The Mass Balance Triangle MBT

With this condition, only — 1) entries in a compositional vector are needed to fully define it. Thus, for example, a 3-component system only requires mole fractions of two components for it to be fully specified. The remaining component is inferred by unity summation property in Equation 2.2. 

Suppose the stiU is charged with a ternary mixmre comprising of arbitrary components such that 

Component 2 is a high-boiling (or least volatile) component, and 

Another related, but more important plot is that of the change of each species composition with each other, where each point along the profile is measured as time
