Hengstebeck Diagrams Construction

End points. These can be calculated from the overhead and bottom 

Example Calculate the and points and the slope of the operating line for Example 2.4. 

Vapor and liquid flow rates are set in a manner similar to the binary calculation (Sec, 2.2.4), that is, 

Calculate the limiting vapor and liqnid flows for each section using Eqs. (2.64c), (2.64d), (2.65c), and (2,55d). Use these to determine the slopes of the component balance lines.
