Recently, the methods has been applied also to many ternary systems. In this manner equilibrium diagrams have been determined for a number of binary systems. Consequently, these methods are utilized also for systems which have not been experimentally studied. However, in the case of some types of systems, the application of wellfounded assumptions and simplifications affords results consistent with the experimental ones. There is no general calculation method being common for various systems. This can be achieved either by means of time and laborconsuming measurements which permit plotting the equilibrium diagram, or more frequently means of theoretical calculations of equilibrium curves on the basis of the thermodynamics of nonideal solutions. Since different techniques for growing alloy crystals have already been developed, it is now of interest to determine the dependence of the concentration on temperature. Control of the composition of the alloy permits gaining control of its electronic properties. They show the interesting property of the dependence of the energy gap on alloy composition, which has been intensively investigated for the TeSn Pb system. systems, among which tellurium alloys represent the most numerous group, are increasingly often employed, mainly in electronics, both in the crystalline and noncrystalline states. the basis of the theory of regular associated solutions the equilibrium phase diagram of the ternary system TeBiSb was calculated by Laugier s method. calcule le diagramme de l équilibre liquidesolide dans le système ternaire TeBi Sb par une théorie de solution régulière associée, utilisée par Laugier Abstract.

Phase diagram calculation in the TeBiSb ternary system. Solvent can be either the heavy or the light phase (extraction), and solute can be either the heavy or the volatil component (distillation).1 Phase diagram calculation in the TeBiSb ternary system J. Solute equilibium in the two phases is represented on mass ratio (or mass fraction) diagram.Ī column with agitated compartments, test, final and emptying tanks with two phases management in each of them.Īutomatic transfer of test to final tanks, level control interface, cascade compositions control (extract and raffinate) on input feeds.Ī packed column for liquid-liquid extraction, with two peristaltic pumps and gravity feed flowrate, hydraulic seal for the interface level, recipes for heavy phase and light phase, and outlet valves and bypass to final tank.Ĭoupled extraction and distillation columnĪn agitated extraction column, coupled to a distillation column for solvent and solute separation, and solvent recycle to the extraction. Q: no dynamics in this model, response time of mixing decanters being usually long due to high residence time!įor these models, solvent and diluent are considered non miscible. They can be displayed on equilateral or rectangular ternary diagram, or on the curve representing mass ratios in the two phases. Extraction stages may be counter-current or cross flow. This model solves the material balances (solute, solvent, diluent) and equilibrium of a liquid-liquid extraction with N theoretical stages. You can make your own extraction experiment, and see the representative points on the ternary diagram in real time.
