|| Welcome to this tutorial on simulating a '''Chemsep Distillation Column''' in '''DWSIM.'''

|-
|| 00:08
|| In this tutorial, we will learn to

Specify properties of a '''Chemsep '''column and

|-
|| 00:14
|| Simulate a '''Distillation''' column
|-
|| 00:17
|| To record this tutorial, I am using 

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

|-
|| 00:28
||But, this process is identical in '''Linux, Mac OS X '''or '''FOSSEE OS on ARM'''.

|-
||00:36
|| To practice this tutorial, you should know to-

|-
|| 00:39
||Add components to a '''flowsheet'''

|-
|| 00:42
||Select '''thermodynamic packages'''

|-
|| 00:45
||Add '''material''' and '''energy streams''' and specify their properties. 
|-
|| 00:51
|| The prerequisite tutorials are available on this website.

|-
|| 00:56
||You can access these tutorials and all the associated files from this site.

|-
|| 01:02
|| '''DWSIM-Chemsep''' file used in the tutorial is provided as a '''Code file''' on this tutorial page. 

|-
|| 01:11
||Download the file from '''Code Files''' link. 
|-
|| 01:15
|| We will develop a '''flowsheet''' to determine '''Outlet stream''' properties after '''Distillation'''.

|-
|| 01:21
||Here we give '''Compounds''', '''Thermodynamics '''and '''Inlet stream conditions'''.
|-
|| 01:27
|| I have taken this problem statement from a paper published in '''Chemical Engineering Science'''.

For reference, I am citing the paper here.

|-
|| 01:37
|| I have already opened '''DWSIM''' on my machine. 

|-
|| 01:41
|| Go to '''File''' menu and click on '''Open File'''. 

|-
|| 01:46
| | I have already downloaded and extracted the file on my '''Desktop'''. 

Select the file from the '''Desktop'''. 

|-
|| 01:55
|| Let us maximize the '''simulation''' window. 

|-
|| 01:58
|| This file contains all '''material''' and '''energy streams''' necessary for this tutorial.

|-
| | 02:05
| | Now let us insert a '''Distillation Column '''into the '''flowsheet'''. 

|-
|| 02:09
|| At the bottom of the main '''simulation''' window, go to '''CAPE-OPEN '''tab.

|-
|| 02:15
|| Click on the '''CAPE-OPEN Unit Operation '''displayed. 

Drag and drop it to the '''flowsheet.''' 

|-
| | 02:21
| | '''Add CAPE-OPEN Unit Operation''' window opens. 

|-
| | 02:24
| | Select '''ChemSep''' from the displayed list of '''Unit Operations.''' 

|-
|| 02:30
||This list may vary depending on '''CAPE-OPEN Unit Operations''' that have been installed in your system.

|-
|| 02:37
||At the bottom, click on the '''Ok '''button'''.''' 

|-
| | 02:41
|| Let us now arrange it as required.

|-
|| 02:44
|| Click on the added '''CAPE-OPEN Unit Operation (COUO 005)''' 

|-
|| 02:49
| | We will change the name of the object to '''Distillation Column.''' 

|-
| | 02:54
| | First, we will connect the '''inlet feed streams'''.

|-
| | 02:57
|| Click on the''' Distillation Column'''.

|-
|| 02:59
||Go to the left side of the window.

|-
|| 03:01
||Under '''Connections''', go to the '''Inlet''' section.

|-
|| 03:06
||Click on the drop-down against '''feed''' and select '''Feed'''.

|-
|| 03:12
|| Click on '''Open CAPE-OPEN Object Editor''' button in the '''Object Property Editor''' window. 

|-
|| 03:17
|| '''New Unit Operation''' pop-up window appears. 

|-
| | 03:20
|| Click on the field against '''Unit Name '''and type '''Distillation Column.''' 

|-
|| 03:27
|| We will specify the rest of the details in a while.

|-
|| 03:31
||Click on the '''OK''' button at the bottom.

|-
|| 03:34
|| The '''ChemSep (CAPE-OPEN) -Distillation Column''' window will appear. 

|-
|| 03:39
|| Click on '''CAPE-OPEN''' on the left side of the '''ChemSep''' window. 

|-
|| 03:44
| | Under '''Distillation Column '''section, there is a checkbox against '''CAPE-OPEN Properties'''. 

|-
| | 03:51
| |This checkbox is checked by default.

|-
| | 03:55
| | This checkbox is to indicate if the column is to be '''simulated''' with

the '''CAPE-OPEN thermodynamics'''  or the native '''thermodynamics''' available with the column.

|-
|| 04:05
||We will use the native '''thermodynamics''' available with the column.

|-
|| 04:09
| | So we will uncheck the checkbox against '''CAPE-OPEN Properties'''.

|-
|| 04:15
| | Next, we have '''Expose energy ports'''. 

|-
|| 04:19
||This is to indicate if the '''energy connection ports''' are to be exposed to connect them to '''energy stream'''.

|-
|| 04:27
||This is needed if the '''energy streams''' are to be connected and used later for '''energy recycling'''. 

Else it can be unchecked.

|-
| | 04:37
| | For demonstration purposes, let us see how to connect the '''energy streams'''. 

|-
|| 04:42
||Therefore, check the '''Expose energy ports''' check-box.

|-
|| 04:47
| | Click on '''Save problem to file''' button on the toolbar.

|-
| | 04:52
|| Close the '''ChemSep''' window by clicking the cross button at the top right corner of the window. 

|-
| | 04:58
|| A pop-up appears, in which we will click '''Yes.'''

|-
| | 05:03
| | Now we will connect the '''outlet material streams''' with the column.

|-
|| 05:08
| | Click on the''' Distillation Column'''.

|-
| | 05:10
| |Go to the left side of the window.

Under '''Connections''', go to '''Outlet''' section.

|-
|| 05:17
||Then click on the drop-down against '''TopProduct''' and select''' Distillate'''.

|-
|| 05:25
| | Click on the drop-down against '''BottomProduct '''and select''' Bottoms'''.

|-
| | 05:32
| | Now we will connect the '''energy streams''' with the column.

|-
| | 05:36
| | Go to the '''Energy''' section.

Then click on the drop-down against '''Reboiler heat duty'''.

|-
| | 05:43
| |Select '''R-Duty.'''

|-
| | 05:46
|| Now click on the drop-down against '''Condenser heat duty.''' 

Select '''C-Duty.''' 

|-
|| 05:54
|| Now we will edit the properties of the '''Column'''. 

|-
|| 05:58
| | Click on '''Open CAPE-OPEN Object Editor''' button.

|-
| | 06:01
| | The '''ChemSep''' window opens. 

|-
| | 06:04
| | Click on '''Components''' on the left side of the '''ChemSep''' window.

|-
| | 06:08
|| We have already connected the '''feed streams''' to the column.

So the components are already listed here.

|-
| | 06:15
| | Click on '''Operation''' on the left side of the '''ChemSep''' window.

|-
|| 06:20
| | Under '''Select Type of Simulation''' section, '''Equilibrium column''' is selected by default.

|-
|| 06:26
||We are '''simulating''' a '''distillation''' column which is an '''equilibrium''' operation.

So we will leave it as it is.

|-
| | 06:34
| | Now we will move to '''Configuration''' section.

|-
|| 06:38
||Under '''Configuration,''' select '''Operation''' as '''Simple Distillation''', if not already selected.

|-
|| 06:44
||By default, '''Simple Distillation''' is already selected as '''Operation'''.

|-
| | 06:50
| | Select '''Condenser''' as '''Total Liquid Product''', if not already selected.

|-
|| 06:56
||By default, '''Total Liquid Product''' is already selected as '''Condenser'''.

|-
| | 07:01
| | Select '''Reboiler''' as '''Partial Liquid Product''', if not already selected.

|-
|| 07:06
||By default, '''Partial (Liquid Product)''' is already selected as '''Reboiler'''.

|-
|| 07:11
|| Next we will enter the '''Number of stages''' and '''Feed stage'''.

|-
|| 07:16
||Type the '''Number of stages''' as '''25''' and press '''Enter'''.

|-
|| 07:21
||A pop-up appears, in which we will click '''Yes.'''

|-
| | 07:26
| | Type the '''Feed stage''' as '''11 '''and press '''Enter.'''

|-
| | 07:30
| | Click on '''Properties''' on the left side of the '''ChemSep''' window. 

|-
| | 07:36
| | Here we will define the '''Thermodynamics''', '''Physical Properties''' and '''Reactions''' taking place in the '''column'''. 

|-
| | 07:42
| | First, we will define the '''Thermodynamics.''' 

|-
| | 07:46
| | Click on the drop-down against '''K-value'''.

Select '''DECHEMA'''.

|-
| | 07:53
| | Next, click on the drop-down against '''Activity coefficient''' and select '''UNIFAC'''.

|-
| | 08:01
| | Next, click on the drop-down against '''Vapour pressure''' and select '''Antoine'''.

|-
| | 08:08
|| Next, click on the drop-down against '''Enthalpy''' and select '''Ideal'''.

|-
|| 08:15
| | There are no '''Physical Properties''' or '''Reactions''' to be defined.

So, we will not specify them.

|-
| | 08:22
| | Now click on '''Feeds.'''

|-
|| 08:25
||The '''feed stream''' is already connected to the column.

|-
|| 08:29
||So the '''feed stream '''properties are already displayed here.

We will not change anything.

|-
| | 08:36
| | Now we will see how to define '''Pressure Profiles''' in '''Chemsep''' Column.

|-
|| 08:41
||Click on '''Pressures''' on the left side of the '''ChemSep''' window. 

|-
| | 08:46
| | Click on drop-down against '''Column pressure'''.

|-
|| 08:50
||Select the '''pressure profile''' to specify for the column depending on '''pressure data''' available.

By-default, '''Constant pressure''' is selected.

|-
|| 09:00
||We will not change that as the column is operated at constant pressure.

|-
|| 09:05
||Enter '''Condenser Pressure '''as '''101325 Newton per meter sqaure '''

|-
| | 09:13
| | Enter '''Top Pressure '''as '''101325  Newton per meter sqaure

|-
| | 09:20
| | Next click on '''Column Specs''' on the left side of the '''Chemsep''' window.

|-
| | 09:26
|| Go to '''Column Product Specifications''' section.

|-
|| 09:29
||Select the '''Top''' '''specification '''as '''Reflux ratio''', if not already selected.

|-
|| 09:35
||By default, '''Reflux Ratio''' is already selected as '''Specification.'''

|-
| | 09:40
|| Beside that we can see a value field.

Here we will enter '''Reflux Ratio''' as '''1.018''' and press '''Enter'''.

|-
| | 09:50
| | Now select the '''Bottom specification '''as '''mole fraction of a component''',

Enter the value as '''0.01''' and press '''Enter'''.

|-
|| 10:02
|| Below that, from the drop-down select''' Ethyl acetate'''.

|-
| | 10:07
| | Click on '''Save problem to file''' button on the toolbar.

|-
|| 10:11
| | Close the '''ChemSep''' window. 

|-
| | 10:14
| | Now we will run the '''simulation'''. 

|-
| | 10:16
|| To do this, click on '''Solve Flowsheet''' button on the toolbar.

|-
| | 10:21
|| When the calculations are completed, click on '''Distillate''' in the '''flowsheet'''.

|-
|| 10:27
||From the '''Property Editor window''', go to '''Input Data''' tab.

|-
|| 10:31
||Under '''Compounds Amounts''' tab, we can see that the '''Ethyl Acetate''' composition is '''0.999'''. 

|-
|| 10:40
