|-<br />
|| <br />
|| Now maximize the '''Simulation''' window.<br />
|-<br />
|| Click and drag '''Material Stream '''to the flowsheet<br />
|| Now let’s insert a '''feed stream''' that has to be distilled. <br />
|-<br />
|| Point to '''Streams.'''<br />
|| At the bottom of the main '''simulation''' window, go to '''Streams.'''<br />
|-<br />
|| Click and drag '''Material Stream '''to the flowsheet <br />

|-<br />
|| Type '''Feed'''<br />
<br />
Press '''Enter'''.<br />
|| Let’s change the name of this '''stream''' to '''Feed.'''<br />
<br />
Press '''Enter'''.<br />
|-<br />
|| <br />
|| Now we will specify the '''Feed stream''' compositions.<br />
|-<br />
|| '''Input Data '''>>''' Compound Amounts'''<br />
|| For this under '''Input Data''' click on '''Compound Amounts''' tab.<br />
|-<br />
|| '''Basis >> Mole Fractions'''<br />

|| Click '''Molar flow'''<br />
|| Change '''Molar flow ''' to '''100 Kmol/h '''and press '''Enter.'''<br />
|-<br />
|| Click '''Vapor Phase Mole Fraction'''<br />
|| Now locate '''Vapor Phase Mole Fraction.''' <br />
<br />
Here the default value is '''0.''' <br />
<br />
This indicates that the liquid is saturated.<br />
<br />
Let us leave it as it is. <br />
|-<br />
||<br />
|| Now let us insert a '''Shortcut Column '''into the '''flowsheet'''. <br />
|-<br />
|| Click and drag '''Shortcut column''' to the flowsheet<br />
|| At the bottom of the main '''simulation''' window, go to '''Columns '''tab.<br />
<br />
The '''Shortcut Column''' is based on '''Fenske-Underwood-Gilliland''' method. <br />
|-<br />
|| Click and drag '''Shortcut Column '''to the flowsheet <br />
|| From the displayed list, drag and drop a '''Shortcut Column '''to the '''Flowsheet'''<br />
|-<br />
||<br />
|| Now let us insert two '''output streams.''' <br />
|-<br />
|| Click and Drag '''Material Stream '''to the flowsheet <br />
|| To do that, let us drag one '''Material Stream.'''<br />
|-<br />
||<br />
|| Leave that '''stream''' as unspecified. <br />
|-<br />
|| Type '''Distillate'''<br />
|| Then we will change the name of this '''stream '''to '''Distillate.'''<br />
|-<br />
|| Click and drag''' Material Stream '''to the flowsheet <br />
|| Next, we will insert another '''Material Stream.'''<br />
|-<br />

|| Let us now insert two '''Energy streams '''for '''Condenser duty '''and '''Reboiler duty.''' <br />
|-<br />
|| Click and drag '''material stream''' to flowsheet<br />
|| Go to '''Streams''' tab.<br />
<br />
From the displayed list, drag and drop two '''Energy Streams''' to the '''Flowsheet'''. <br />
|-<br />
|| <br />
|| Let us now arrange it as required.<br />
|-<br />
|| Click on stream.<br />
<br />
Go to the '''Property Editor Window'''<br />
<br />
Type '''C-Duty '''and '''R-Duty'''<br />
|| Name these '''streams''' as '''C-Duty '''and '''R-Duty.''' <br />
|-<br />
|| Click '''Shortcut distillation column'''<br />
|| We are now ready to specify the '''Shortcut distillation column.''' <br />
<br />
So let’s click on it. <br />
|-<br />
|| Point to the tab on the left. <br />
|| On the left, we can see a tab displaying properties related to the '''Shortcut Column.'''<br />
|-<br />
|| Go to '''Connections'''<br />
<br />
Click on drop down arrow against '''Feed Stream'''<br />
<br />
Select''' Feed.'''<br />
|| Under '''Connections,''' click on the drop-down against '''Feed Stream.'''<br />
<br />
Select '''Feed.'''<br />
|-<br />

|-<br />
||<br />
|| This completes the connectivity of the '''flowsheet'''. <br />
|-<br />
|| Point to '''Calculation Parameters'''<br />
|| Now, go to the '''Calculation Parameters.'''<br />
<br />
This section is used to specify various attributes of a '''Shortcut Column'''. <br />
|-<br />
|| Click on drop down arrow against '''Light Key Compound (LK)'''<br />
<br />
Select''' Benzene.'''<br />
|| Click on the drop-down against '''Light Key Compound (LK)''' and select '''Benzene.'''<br />
|-<br />
|| Click on drop down arrow against '''Heavy Key Compound (HK)'''<br />
<br />
Select''' Toluene.'''<br />
|| Click on the drop-down against '''Heavy Key Compound (HK)''' and select '''Toluene.'''<br />
|-<br />
|| Hover mouse at '''Properties, Parameters, Condenser type'''<br />
|| Now go to '''Condenser Type.'''<br />
<br />
By default, it is '''Total Condenser. '''<br />
<br />
If a '''partial condenser''' is required, we can change it here. <br />
|-<br />
|| '''LK Mole Fraction in Bottoms >> 0.01'''<br />
<br />
'''Press Enter'''<br />
<br />
|| Click on the field against '''LK Mole Fraction in Bottoms''' and enter it as '''0.01''' and press '''Enter.'''<br />
|-<br />
|| '''HK Mole Fraction in Distillate >> 0.01'''<br />
<br />
'''Press Enter'''<br />
|| Click on the field against '''HK Mole Fraction in Distillate''' and enter it as '''0.01'''<br />
<br />
Then press '''Enter.'''<br />
|-<br />
||<br />
|| Let us go back to the slides.<br />
|-<br />
|| '''Show Slide'''<br />
<br />
'''Highlight 1.4'''<br />
|| Recall that we want our '''reflux ratio''' to be '''1.4 '''times the minimum''' reflux ratio.'''<br />
<br />
So let us check the minimum''' reflux ratio.'''<br />
|-<br />
|| <br />
|| For this, let us run '''simulation''' once.<br />
|-<br />
|| Click '''Solve Flowsheet'''<br />
|| To do this, click on '''Solve Flowsheet''' button.<br />
|-<br />
||<br />
|| Click on the '''Distillation Column'''.<br />
<br />
|-<br />
|| <br />
||From the '''Property Editor Window''', locate '''Results''' section. <br />
|-<br />
|| '''Results''' >> '''Minimum Reflux Ratio'''<br />
<br />
'''Actual Reflux Ratio = 1.655*1.4 = 2.317'''<br />
|| Now we can see that '''Minimum Reflux Ratio''' is '''1.655'''.<br />
<br />
So the actual '''Reflux Ratio''' will become '''2.317'''.<br />
|-<br />
|| Hover mouse at''' Results '''>>''' Actual Number of Stages, Optimal Feed Stage'''<br />
|| Next let us enter the''' reflux ratio. '''<br />
<br />
Look at the '''Shortcut Column''' results.<br />
<br />
Here note the '''Actual Number of Stages''' and '''Optimal Feed Stage'''.<br />
<br />
We can see that these values are '''NaN'''.<br />
<br />
This is because the default value of '''reflux ratio '''is '''1.5'''.<br />
<br />
It is less than minimum '''reflux ratio'''.<br />
|-<br />
|| '''Reflux Ratio''' >> '''1.655*1.4''' and ress '''Enter'''<br />
<br />
'''Reflux Ratio: 2.317'''<br />
|| Now let us enter the '''Reflux Ratio.''' <br />
<br />
Enter the value as '''1.655*1.4''' and press '''Enter.'''<br />
<br />
Now the '''Reflux Ratio''' is '''2.317.<br />
|-<br />
|| '''Condenser Pressure >> 1 atm'''<br />
<br />
'''Press Enter'''<br />
<br />
|| Click on the field against '''Condenser Pressure''' and enter it as '''1 atm'''<br />
<br />
and press '''Enter.'''<br />
|-<br />
|| '''Reboiler Pressure >> 1 atm'''<br />
<br />
'''Press Enter'''<br />
<br />
|| Click on the field against '''Reboiler Pressure''' and enter it as '''1 atm '''.<br />
<br />
Then press '''Enter.'''<br />
|-<br />
||<br />
|| Now we will run the '''simulation'''. <br />
|-<br />
|| Click '''Solve Flowsheet'''<br />
|| To do this, click on the '''Solve Flowsheet''' button on the toolbar.<br />
|-<br />
|| Click on the '''Shortcut column''' <br />
|| When calculations are completed, click on the '''Shortcut column.''' <br />
|-<br />
|| Hover mouse at '''Properties, Results'''<br />
|| From the '''Property Editor Window''', locate '''Results '''section. <br />
<br />
This shows the all required results like:<br />
<br />
'''Minimum Reflux Ratio'''<br />
<br />
'''Minimum Number of Stages'''<br />
<br />
'''Actual Number of Stages'''<br />
<br />
'''Optimal Feed Stage'''<br />
<br />
'''Condenser Duty, Reboiler Duty, etc'''<br />
|-<br />
|| '''Slide Number 8'''<br />
<br />
'''Results'''<br />
|| I have tabulated these results in a slide. <br />
|-<br />
|| <br />
|| Let us go back to the simulation.<br />
|-<br />
|| Click '''File '''and '''Save As >> '''File name = '''shortcut-end'''<br />
|| Let me save this. <br />

'''Summary'''<br />
|| In this tutorial, we have learnt to:<br />
* Simulate a '''Shortcut distillation''' column <br />
* Calculate '''Minimum number of stages '''<br />
* Calculate '''Minimum reflux ratio''' <br />
