Rp. Stateva et Sg. Tsvetkov, APPLICATION OF A NEW ALGORITHM FOR PREDICTION AND MODELING OF MULTIPHASE BEHAVIOR - A CASE-STUDY OF SOME PROTOTYPE NATURAL-GAS SYSTEMS, Collection of Czechoslovak Chemical Communications, 59(5), 1994, pp. 1038-1051
The prediction and modelling are studied of complex multiphase behavio
r of four prototype ternary mixtures typically encountered in cryogeni
c processing of natural gases, with a new approach for solving the iso
thermal multiphase flash problem. The method includes a rigorous metho
d for thermodynamic stability analysis as the first step and an effici
ent phase identification procedure as the second. The new algorithm pr
ovides an accurate global description of phase behavior of the studied
LNG systems, and excellent agreement of the results obtained with exp
erimental data.
