| 00:01
| Welcome to the spoken tutorial on Simulating a '''Shortcut distillation''' column in '''DWSIM.'''

|-
| 00:06
|I am Kannan Moudgalya

|-
| 00:08
| In this tutorial, we will simulate a '''Shortcut distillation''' column.

|-
| 00:13
|We will learn to calculate

'''Minimum number of stages '''

'''Minimum reflux ratio '''

'''Optimal Feed stage location '''

'''Condenser and reboiler duty '''

|-
| 00:23
|To achieve a particular product specification

|-
|00:26
| To record this tutorial, I am using '''DWSIM''' 3.4

|-
| 00:30
| To practice this tutorial you should know

|-
|00:32
|How to add components to a flowsheet

|-
| 00:35
|How to select '''thermodynamic''' packages

|-
| 00:37
|How to add material streams and specify their properties

|-
| 00:41
|The prerequisite tutorials are mentioned on our website, '''spoken-tutorial.org'''

|-
|00:47
| In the next two slides, we give specifications for the distillation problem.

|-
| 00:55
|This problem statement is given by Prof'''. Bill Luyben''' of '''Lehigh University.'''

|-
| 01:00
| I have already opened '''DWSIM.'''

|-
| 01:03
| Click on '''System of Units''' menu.

|-
| 01:07
|Select '''Custom 1.'''

|-
| 01:10
|This allows us to customise units, which we will do next.

|-
| 01:14
| Let us click on '''Configure Simulation''' button.

|-
| 01:18
| Add '''Benzene''' from the '''ChemSep''' Database

|-
|01:27
| Next '''Toluene'''

|-
| 01:33
| We will next click '''Thermodynamics''' and then '''Property Packages.'''

|-
| 01:40
| Scroll down and select '''Raoult’s Law'''.

|-
| 01:44
| Below the '''Thermodynamics '''option, you see '''Options '''menu. Click this.

|-
| 01:49
| Click '''Units System'''.

|-
| 01:53
| Let me bring this inside.

|-
| 01:56
| '''Pressure''' menu appears at the top of this list.

|-
| 01:58
| Click and choose '''atm''' for atmosphere.

|-
| 02:04
| Below the '''Pressure''' menu is the '''Molar flow rate''' menu.

|-
| 02:08
| Click it and select '''kmol/per hour'''.

|-
| 02:13
| Click on '''Back to simulation'''.

|-
| 02:15
| Let us insert a feed stream that has to be distilled.

|-
| 02:21
| Enter '''0.4''' for '''benzene''' and '''0.6''' for '''toluene.'''

|-
| 02:29
| '''Apply '''and '''Close'''.

|-
| 02:32
| We will change the name of this stream to '''Feed'''.

|-
| 02:39
| Click on '''Properties'''. Scroll to the top.

|-
| 02:43
| Click on '''Specification.'''

|-
| 02:46
| Choose '''Pressure and Vapor Fraction.'''

|-
| 02:50
| Locate the '''Molar flow rate '''option.

|-
| 02:53
| It has the units of '''kmol/per hour.'''

|-
| 02:57
| Click on this field. Enter '''100.'''

|-
| 03:02
| Locate '''Molar Fraction (Vapor Phase).'''

|-
| 03:08
| The default value is 0.

|-
| 03:10
| This indicates saturated liquid.

|-
|03:13
| Let us leave it as it is.

|-
| 03:16
| Let us insert a '''Shortcut column''' to the flowsheet.

|-
| 03:20
| Locate it from the '''Object palette'''.

|-
| 03:23
| The '''Shortcut Column''' is based on '''Fenske-Underwood-Gilliland''' method.

|-
| 03:27
| Click on it and drag it to the flowsheet.

|-
| 03:32
| Let us arrange it.

|-
| 03:34
| Now let us insert two '''output streams.'''

|-
| 03:37
| One will be '''distillate''' the other is '''Bottoms.'''

|-
| 03:41
| To do that let us drag two '''material streams.'''

|-
| 03:46
| As they are output streams, we will leave them unspecified.

|-
| 03:56
| We will change the name of these streams to '''Distillate''' and '''Bottoms.'''

|-
| 04:05
| Let us now insert two '''Energy streams.''' for '''Condenser duty '''and '''Reboiler duty.'''

|-
| 04:17
| Name these streams as '''C-Duty '''and '''R-Duty.'''

|-
| 04:24
| We are now ready to specify the '''Shortcut distillation column.'''

|-
| 04:27
| Click on it and select it.

|-
| 04:30
| Go to the '''Selected Object window.'''

|-
| 04:32
| Under the'''Properties '''tab, locate '''Connections''' menu.

|-
| 04:37
| The first option is '''Feed.'''

|-
| 04:38
| Let me click on '''Feed '''menu. A down arrow appears, indicating a menu.

|-
| 04:44
|Click this arrow. Here we choose '''Feed.'''

|-
| 04:48
| Now click on the next option which says '''Distillate.'''

|-
| 04:51
|Click on the drop down arrow and select '''Distillate.'''

|-
| 04:56
| Similarly for '''bottoms''' choose '''Bottoms'''

|-
| 04:59
| The next option is '''Condenser Duty.'''

|-
| 05:02
|Let me click on it and select '''C-Duty.'''

|-
| 05:07
| Similarly choose '''R-Duty '''for '''Reboiler.'''

|-
| 05:12
|This completes the connectivity of the flowsheet.

|-
| 05:14
| Under '''Properties '''tab, locate '''Parameters '''section.

|-
| 05:19
|This section is used to specify various attributes of a Shortcut Column.

|-
| 05:25
|In this section, the first option is '''Condenser'''.

|-
| 05:30
|By default, it is '''total condenser.'''

|-
| 05:33
|If a '''partial condenser''' is required, you can change it here.

|-
| 05:36
|Here we leave it as it is.

|-
| 05:39
| Let us enter the '''reflux ratio.''' Click on it.

|-
| 05:42
| Here we enter the value '''2''' in the field next to it.

|-
| 05:49
| We will specify the '''Product composition.'''

|-
| 05:52
|Let us first specify light key details in '''bottoms.'''

|-
| 05:57
|To do this, let me click '''light key.'''

|-
| 06:01
|Click the arrow and choose '''Benzene.'''

|-
| 06:04
| In the given field on the next row, enter '''0.05.'''

|-
| 06:10
| Similarly for '''heavy key, '''choose '''Toluene.'''

|-
| 06:15
| Now we specify the heavy key in '''Distillate.'''

|-
| 06:18
|We enter '''0.05.'''

|-
| 06:23
| Next in the list is '''Condenser Pressure.'''

|-
| 06:26
|The default value is '''0 atmosphere.''' We will change it to '''1 atmosphere.'''

|-
| 06:32
| Similarly let us change reboiler pressure to '''1 atmosphere'''

|-
| 06:37
| Now we will run the simulation.

|-
| 06:39
| To do this, go to the '''calculator''' options.

|-
| 06:42
|Click on the '''Play''' button. Now click on the '''Recalculate''' button.

|-
| 06:47
| When the calculations are completed, click on the '''Shortcut column.'''

|-
| 06:53
| Under '''Properties '''tab, locate '''Results '''menu.

|-
| 06:58
|This shows all the required results like

|-
| 07:00
|'''Minimum Reflux Ratio'''

|-
| 07:03
|'''Minimum Number of Stages'''

|-
| 07:05
|'''Actual Number of Stages'''

|-
| 07:07
|'''Optimal Feed Stage, etc.'''

|-
| 07:10
| I have tabulated these results in a slide.

|-
| 07:15
| Let me save this simulation.

|-
| 07:20
|I have saved this as '''shortcut end.'''

|-
| 07:24
| Let me summarise.

|-
| 07:26
| We learnt how to specify a shortcut distillation column.

|-
| 07:29
|To specify key components, purities, and minimum reflux ratio.

|-
| 07:34
|To use custom units.

|-
| 07:36
|To calculate minimum reflux ratio optimal feed location and total number of trays

|-
| 07:43
| Let me give some assignments.

|-
| 07:44
| The assignment in this slide has to do with mass balances.

|-
| 07:48
|I use blue colour to indicate streams and equipment.

|-
| 07:52
| Let us go to the next Assignment.

|-
| 07:54
|Carry out energy balance as mentioned.

|-
| 07:58
| Repeat the simulation with different product purities.

|-
| 08:02
|Determine how the energy requirement changes.

|-
| 08:06
| Repeat this simulation with different thermodynamics.

|-
| 08:08
|Repeat this simulation with different feed conditions.

|-
| 08:12
|Try to reason your results.
