| | Welcome to this tutorial on simulating an '''Equilibrium Reactor '''in '''DWSIM.'''

|-
| | 00:07
| | In this tutorial, we will learn to:

|-
| | 00:10
| |Define an '''Equilibrium Reaction'''

|-
| | 00:13
| | Simulate an''' Equilibrium Reactor'''

|-
| | 00:16
| | Calculate '''Conversion percentage''' and '''Reaction Extent'''

|-
| | 00:20
| | To record this tutorial, I am using

|-
| | 00:23
| | '''DWSIM 5.2''' '''(Classic UI) update 22''' and '''Windows 10'''

|-
| | 00:30
| |The process demonstrated in this tutorial is identical in other OS also such as-

'''Linux''', '''Mac OS X''' or '''FOSSEE OS''' on '''ARM'''.

|-
| |00:41
| | To practice this tutorial, you should know to-

Add components to a '''flowsheet.'''

|-
| | 00:47
| | select '''thermodynamic''' packages.

|-
| | 00:50
| | add '''material''' and '''energy''' streams and specify their properties.

|-
| | 00:56
| | The prerequisite tutorials are mentioned on our website.

|-
| | 01:01
| |You can access these tutorials and all the associated files from this site.

|-
| | 01:07
| | We will develop a '''flowsheet''' to determine the '''exit composition '''from an '''Equilibrium Reactor.'''

|-
| | 01:14
| |Here we give '''Reaction '''and''' Inlet Stream Conditions'''.

|-
| | 01:19
| | Here we give '''Property Package''' and '''Reaction Temperature.'''

|-
| | 01:24
| | I have already opened '''DWSIM''' on my machine.

|-
| | 01:28
| |Go to '''File''' menu and select '''New Steady-state Simulation.'''

|-
| | 01:35
| | '''Simulation Configuration Wizard''' window appears.

|-
| | 01:39
| | Click on '''Next '''button at the bottom.

|-
| | 01:43
| | In the '''Compounds search''' tab, type '''Carbon monoxide.'''

|-
| | 01:48
| |Select '''Carbon monoxide '''from the '''ChemSep '''database.

|-
| | 01:52
| | Similarly, add '''Water.'''

|-
| |01:56
| | Similarly, add '''Hydrogen.'''

|-
| | 02:00
| | Next, add '''Carbon Dioxide.'''

|-
| | 02:04
| | And then at the bottom, click on the '''Next '''button.

|-
| | 02:09
| | The '''Property Packages '''opens.

|-
| | 02:12
| | From '''Available Property Packages''' list, double-click on '''Raoult’s Law.'''

|-
| | 02:18
| | Then click on the '''Next '''button.

|-
| | 02:22
| | We will be moved to a new window named '''Flash Algorithm'''.

|-
| | 02:27
| | From '''Default Flash Algorithm, '''select '''Nested Loops(VLE).'''

|-
| | 02:33
| | Click on the '''Next '''button.

|-
| | 02:36
| | The next option is '''System of Units.'''

|-
| |02:40
| | Under '''System of Units, '''we will select '''C5'''.

|-
| | 02:46
| | Then at the bottom, click on the '''Finish '''button.

|-
| | 02:51
| | Let us now maximize the simulation window.

|-
| | 02:55
| | Now let’s insert a '''feed stream''' that enters the '''Equilibrium Reactor'''.

|-
| | 03:00
| | On the right hand side of the main simulation window, go to '''Flowsheet Objects.'''

|-
| | 03:06
| | In the '''Filter List '''tab, type '''Material Stream.'''

|-
| | 03:11
| | From the displayed list, drag and drop a '''Material Stream '''to the '''Flowsheet'''.

|-
| | 03:17
| | Let’s change the name of this '''stream''' to '''Feed.'''

|-
| | 03:21
| | Now we will specify the '''Feed stream''' properties.

|-
| | 03:26
| | Go to '''Input Data.'''

|-
| | 03:29
| |Under '''Stream Conditions '''tab, select '''Flash Spec''' as '''Temperature and Pressure (TP),''' if not already selected.

|-
| | 03:38
| | By default, '''Temperature '''and''' Pressure '''are already selected as '''Flash Spec.'''

|-
| | 03:44
| | Change '''Temperature''' to '''25 degree Centigrade''' and press '''Enter.'''

|-
| | 03:40
| | Change '''Pressure''' to '''1.01325 bar''' and press '''Enter.'''

|-
| | 03:58
| | Change '''Mass Flow''' to '''3600 kg per hour''' and press '''Enter.'''

|-
| | 04:05
| | Now let us specify the '''feed stream compositions.'''

|-
| | 04:10
| |Under '''Input Data, '''click on '''Compound Amounts''' tab.

|-
| | 04:15
| | Choose the '''Basis''' as '''Mole Fractions''', if not already selected.

|-
| | 04:20
| |By default, '''Mole Fractions''' is selected as '''Basis.'''

|-
| | 04:25
| | Now for '''Carbon monoxide''', enter the '''Amount''' as '''0.5''' and press '''Enter.'''

|-
| | 04:33
| | For '''Water, '''type '''0.5''' and press '''Enter'''.

|-
| |04:38
| | For '''Hydrogen, '''type '''0''' and press '''Enter'''.

|-
| | 04:43
| | Similarly, for '''Carbon dioxide''', type '''0''' and press '''Enter'''.

|-
| | 04:50
| | At the bottom, click on '''Commit New Values ''' button.

|-
| | 04:56
| | Next, we will define the '''Equilibrium Reaction.'''

|-
| | 04:59
| | Under '''Tools''', click on '''Reactions Manager.'''

|-
| | 05:04
| |'''Chemical Reactions Manager''' window opens.

|-
| | 05:08
| | Under '''Chemical Reactions''' tab, click on the green coloured '''Add Reaction''' button.

|-
| | 05:15
| | Then click on '''Equilibrium.'''

|-
| | 05:18
| | '''Add New Equilibrium Reaction''' window opens.

|-
| | 05:22
| | Under '''Identification''', enter the '''Name''' as '''Water Gas Shift Reaction.'''

|-
| | 05:29
| | Let’s enter the '''Description.'''

“'''Reaction of carbon monoxide and water vapor to form carbon dioxide and hydrogen.”'''

|-
| | 05:40
| | Next part is the table of '''Components and Stoichiometry.'''

|-
| | 05:45
| | The first column '''Name''' shows the available components here.

|-
| | 05:50
| | The second column corresponds to its '''Molar Weight.'''

|-
| | 05:54
| | The next column is '''Include.''' Under '''Include''', check all the check boxes.

|-
| | 06:02
| | The fourth column is '''BC.''' Under '''BC''', check the '''Carbon monoxide''' check box as conversion is defined in terms of '''Carbon monoxide'''.

|-
| | 06:14
| | Next column is '''Stoichiometric Coefficients'''

|-
| | 06:18
| | Under '''Stoichiometric Coefficients''' column, enter:

'''-1''' for '''Carbon monoxide'''

|-
| | 06:25
| | '''-1''' for '''Water'''

|-
| | 06:28
| | '''1''' for '''Hydrogen '''and

|-
| | 06:31
| | '''1''' for '''Carbon dioxide'''

Then press '''Enter.'''

|-
| | 06:36
| | In the '''Stoichiometry '''field, we can see it shows '''OK'''.

|-
| | 06:41
| | It means the reaction is balanced after entering the '''stoichiometric''' '''coefficients'''.

|-
| | 06:47
| | Here the '''Equation''' field shows the '''reaction equation'''.

|-
| | 06:51
| | Then comes '''Equilibrium Reactions Parameters.'''

|-
| | 06:55
| | The '''Basis''' is already selected as '''fugacity'''.

|-
| | 06:59
| | Select '''Phase''' as '''Vapor.'''

|-
| | 07:03
| | Now, go to '''Equilibrium Constant .'''

|-
| | 07:07
| | In an '''Equilibrium Reaction''', the '''equilibrium constant''' can be defined in three different ways.

|-
| | 07:14
| | First is '''Gibbs Energy of Reaction.'''

|-
| | 07:18
| | If the '''equilibrium constant''' is unknown, it is calculated directly from '''Gibbs energy of reaction'''.

|-
| | 07:25
| | Second is '''T function'''.

|-
| | 07:28
| | Here the '''equilibrium constant''' can be defined as a function of temperature.

It is in the form of '''ln Keq f of T.'''

|-
| | 07:39
| | Third is '''Constant value''' where the equilibrium constant is defined directly.

|-
| | 07:45
| | Here, we don't know the '''equilibrium constant '''directly or as a function of temperature.

|-
| | 07:52
| | So, we will let it calculate from the '''Gibbs energy of reaction'''.

Select '''Calculate from Gibbs Energy of Reaction.'''

|-
| | 08:02
| | Click on '''OK''' at the bottom.

And then close the '''Chemical Reactions Manager''' window.

|-
| | 08:09
| | Now let us insert an '''Equilibrium Reactor''' to the '''flowsheet'''.

|-
| | 08:14
| | Go to '''Flowsheet Objects.'''

|-
| | 08:17
| | In the '''Filter List''' tab, type''' Equilibrium Reactor.'''

|-
| | 08:22
| | Drag and drop '''Equilibrium Reactor''' to the '''flowsheet.'''

|-
| | 08:26
| | Let us arrange it as required.

|-
| | 08:29
| | Next, name the '''reactor '''as '''Equilibrium Reactor.'''

|-
| | 08:34
| | Now let’s insert two more '''material streams''' that exit the '''Equilibrium Reactor.'''

|-
| | 08:41
| | To do that, let us drag one '''Material Stream '''to the '''flowsheet'''.

|-
| | 08:47
| | Let us now arrange it.

|-
| | 08:50
| | We will leave that '''stream''' as unspecified.

|-
| | 08:54
| | Then we will change the name of this '''stream '''to '''Vapour Product.'''

|-
| | 09:00
| | Next, we will insert another '''Material Stream.'''

|-
| | 09:04
| | Let us once again arrange it.

|-
| | 09:07
| | Leave that '''stream''' as unspecified.

|-
| | 09:10
| | And name this '''stream '''as '''Liquid Product.'''

|-
| | 09:14
| | Next, we will insert one '''Energy Stream.'''

|-
| | 09:20
| | And name this '''stream''' as '''Energy.'''

|-
| | 09:24
| | We are now ready to specify the '''Equilibrium Reactor.'''

So let’s click on it.

|-
| | 09:31
| | On the left, we can see a tab displaying properties related to the '''Equilibrium Reactor.'''

|-
| | 09:38
| | Under '''Connections,''' click on the drop-down against '''Inlet Stream.'''

And select '''Feed.'''

|-
| | 09:46
| | Next, click on the drop-down against '''Outlet Stream 1''' and select '''Vapour Product.'''

|-
| | 09:54
| | Next, click on the drop-down against '''Outlet Stream 2''' and select '''Liquid Product.'''

|-
| | 10:02
| |Next click on the drop-down against '''Energy Stream''' and select '''Energy.'''

|-
| | 10:10
| | Now we will go to the next section, '''Calculation Parameters.'''

|-
| | 10:16
| | Here, the first option is '''Reaction Set.'''

|-
| | 10:21
| | This option is selected as '''Default Set'''.

|-
| | 10:25
| | Next, click on the drop-down against '''Calculation Mode.'''

|-
| | 10:30
| | Select '''Define Outlet Temperature.'''

|-
| | 10:34
| | Enter '''225 degree C''' against '''Outlet Temperature.'''

|-
| | 10:40
| | Now we will run the '''simulation.'''

|-
| | 10:43
| | So, click on '''Solve Flowsheet''' button on the toolbar.

|-
| | 10:48
| | Once the calculation are complete, click on the '''Equilibrium Reactor '''in the '''flowsheet'''.

|-
| | 10:54
| | Go to the '''Property Editor Window''' of the '''Equilibrium Reactor.'''

Locate '''Results''' section.

|-
| | 11:02
| | Under '''Reactions''' tab, check '''Extent.'''

It is '''20.043.'''

|-
| | 11:08
| | This is the extent of the water gas shift reaction at '''225 degree Centigrade'''.

|-
| | 11:14
| | Now go to the '''Conversions''' tab.

|-
| | 11:17
| | We will look into the individual conversions of all the '''reactants'''.

|-
| | 11:22
| | Here for '''Carbon monoxide,''' the conversion is '''92.2478%''' and for '''Water''' it is '''92.2478%.'''

|-
| | 11:34
| | Now, go to '''Insert''' menu and select '''Master Property Table.'''

|-
| | 11:40
| | Double-click on the '''Master Property Table.'''

|-
| | 11:44
| | '''Configure Master Property Table''' window opens.

|-
| | 11:48
| | Enter '''Name''' as '''Stream Wise Results Equilibrium Reactor.'''

|-
| | 11:54
| | Enter '''Object Type''' as '''Material Stream'''.

|-
| | 11:58
| | By default, '''Material Stream''' is already selected.

So we will not change it.

|-
| | 12:04
| | Under '''Properties to display''', select '''Object''' as '''Feed''', '''Vapour Product '''and '''Liquid Product.'''

|-
| | 12:14
| | Under '''Property, '''scroll down to see all the parameters.

|-
| | 12:20
| | Now select the properties as

'''Temperature''', '''Pressure''', '''Mass Flow''' , '''Molar Flow'''

|-
| | 12:32
| | '''Molar Flow (Mixture) / Carbon monoxide'''

|-
| | 12:36
| | '''Mass Flow (Mixture) / Carbon monoxide'''

|-
| | 12:40
| | '''Molar Flow (Mixture) / Water'''

|-
| | 12:43
| | '''Mass Flow (Mixture) / Water'''

|-
| | 12:46
| | '''Molar Flow (Mixture) / Hydrogen'''

|-
| | 12:49
| | '''Mass Flow (Mixture) / Hydrogen'''

|-
| | 12:54
| | '''Molar Flow (Mixture) / Carbon dioxide'''

|-
| | 12:57
| | '''Mass Flow (Mixture) / Carbon dioxide'''

|-
| | 13:01
| | Let’s close this window.

|-
| | 13:04
| | Move the '''Master Property Table''' for better visibility.

|-
| | 13:10
| | Here we can see the corresponding results for '''Vapour Product''', '''Liquid Product''' and '''Feed.'''

|-
| | 13:17
| | The reaction is a '''Vapour Phase''' reaction.

|-
| | 13:21
| | So, we can see that '''Liquid Product stream''' shows zero flow rate and composition.

|-
| | 13:28
| | Let's summarize.

|-
| | 13:30
| | In this tutorial, we have learnt to

Define an '''Equilibrium Reaction''', Simulate an''' Equilibrium Reactor''', Calculate '''Conversion percentage''' and '''Reaction extent'''
