|| Welcome to this tutorial on '''Creating Reaction Set with Multiple Reactions''' in '''DWSIM'''.
|- 
|| 00:09
|| In this tutorial, we will learn to:

|- 
|| 00:12
|| Create '''Reaction Set''' with '''Multiple Reactions'''

|- 
|| 00:16
|| Copy and reuse a '''Conversion Reaction'''

|- 
|| 00:20
|| Use '''Create and Connect''' feature to auto create and connect '''Material Streams'''

|- 
|| 00:27
|| To record this tutorial, I am using

'''DWSIM 5.8 (Classic UI) Update 4''' and '''Windows 10 OS'''

|- 
|| 00:39
||The process demonstrated in this tutorial is identical in other OS also such as- '''Linux''', '''Mac OS X''' or  '''FOSSEE OS''' on '''ARM'''.
|- 
|| 00:51
|| To practice this tutorial, you should know to-

Add '''material''' and '''energy streams''' and specify their properties.

|- 
|| 01:00
|| Add '''Conversion Reaction'''
 
|- 
|| 01:03
||Specify '''Conversion Reactor''' parameters
|- 
|| 01:07
|| The prerequisite tutorials are mentioned on our website.
|- 
|| 01:12
||You can access these tutorials and all the associated files from this site.
|- 
|| 01:19
|| '''Multiple Reaction''' file used in the tutorial is provided as a '''Code file '''on this tutorial page.

|- 
|| 01:27
||Download the file from '''Code Files''' link. 

Make a copy and then use it while practising.
|- 
|| 01:36
|| We will develop a '''flowsheet''' to determine the '''exit composition '''from''' Conversion Reactor''' with '''multiple reactions.'''

|- 
|| 01:44
|| Here we give '''Property Package''' and '''Inlet Streams Conditions, '''as shown here'''.'''

|- 
|| 01:50
|| Next, we give the '''Reactions '''and '''Reaction Conversion''' for '''Reaction 1 '''and '''2'''.

|- 
||01:57
|| Here we give the '''Reaction inputs''' for '''Reaction 3 '''and '''4'''.

|- 
|| 02:03
|| Next, we give the '''Conversion Reactor''' operating conditions.
|- 
|| 02:09
|| The '''flowsheet''' to be created is shown here for ease of understanding.
|- 
||02:15

|- 
|| 07:21
|| This reaction is similar to the first reaction but with a different conversion.
|- 
|| 07:27
|| For this, we will not add a new reaction. 

We will copy the existing '''Reaction-1''' and edit the required fields.
|- 
|| 07:37
|| Select '''Reaction 1''' and click on '''Copy Selected Reaction''' button.
|- 
|| 07:43
|| We see that a new '''reaction''' is added named '''Reaction 11.'''

|| Under '''Connections''', click on the drop-down against '''Inlet Stream''' and select '''S-01'''.
|- 
|| 10:49
|| Now, click on yellow coloured '''Create and Connect''' button against '''Outlet Stream 1'''.

|- 
|| 11:49
|| Click on '''MSTR-003''' and rename as '''Null-01'''.
|- 
|| 11:55

|| 12:34
|| Next, click on drop-down against '''Inlet Stream 2''' and select '''S-02'''.
|- 
|| 12:42
|| Now click on '''Create and Connect''' button against '''Outlet Stream'''.

|- 
|| 12:48
|| A '''material stream''' gets created and connected to the '''Outlet Stream''' of '''MIX-01'''.
|- 
|| 12:55
|| Now, let us arrange the '''streams''' properly.
|- 
|| 12:59
|| Click on '''MSTR-007''' and rename as '''S 04'''.
|- 
|| 13:05
|| Now, let us finish creating the '''flowsheet'''.
|- 
|| 13:09

|- 
|| 14:10
|| Now, click on '''MSTR-009''' and rename it as '''Null-02'''.
|- 
|| 14:17
|| Click on '''MSTR 010''' and rename it as '''S 05'''.
|- 
|| 14:24
|| Click on '''ESTR-011''' and rename it as '''E 02'''.
|- 
|| 14:30
|| This completes the '''flowsheet'''.

|| Here for '''Ethylene''', the '''mass flow rate''' is '''0.001 kg/second ''', for '''Benzene''', it is '''20.903 kg/second'''.

|- 
|| 15:20
|| For '''Ethylbenzene''' it is '''20.252 kg/second''' and for '''P-diethylbenzene''' it is '''13.842 kg/s'''.
