Follow these steps to start the calculation

Main Panel

Main Panel consists of following four control buttons :

• Data
• Result
• Draw Stages
• Detach

Data Button

On clicking of this button a window will appear to select properties for the binary mixture.

• Select from Ideal and Non-Ideal system
• Select Component from the Drop down List
• Or Manually Enter the Chemical Properties in the Table
  • Enter the Component Name
  • Enter the Antoine equation parameters A,B,C for the equation
    log10(P) = A-B/(T+C), where P is in bar, T is in degree C.
  • If Non-Ideal liquid behaviour is to be considered then enter Liquid Molar Volume, Vi ( in cm3/gm-mol ). Enter the Wilson interaction parameters in (cal/mol).
• Enter the Plot Data
  • Select type of Plot from Pxy, Txy, xy
  • Enter the values for which plot is to be made. Three values can be provided for which plots will be made
• After entering the data Click Draw Graph to start calculation and plotting of diagrams.

Result Button

On clicking of this button a window will appear with tabulated values of the selected curve. Data can be viewed for 10 and 100 data points.



To Copy data follow these steps -

• Press CTRL + A to Select all text matter in the text window.
• Press CTRL + C to Copy the selected text matter.
• Open any Text or Spreadsheet editor and press CTRL + V to Paste the selected Text.

Draw Stages Button

This button gets activated only when x-y Curve is selected and is being plotted for 1 variable only. On clicking this button a window will appear to collect data for calculation of Mc-Cabe Thiele stages.

• xF, Feed Mol fraction
• xD, Top Product Mol fraction
• xB, Bottom Product Mol fraction
• R, Reflux Ratio
• q, Quality of Feed, it defines whether feed is liquid, vapor or mixture of both

After entering the required data Click Calculate button to start calculation and plotting of stages in the x-y Diagram.

Detach Button

This button will start the application in a separate window, which can be resized to get a better view of the diagrams.
