Classification of scalar property isoline diagrams of homogeneous ternary mixtures

Abstract

The necessity of creating a classification has been substantiated for scalar property isolines dia grams of ternary systems having different numbers of singular points per element of the concentration sim plex. The total number of possible diagrams has been determined, and the topologically feasible diagram structures containing two singular points per open element of the concentration simplex have been synthe sized.

Classification for ternary flash point mixtures diagrams regarding miscible flammable compounds

“…By creating an auxiliary VLE system associated to a given closedcup flash point system, it was possible to extend the main results of the VLE theory to propose a classification of the flash point temperature diagrams for ternary miscible flammable mixtures analogous to the Serafimov isotherms classification [27]. This classification, shown in Fig.…”

“…In view of the duality between the location and the type of singular points of the RCM and the critical points of the corresponding boiling temperature, it is possible to classify the feasible topological classes of the VLE systems according to the type of the boiling temperature critical points and the shape of the isotherm curves instead of the residue curves, as it was proposed in Serafimov et al (2012) [27]. In the next section we extend this approach to the flash point temperature surfaces of flammable systems.…”

“…Rather, the set of all topologically feasible flash point surfaces is identical to the set of all topologically feasible boiling temperature surfaces. Thus, the Serafimov's classification of the topological structure of isotherms of ternary VLE systems [27] can be extended to the flash point temperature level sets. It concerns in theory mixtures with no flash point extremum, with minimum flash point behavior, with maximum flash point behavior or with maximum minimum flash point behavior.…”
