  2. Phase diagram - Wikipedia

    en.wikipedia.org/wiki/Phase_diagram

    The phase diagram shows, in pressure–temperature space, the lines of equilibrium or phase boundaries between the three phases of solid, liquid, and gas. The curves on the phase diagram show the points where the free energy (and other derived properties) becomes non-analytic: their derivatives with respect to the coordinates (temperature and ...

  3. Lever rule - Wikipedia

    en.wikipedia.org/wiki/Lever_rule

    Tie line in the Alpha plus Liquid two phase region. There is now more than one two-phase region. The tie line drawn is from the solid alpha to the liquid and by dropping a vertical line down at these points the mass fraction of each phase is directly read off the graph, that is the mass fraction in the x axis element.

  4. Compatibility diagram - Wikipedia

    en.wikipedia.org/wiki/Compatibility_diagram

    A three-component compatibility diagram will depict the stable phase of each pure component as the point at each corner of a ternary diagram. Additional points in the diagram represent other pure phases, and lines connecting pairs of these points represent compositions at which the two phases are the only phases present.

  5. Tie line - Wikipedia

    en.wikipedia.org/wiki/Tie_line

    Tie line may refer to: Tie line (telephony), a circuit between two telephone exchanges. Tie line (electrical grid), an electrical circuit connecting balancing authorities. Tie line, an isothermal line through a two-phase region on a phase diagram.

  6. Ternary plot - Wikipedia

    en.wikipedia.org/wiki/Ternary_plot

    A ternary flammability diagram, showing which mixtures of methane, oxygen gas, and inert nitrogen gas will burn. A ternary plot, ternary graph, triangle plot, simplex plot, or Gibbs triangle is a barycentric plot on three variables which sum to a constant. [1] It graphically depicts the ratios of the three variables as positions in an ...

  7. Schreinemaker's analysis - Wikipedia

    en.wikipedia.org/wiki/Schreinemaker's_analysis

    A generic phase diagram with unspecified axes; the invariant point is marked in red, metastable extensions labeled in blue, relevant reactions noted on stable ends of univariant lines. This rule is geometrically sound in the construction of phase diagrams since for every metastable reaction, there must be a phase that is relatively stable. This ...

  8. McCabe–Thiele method - Wikipedia

    en.wikipedia.org/wiki/McCabe–Thiele_method

    The typical McCabe–Thiele diagram in Figure 1 uses a q-line representing a partially vaporized feed. Example q-line slopes are presented in Figure 2. The number of steps between the operating lines and the equilibrium line represents the number of theoretical plates (or equilibrium stages) required for the distillation. For the binary ...

  9. File:TernaryExample.svg - Wikipedia

    en.wikipedia.org/wiki/File:TernaryExample.svg

    This is a very basic ternary diagram in svg for hypothetical components A, B, and C. I'm hoping that someone (perhaps me when I have time) will use this base for a more thorough explanation of ternary phase diagrams.
