Time
Narration
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 customize 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 theProperties 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 summarize.
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.
08:13 We have come to the end of this tutorial.
