|-
||00:01
|| Welcome to this tutorial on '''Introduction to flowsheeting''' in '''DWSIM'''
|-
|| 00:07
|| In this tutorial, we will learn to:

|-
|| 00:10
|| Simulate a '''mixer'''

|-
|| 00:12
|| Follow it up with a '''flash separator'''

|-
|| 00:15
|| Give a '''two phase feed '''
|-
|| 00:17
|| This tutorial is recorded using

'''DWSIM version 5. 8 (Classic UI) Update 3 '''and '''Windows 10 OS'''

|-
|| 00:27
|| But, this process is identical in '''Linux, Mac OS X '''or '''FOSSEE OS on ARM'''.
|-
|| 00:35
|| To practice this tutorial, you should have an introductory exposure to '''DWSIM'''.

|-
|| 00:41
|| The prerequisite '''DWSIM '''tutorials are mentioned on our website.
|-
|| 00:47
|| '''flow-begin''' file used in the tutorial is provided as a '''Code file''' on this tutorial page.

|-
|| 00:54
|| Download the file from '''Code Files''' link.
|-
||00:58
|| I have already opened '''DWSIM''' on my machine.
|-
||01:02
|| Please ensure that '''DWSIM''' opens as an '''administrator'''.
|-
|| 01:07
|| Go to '''File''' menu and click on '''Open File'''.
|-
|| 01:12
|| I have already downloaded and extracted the '''flow-begin''' file on my '''Desktop'''.

|-
|| 01:18
|| Select the file from the '''Desktop'''.

|-
|| 01:22
|| This file already contains all the '''material streams''' necessary for this tutorial.
|-
|| 01:28
|| You can see two streams '''Inlet1''' and '''Inlet2''' in the '''flowsheet''' canvas.
|-
||01:34
|| Let us go back to the slides.
|-
|| 01:37
|| It summarises the contents of this file.

|-
|| 01:41
|| When we mix these '''streams''', we get '''equimolar composition.'''
|-
||01:46
|| Let us go back to '''DWSIM'''.
|-
|| 01:49
|| We will now modify the '''streams''', so as to have vapor in them.

Select '''Inlet 1'''.
|-
|| 01:57
|| On the left, go to the '''Property Editor Window.'''
|-
|| 02:01
|| Go to '''Input Data.'''

|-
|| 02:03
|| Under '''Stream Conditions '''tab, select '''Flash Spec''' as''' Pressure and Vapor Fraction.''' '''(PVF)'''
|-
|| 02:11
|| Type '''Vapor Phase Mole Fraction '''as '''1''' and press '''Enter.'''

Here the entire '''stream''' is a '''vapor'''.
|-
|| 02:21
|| In a similar way, make '''Inlet2''' to have '''50% vapor fraction. '''
|-
|| 02:27
|| Select '''Inlet 2'''.
|-
|| 02:30
|| Under '''Stream Conditions '''tab, select '''Flash Spec''' as''' Pressure and Vapor Fraction.''' '''(PVF)'''
|-
|| 02:39
|| Type '''Vapor Phase Mole Fraction '''as '''0.5''' and press '''Enter'''.
|-
|| 02:45
|| Now let us insert a '''mixer''' to the '''flowsheet'''.
|-
|| 02:49
|| At the bottom of the main '''simulation''' window, go to '''Mixers/Splitters.'''
|-
|| 02:55
|| From the displayed list, drag and drop a '''Stream Mixer '''to the '''Flowsheet'''
|-
|| 03:00
|| Click on the '''mixer''' named '''MIX 002.'''
|-
|| 03:05
|| Let's change the name of '''MIX 002''' to '''Mixer.'''

Press '''Enter'''.
|-
|| 03:10
|| Now let us insert an '''output stream''' for the '''mixer'''.
|-
||03:14
|| Click on '''Streams '''tab.

From the displayed list, drag and drop a '''Material Stream '''to the '''Flowsheet'''.
|-
| 03:21
|| We will leave that '''stream''' as unspecified.
|-
||03:24
|| Let’s change the name of this '''stream''' to '''mixer-out.'''

Press '''Enter'''.
|-
|| 03:31
|| We are now ready to specify the '''Mixer.'''

So let’s click on it.
|-
||03:36
|| On the left, we can see a tab displaying properties related to the '''Mixer.'''
|-
|| 03:42
|| Here we can see that the '''mixer''' has up to 6 '''inlet streams'''.
|-
|| 03:48
|| Under '''Connections,''' click on the drop-down against '''Inlet Stream 1.'''

Select '''Inlet1.'''
|-
|| 03:57
|| Click on the drop down against '''Inlet Stream 2''' and select '''Inlet2.'''
|-
|| 04:04
|| Click on the drop down against '''Outlet Stream '''and select '''mixer-out.'''
|-
||04:11
|| We can move the '''streams''' to make them better aligned.
|-
|| 04:15
|| The '''mixer''' is red, as it is not '''simulated''' yet.
|-
|| 04:19
|| Click on the '''mixer'''.
|-
|| 04:22
|| Go to '''Calculation Parameters'''.

|-
|| 04:25
|| Click on the drop-down against '''Pressure Calculation'''.
|-
|| 04:30
|| We can see there are three different modes of''' Pressure Calculation''':

'''Inlet Minimum''', '''Inlet Average''', '''Inlet Maximum'''
|-
|| 04:40
|| Select '''Inlet Minimum''' if '''outlet pressure''' has to be minimum of all''' inlet streams'''.
|-
|| 04:47
|| Select '''Inlet Average''' if '''outlet pressure''' has to be average of all '''inlet streams'''.
|-
|| 04:53
|| Select '''Inlet Maximum '''if '''outlet pressure''' has to be maximum of all '''inlet streams'''.
|-
|| 05:00
|| Here both the '''inlet streams''' are at''' 1 atmosphere pressure.'''

|-
|| 05:06
|| So, the '''Pressure Calculation''' mode will not matter here.

|-
|| 05:10
|| By default, '''Inlet Minimum''' is selected, we will leave it unchanged.
|-
||05:16
|| Now we will run the '''simulation.'''
|-
|| 05:19
|| So, click on the '''Solve Flowsheet''' button on the toolbar.
|-
|| 05:24
|| The '''mixer''' has become blue now.

|-
|| 05:27
|| It means that the calculations are completed.
|-
|| 05:31
|| Now click on '''mixer out''' stream.

|-
|| 05:34
|| Go to the '''Property Editor Window''' of the '''Mixer.'''

|-
|| 05:38
|| Locate '''Results''' tab.
|-
|| 05:41
|| Navigate to '''Compounds Amounts Mixture.'''
|-
|| 05:47
|| We can verify that its composition is as expected.

|-
|| 05:52
|| It has '''equimolar composition. '''
|-
||05:56
|| Now let us insert a '''Gas-Liquid Separator'''.
|-
|| 06:00
|| It can be used to '''simulate VLE, LLE '''and''' VLLE''' systems.
|-
|| 06:06
|| At the bottom of the main '''simulation''' window, go to '''Separators/Tanks'''.

|-
|| 06:12
|| From the displayed list, drag and drop a '''Gas-Liquid Separator '''to the '''Flowsheet'''.
|-
|| 06:18
|| Click on the '''Gas-Liquid Separator''' named '''SEP-004.'''
|-
|| 06:24
|| Now we will connect two '''output streams''' to the '''Separator'''.
|-
|| 06:29
|| Drag and drop a '''Material Stream''' to the '''flowsheet''' area.

|-
|| 06:33
|| We will leave that '''stream''' as unspecified, as its properties are to be calculated.
|-
|| 06:40
|| We will name it as '''Vapour'''.
|-
|| 06:43
|| Similarly, add another '''material stream''' and name it as '''Liquid.'''
|-
|| 06:49
|| We are now ready to specify the '''Gas-Liquid Separator.'''

So let’s click on it.
|-
|| 06:56
|| On the left, we can see a tab displaying properties related to the '''Gas-Liquid Separator.'''
|-
||07:03
|| Under '''Connections,''' click on the drop-down against '''Inlet Stream 1'''.

Select '''mixer-out.'''
|-
|| 07:12
|| We can now connect a total of five more''' input streams. '''

|-
|| 07:16
|| The '''Separator '''mixes all the '''streams''' and separates.
|-
|| 07:21
|| It also has a '''port''' to connect an '''Energy Stream'''.
|-
|| 07:25
|| Click on the drop-down against '''Vapour Stream''' and select '''Vapour.'''
|-
|| 07:31
|| Similarly, click on the drop-down against '''Light Liquid Stream'''.

Select '''Liquid.'''
|-
|| 07:39
||Then click on '''Solve Flowsheet''' button on the toolbar.
|-
||07:43
|| Now we will check whether the vapor and liquid are split properly in the '''separator'''.
|-
|| 07:50
|| Now click on '''Vapour stream.'''

|-
|| 07:53
|| From the '''Property Editor Window''', locate '''Results''' section.
|-
|| 07:58
|| Navigate to '''Compounds Amounts Mixture.'''
|-
|| 08:03
|| The '''mole fraction''' of '''Benzene''' is '''0.55.'''
|-
||08:08
|| We can do a check on the working of the '''Mixer '''also'''.

|-
|| 08:12
|| Now click on '''mixer-out'''.

From the '''Property Editor Window''', locate '''Results''' section.
|-
|| 08:20
|| Navigate to '''Compounds Amounts Vapor.'''
|-
|| 08:26
|| The '''mole fraction''' of '''Benzene''' is '''0.55.'''
|-
|| 08:30
|| Let us now save this file using the '''Save As''' option.
|-
|| 08:35
|| I will save it as '''flow end.'''
|-
||08:40
||Let's summarise.
|-
|| 08:41
|| In this tutorial, we have learnt to

Simulate a '''mixer''', Follow it up with a '''flash separator''' and Give a '''two phase feed '''
|-
||08:50
|| Here are some assignments for you.
|-
||08:53
|| The assignment in this slide has to do with''' mass balances. '''

|-
|| 08:57
|| I use blue colour to indicate '''streams''' and equipment.
|-
||09:02
|| Let us go to the next assignment.
|-
||09:06
|| You have to verify '''mole fractions''' as mentioned in this slide.
|-
||09:10
|| The third assignment has to do with the '''Separator.'''

|-
|| 09:14
|| Recall that we mentioned that it could be used to mix '''streams'''.

|-
|| 09:19
|| Remove the '''mixer''' and '''mixer-out''' and try it out.

|-
|| 09:23
|| See if you get the same answers.
|-
||09:27
||In the next assignment, you will do the separation at a higher temperature.
