I went through '''file''' menu and the '''open''' option to get this.

Let me close this.

This file is available at our spoken tutorial website.

You may download this and use it.

Or you can manually enter the required information.

You can see two streams '''Inlet1''' and '''Inlet2''' in the flowsheet canvas.

|-
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| <center>Slide 5</center>
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| The next slide summarises the contents of this file.

When we mix these streams, we get equimolar composition.

We have chosen these values to easily verify the calculations of '''DWSIM'''.

| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| The '''mixer''' is red, as it is not calculated yet.

To the right of the '''configure simulation''' tab is '''calculator.'''

It has several options.

| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| Two buttons to the right of this is for '''Recalculate '''action.

Click this button.

The '''mixer''' has become blue now.It means that the calculations are completed.

|-
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| <center>Click on '''mixer-out '''and hover mouse at '''Properties'''</center>
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| Now click on '''mixer-out''' stream.

We can see its calculated values in the '''Properties''' tab.

We can verify that its composition is as expected. Double click '''Mixture'''

It has equimolar composition.

|-
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| <center>Click and drag '''Separator Vessel''' to the flowsheet</center>
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| Now let us insert a flash separator.

Let us scroll down the '''Object Palette.'''

Let us scroll down and locate the '''Separator Vessel.'''

It can be used to simulate VLE, LLE and VLLE systems.

Click and drag it to the flowsheet.

|-
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| <center>Click and drag '''Material Stream''' to the flowsheet</center>
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| We need to connect two output streams to the separator.

Let us drag the '''material stream'''.

We will leave it unspecified, as its properties are to be calculated.

|-
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| <center>Type '''Vapour'''</center>
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| We will name it as '''Vapour'''.

|-
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| <center>Type '''Liquid'''</center>
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| Similarly, create another stream and name it as '''Liquid.'''

|-
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| <center>Connect '''mixer-out '''stream to '''Inlet stream1 '''port</center>



| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| Let us now connect the streams to the '''Separator.'''

In the first input port, we will connect '''mixer-out. '''

We can connect a total of five more input streams.

The '''separator '''mixes all the streams and separates.

As a matter of fact, a separate mixer is not really required.

It also has a port to connect an '''energy stream'''.

As we can see.

These ideas will be taken up in the assignment section.

|-
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| <center>Connect '''Vapour '''stream to '''Vapour outlet''' port</center>
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| Let us connect the '''Vapour '''stream to the '''Vapour outlet''' port.

|-
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| <center>Connect '''Liquid '''stream to '''Liquid outlet''' port</center>
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| Similarly, connect the '''Liquid''' stream.

Once again, we can move the items for better alignment.

|-
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| <center>Hover the mouse at '''Recalculate'''</center>
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| Notice that '''DWSIM''' completed the calculations automatically.

You are free to press the '''Recalculate''' button also.

In fact you should do this whenever you are in doubt.

|-
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| 
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| We now check whether the vapor and liquid are split properly in the separator.

|-
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| <center>Click '''Vapor '''stream and hover mouse at '''Molar compoition'''</center>
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| Let us look at the vapor phase mole fractions of the stream '''Vapour.'''

The mole fraction of '''Benzene''' is '''0.54.'''

|-
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| <center>Click '''mixer-out''' and hover mouse at '''Molar compoition'''</center>
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| Let us check whether this is in agreement with what '''mixer-out''' has.

You can see that '''DWSIM '''automatically displays '''vapor''' value

'''benzene mole fraction''' is 0.54.

This is an indirect evidence that the '''Separator''' is working as expected.

We can do a check on the working of the '''Mixer '''also'''.'''

You can see the '''Mixture''' composition is equimolar, as expected.

|-
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| 
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| We will postpone a few other checks to the Assignment Section.

|-
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| <center>Click on '''File '''and Click '''Save As'''</center>
| style="background-color:#ffffff;border:0.75pt solid #cccccc;padding-top:0cm;padding-bottom:0cm;padding-left:0.191cm;padding-right:0.191cm;"| Let us save this file now using the '''save as''' option.
