Demixing phenomena in liquid ternary systems are widely used in chemical engineering processes. When a critical point is observed, the composition of this invariant point of major interest is experimentally difficult to determine. A simple calculation method for the critical point is proposed using the experimental tie-lines. The computing treatmen...
Conference Paper
Refining has significantly improved its energy performance in the last 20 years. However, refineries are still working on improving the efficiency of refining processes, to be more competitive. In this context, Total, one of the largest integrated international oil and gas companies, is making efforts to improve its refineries’ energy efficiency. T...

In many cases of miscibility gap in ternary systems, one critical point at least, stable or metastable, can be observed under isobaric and isothermal conditions. The experimental determination of this invariant point is difficult but its knowledge is essential. The authors propose a method for calculating the composition of the invariant solution s...

... Nevertheless, it has to be noticed that for liquid-liquid calculation, there is an extreme sensitivity to the excess Gibbs enthalpy (or activity coefficients), which means, among other things, that the quality of the calculation of the critical point highly depends on the quality of the fitting of the experimental tie-lines data with the model. Previous studies have resulted in a semiempirical determination method for this specific point of the binodal curve (Goutaudier et al., 2013 Greek letters barycentric weighting parameteř power of the internodal distance in the modulus method ı conode slope  arctangent ı Ä critical point rectilinear diameter method, allows us to get away from these disruptions and explains its success (Reif-Acherman, 2010). The rectilinear diameter law was originally formulated at the end of the 19th century by Cailletet, who studied the behaviour of fluids under high pressures and tried to determine the critical volume of liquefied pure substances Mathias, 1886, 1887). ...
