Reading Ternary Phase Diagrams
In the below diagram the top vertex is 100 acetic acid the bottom left is 100 water and the remaining one is 100 chloroform. The three components are usually compositions of elements but may include temperature or pressure also.
A ternary phase diagram has three components.
Reading ternary phase diagrams. Hidden on the back of the plot. For the moment they are labeled A B and C. It is common to group C1 and N 2 as the light L CO 2 H 2 S and C 2 C 6 as the intermediate I and C 7 as the heavy H fraction.
Ternary phase diagrams Phase diagrams are graphical representations of the liquid vapor and solid phases that co-exist at various ranges of temperature and pressure within a reservoir. This type of diagram is three- dimensional but is illustrated in two-dimensions for ease of drawing and reading. We are going to take the diagram apart to see how it works.
How to read the ternary phase diagram to determine the compositions. Reading a ternary diagram sepm strata a ternary diagram is a triangle with each of the three apexes representing a position such as sandstone shale and limestone for the moment they are labeled a b and c we are going to take the diagram apart to see how it works the drawing to the left has only the skeleton of the triangle present as we concentrate on point a. A ternary diagram is a triangle with each of the three apexes representing a composition such as sandstone shale and limestone.
Draw a line parallel to the base that is opposite the 100 point through the point you wish to read. Each of the vertices of the triangle is a 100 pure substance. For the moment they are labelled A B and C.
A B and. The composition of the liquid is given by reading the composition of point M off the basal triangle. There are too many degrees of freedom for a two-dimensional plot.
A consistent and dependable method for reading a ternary diagram includes four steps. The following phase diagram is of acetic acid water and chloroform. First note that phase diagrams similar to any of the above could be presented on an exam and.
Remember the phase rule FC2-P. 192 Phase DiagramsUnderstanding the Basics. The axis values increase from the base opposite this point to the 100 point.
Phase diagram Pressure-temperature phase diagram for H2O. We often examine liquid-liquid extraction using a ternary phase diagram. Figure 1 shows a three dimensional representation of the three component ternary system ABC.
This diagram contains two binary eutectics on the two visible faces of the diagram and a third binary eutectic between ele-ments. We are going to take the diagram apart to see how it works. Is shown in Fig.
C A B. Note that composition is measured along the sides of the basal triangle and temperature or. This triangle is a section cut from a three-dimensional figure at a given temperature fixing temperature uses up a degree of freedom.
One op- tion is to add a third composition dimension to the base forming a solid diagram having binary dia- grams as its vertical sides. Ternary Phase Diagrams Crystallization in Ternary Systems I. The drawing to the left has only the skeleton of the triangle present as we concentrate on point A.
Ternary Diagrams When a third component is added to a binary system illustrating equilibrium conditions in two dimensions becomes more compticated. For one component systems the equilibrium state of the system is defined by two independent parameters P and T T and V or P and V. Understanding Phase Diagrams VB.
The ternary phase diagram contains a lot of information on the phase behavior of the mixture of three components. Equilibrium Crystallization Where all 2 Component Systems are Binary Eutectic Systems. Ternary phase diagrams represent the phase behavior of mixtures containing three components in a triangular diagram.
Locate the 1 or 100 point on the axis. Ternary phase diagram books by DRF. Reading a ternary phase diagram A ternary diagram is a triangle with each of the three apexes representing a composition such as sandstone shale and limestone.
West there are several. The ternary phase diagram of a multicomponent reservoir fluid is often expressed by representing the fluid with three pseudo components. Since it is a mixture of A B and C it will have a composition expressed in terms of the percentages of A B and C.
However it also contains considerable information on the phase behavior on the three binary mixtures A B B C and A C that is implied by examining the edges of the diagram and the intersecting regions of phase equilibria. Reading a Ternary Diagram Three-component phase diagrams can be equilateral triangles. Usually have elements at the corners as the constituents.
Ternary diagram of acetic acid water and chloroform. Because it is difficult to use. Phase diagramis a graphical representation of all the equilibrium phases as a function of temperature pressure and composition.
A hypothetical ternary phase space diagram made up of metals.
