviously not available and its focal point is the development of robust methods for thermodynamic stability analysis as well as algorithms for accurate phase split predictions. A new model is here developed with its algorithm and applied to a Nitrogen-rich LNG system. Two EOS models were used with initial With Peng-Robinson EOS model, 2-phase split occurred at 110.8K, 3-phase–split occurred at 110.9K while the system reverted to 2 phases at 111K without further changes. For the Soave-Redlich-Kwong EOS model, the system split into 2 phases at110.8K, into 3 phases at 11K but reverted and remained a 2-phase system at 111.8K.
