| 00:01
| Welcome to the spoken tutorial on Introduction to Flowsheeting in '''DWSIM'''

|-
| 00:07
| In this tutorial,We will simulate a '''mixer'''

|-
| 00:10
| Follow it up with a '''flash separator'''

|-
| 00:12
| Learn how to give a two phase feed

|-
| 00:16
| To record this tutorial, I am using '''DWSIM''' 3.4.

|-
| 00:20
| To practice this tutorial, you should have an exposure to '''DWSIM'''.

|-
| 00:24
| The prerequisite tutorials are mentioned on our website, '''spoken''' hyphen '''tutorial''' dot '''org'''.

|-
| 00:31
| Let me open '''DWSIM'''.

|-
|00:33
| I have already opened a file '''flow-begin '''with two material streams.

|-
| 00:40
| I have selected '''Raoult’s''' law and the '''CGS system'''.

|-
| 00:43
| I went through '''file''' menu and the '''open''' option to get this. Let me close this.

|-
| 00:53
| This file is available at our spoken tutorial website.

|-
| 00:56
| You may download this and use it Or you can manually enter the required information.

|-
| 01:02
| You can see two streams '''Inlet1''' and '''Inlet2''' in the flowsheet canvas.

|-
| 01:08
| The next slide summarises the contents of this file.

|-
| 01:13
| When we mix these streams, we get equimolar composition.

|-
| 01:17
| We have chosen these values to easily verify the calculations of '''DWSIM'''.

|-
| 01:23
| Let us go back to '''DWSIM'''.

|-
| 01:25
| We will now modify the streams, so as to have vapor in them.

|-
| 01:31
| Select '''Inlet 1'''.

|-
| 01:34
| At the top of the '''Properties''' tab, locate '''Specification.''' Click on it.

|-
| 01:40
| Press the down arrow and choose '''Pressure and Vapor Fraction.'''

|-
| 01:46
| Scroll down and locate''' Molar Fraction Vapor Phase.'''

|-
| 01:53
| Enter '''1 ''' here, that is, the entire stream is a vapor.

|-
| 02:00
| In a similar way, make '''Inlet2''' to have 50% Molar Fraction.

|-
| 02:13
| Now let us insert a mixer to the flowsheet.

|-
| 02:17
| Locate the '''Mixer''' from the object palette. It is the third entry.

|-
| 02:22
| Click and drag it to the flowsheet.

|-
| 02:24
| Let us change the name of the mixer now.

|-
| 02:29
| Click on the '''Appearance''' tab. Delete the default name and enter '''Mixer.'''

|-
| 02:36
| Now let us insert an '''output '''stream for the mixer.

|-
| 02:40
| Click on '''Material Stream '''and drag it to the flowsheet.

|-
| 02:45
| We will close the automatic pop up, and not enter anything. Because, all output streams should be left unspecified.

|-
| 02:54
| We will change the name of this stream to '''mixer-out.'''

|-
| 03:03
| Let me connect the streams to the '''mixer.'''

|-
| 03:05
| Let me click the '''mixer''' once.

|-
| 03:08
|'''Properties''' show up in the '''Selected Object''' window.

|-
| 03:12
| You can see that the mixer has up to 6 inlet streams.

|-
| 03:19
| Let us click on '''Inlet Stream 1'''.

|-
| 03:23
| A down arrow appears, indicating a menu.

|-
| 03:27
| Click this arrow and Choose '''Inlet1.'''

|-
| 03:32
| Similarly, connect '''Inlet2''' at '''Inlet Stream 2.'''

|-
| 03:37
| Locate the outlet port, mentioned as '''Connected to Outlet''' here.

|-
| 03:43
| Click on it and choose''' mixer-out.'''

|-
| 03:49
| We can move the streams to make them better aligned.

|-
| 03:54
| The '''mixer''' is red, as it is not calculated yet.

|-
| 03:58
| To right of the '''configure simulation''' button is '''calculator.'''

|-
| 04:02
| It has several options.

|-
| 04:03
| The first one is the play button, to '''activate''' the solver. Press it.

|-
| 04:09
| Two buttons to the right of this is for '''Recalculate '''action.Click this button.

|-
| 04:17
| The '''mixer''' has become blue now, it means that the calculations are completed.

|-
| 04:22
| Now click on '''mixer-out''' stream.

|-
| 04:27
| We can see its calculated values in the '''Properties''' tab.

|-
| 04:31
| We can verify that its composition is as expected.

|-
| 04:37
|Double click '''Mixture'''

|-
| 04:40
| It has equimolar composition.

|-
| 04:43
| Now let us insert a flash separator.

|-
| 04:47
| Let us scroll down the '''Object Palette.'''

|-
| 04:51
| Let us locate the '''Separator Vessel.'''

|-
| 04:56
| It can be used to simulate VLE, LLE and VLLE systems.

|-
| 05:01
| Click and drag it to the flowsheet.

|-
| 05:06
| We need to connect two output streams to the separator.

|-
| 05:10
| Let us drag the '''material stream'''.

|-
| 05:13
| We will leave it unspecified, as its properties are to be calculated.

|-
| 05:20
| We will name it as '''Vapour'''.

|-
| 05:27
| Similarly, create another stream and name it as '''Liquid.'''

|-
| 05:32
| Let us now connect the streams to the '''Separator.'''

|-
| 05:36
| In the first input port, we will connect '''mixer-out. '''

|-
| 05:44
|We can connect a total of five more input streams.

|-
| 05:47
|The '''separator '''mixes all the streams and separates. As a matter of fact, a separate mixer is not really required.

|-
| 05:54
|It also has a port to connect an '''energy stream'''.

|-
| 05:59
|As we can see now

|-
| 06:02
|These ideas will be taken up in the assignment section.

|-
| 06:07
| Let us connect the '''Vapour '''stream to the '''Vapour outlet''' port.

|-
| 06:13
| Similarly, connect the '''Liquid''' stream.

|-
| 06:21
|Once again, we can move the items for better alignment.

|-
| 06:26
| Notice that '''DWSIM''' completed the calculations automatically.

|-
| 06:31
|You are free to press the '''Recalculate''' button also.

|-
| 06:35
|In fact you should do this whenever you are in doubt.

|-
| 06:39
| We now check whether the vapor and liquid are split properly in the separator.

|-
| 06:45
| Let us look at the vapor phase mole fractions of the stream '''Vapour.'''

|-
| 06:52
|The mole fraction of '''Benzene''' is '''0.54.'''

|-
| 06:56
| Let us check whether this is in agreement with what '''mixer-out''' has.

|-
| 07:04
|You can see that '''DWSIM '''automatically displays '''vapor''' value. The '''benzene mole fraction''' is 0.54.

|-
| 07:13
|This is an indirect evidence that the '''Separator''' is working as expected.

|-
| 07:18
|We can do a check on the working of the '''Mixer '''also'''.'''

|-
| 07:22
|You can see the '''Mixture''' composition is equimolar, as expected.

|-
| 07:29
| We will postpone a few other checks to the Assignment Section.

|-
| 07:34
| Let us save this file using the '''save as''' option.

|-
| 07:39
| I will save it as '''flow-end.'''

|-
|07:46
|I suggest that you keep saving your work frequently.

|-
| 07:49
| Let me summarise.

|-
| 07:52
| We defined a simple flowsheet.

|-
| 07:54
|Explained how to create mixed feed.

|-
| 07:58
|Introduced '''mixer''' and '''separator.'''

|-
| 08:00
|Showed how to connect them.

|-
| 08:02
|Explained how to simulate.

|-
| 08:04
| Let me give some assignments.

|-
| 08:07
| The assignment in this slide has to do with mass balances.

|-
| 08:10
|I use blue colour to indicate streams and equipment.

|-
| 08:15
| Let us go to the next Assignment.

|-
| 08:16
| You have to verify mole fractions as mentioned in this slide.

|-
| 08:20
| The third assignment has to do with the '''Separator.'''

|-
| 08:25
|Recall that we mentioned that it could be used to mix streams.

|-
| 08:30
|Remove the '''mixer''' and '''mixer-out''' and try it out.

|-
| 08:35
| In the next assignment, you will do the separation at a higher temperature.

|-
| 08:41
| Click on '''Separator.'''Lets scroll up.

|-
| 08:46
| Let us change '''Override separation temperature''' to true.

|-
| 08:52
| In the resulting field, change the value to '''100.'''

|-
| 08:59
| Bring '''Energy stream''' from '''Object Palette''' to the Flowsheet. This is a new stream.

|-
| 09:07
|Connect this stream to the '''Energy Stream''' of the '''Separator''' that I showed earlier.

|-
| 09:13
|Simulate and analyse your results.

|-
| 09:16
|This is summarised in the slide here.

|-
| 09:22
