|-
|| 00:01
|| Welcome to this tutorial on simulating a '''Continuous Stirred Tank Reactor (CSTR)''' in '''DWSIM'''.

|-
|| 00:07
|| In this tutorial, we will learn to: Simulate a '''Continuous Stirred Tank Reactor (CSTR)'''

|-
|| 00:14
|| Calculate '''Conversion''' and '''Residence Time''' for a '''reaction''' in a '''CSTR'''

|-
||00:20
|| To record this tutorial, I am using '''DWSIM 4.3''' and '''Windows 7'''

|-
|| 00:28
||The process demonstrated in this tutorial is identical in other OS also such as- '''Linux''', '''Mac OS X''' or '''FOSSEE OS''' on '''ARM'''.

|-
|| 00:40
|| To practice this tutorial, you should know how to- add components to a '''flowsheet.'''

|-
|| 00:46
|| Select '''thermodynamic''' packages.

|-
|| 00:49
|| Add '''material''' and '''energy''' stream and specify their properties.

|-
|| 00:54
|| And add '''kinetic reaction''' in '''reaction manager.'''

|-
|| 00:58
|| The pre-requisite tutorials are mentioned on our website

|-
|| 01:03
||You can access these tutorials and all the associated files from this site.

|-
|| 01:09
|| We will develop a '''flowsheet''' to determine the '''exit composition '''from an '''isothermal CSTR.'''

|-
|| 01:16
||Here we give '''Reaction, Property Package '''and''' Inlet Stream Conditions.'''

|-
|| 01:22
|| Next, we give '''CSTR dimensions''' and '''reaction kinetics'''.

|-
||01:27
|| I have already opened '''DWSIM''' on my machine.

|-
|| 01:32
||Go to '''File''' menu and select '''New Steady-state Simulation.'''

|-
|| 01:37
||'''Simulation Configuration Wizard''' window appears. At the bottom, click on '''Next'''.

|| Then click on '''Finish.'''

|-
|| 02:46
|| Let us now maximize the simulation window.

|-
|| 02:50
|| Let’s insert a '''feed stream''' that enters the '''CSTR'''.

|-
|| 02:54
|| Go to '''Object Palette'''.

|-
|| 02:56
|| From '''Streams''' section, drag and drop a '''Material Stream''' to the '''Flowsheet'''.

|-
|| 03:02
|| Let’s change the name of this stream to''' Feed.'''

|-
|| 03:07
|| Now we will specify the '''Feed''' stream properties.

|-
||03:12
|| Go to '''Input Data.'''

|-
|| 03:15
||Select '''Flash Spec''' as '''Temperature and Pressure (TP),''' if not already selected.

|-
|| 03:33
|| Change '''Pressure''' to '''1 bar''' and press '''Enter.'''

|-
|| 03:38
|| Change '''Mass Flow''' to '''3600 kg/hour''' and press '''Enter.'''

|-
|| 03:45
|| Now let us specify the '''feed stream compositions.'''

|-
|| 03:50
|| Under '''Composition''', choose the '''Basis''' as '''Mole Fractions''', if not already selected.

|-
|| 03:57
||By default, '''Mole Fractions''' is already selected as '''Basis.'''

|-
||04:02

|-
|| 05:21
|| First column '''Name''' shows the available compounds here.

|-
|| 05:26
|| Second column corresponds to its '''Molar Weight'''

|-
|| 05:30
|| Next column is '''Include.''' Under '''Include''', check all the check boxes.

|-
|| 05:37
|| The fourth column is '''BC.''' Under '''BC''', check the '''Ethanol''' check box as '''Ethanol''' is the '''base component'''.

|-
|| 05:47
|| Next column is '''Stoichiometric coefficients'''

|-
|| 05:51
|| Under ''' Stoichiometric coefficients '''column, enter: '''-1''' for '''Ethanol'''

|-
||05:58
|| '''-1''' for '''Acetic Acid'''

|-
||06:01
|| '''1''' for '''Water''' and '''1''' for '''Ethyl Acetate''' and then press '''Enter.'''

|-
||06:10
|| In the '''Stoichiometry '''field, we can see it is showing '''OK'''.

|-
|| 06:15
|| Here the '''Equation''' field shows the '''reaction equation'''.

|-
||06:20
|| Next column is '''DO.'''

|-
|| 06:22
|| We are considering the reaction to be elementary.

|-
||06:26
|| So under '''DO''' column, enter: '''1''' for '''Ethanol'''

|-
||06:32
|| '''1''' for '''Acetic Acid'''. And then press '''Enter.'''

|-
|| 06:38
|| Next column is '''RO.'''

|-
||06:41
|| Since we are considering an irreversible reaction, we will not enter anything here.

|-
|| 06:47
|| Then comes '''Kinetic Reactions Parameters.'''

|-
|| 06:51
|| Our rate is in terms of '''molar concentration'''.

|-
||06:55
|| So we will select '''Basis''' as '''Molar Concentrations.'''

|-
||07:00

|| And then let us insert one '''Output Stream.'''

|-
|| 07:54
|| To do that let us drag one '''Material Stream.'''

|-
|| 07:58
|| Let us once again arrange it.

|-
|| 08:01
|| Leave that stream as unspecified.

|-
|| 08:04
|| We will change the name of this '''stream''' to '''Product.'''

|-
|| 08:09
|| Next, we will insert one '''Energy Stream.''' And name this '''stream''' as '''Energy.'''

|-
|| 08:16
|| We are now ready to specify the''' Continuous Stirred Tank Reactor.'''
