Time Narration
00:01 Welcome to this spoken tutorial on Binary Phase Envelope in DWSIM.
00:07 In this tutorial, we will learn to generate: Txy plot at given pressure,
00:14 xy plot for the obtained Txy data,
00:18 Pxy plot at given temperature.
00:22 To record this tutorial, I am using DWSIM 5.2 (Classic UI) and Windows 10.
00:32 The process demonstrated in this tutorial is identical in other OS also, such as-

Linux,

Mac OS X or

FOSSEE OS on ARM.

00:44 To practice this tutorial, you should know to : add components to a flowsheet,
00:51 Select thermodynamic packages,
00:54 add material streams and specify their properties.
00:59 The pre-requisite tutorials are mentioned on our website.
01:04 You can access these tutorials and all the associated files from this site.
01:10 In this tutorial, using DWSIM, we will generate: Txy plot at a constant pressure of 1.013 bar,
01:21 xy plot for the obtained Txy data,
01:25 Pxy plot at a constant temperature of 75 degree centigrade.
01:31 Here we give compounds, inlet stream conditions and property package.
01:38 I have already opened DWSIM on my machine.
01:43 Go to File menu and select New Steady-state Simulation.
01:50 Simulation Configuration Wizard window appears.
01:54 At the bottom, click on the Next button.
01:58 Now, in the Compounds Search tab, type Ethanol.
02:04 Select Ethanol from ChemSep database.
02:08 Similarly, add 1-propanol.
02:12 At the bottom, click on the Next button.
02:16 The Property Packages opens.
02:19 From Available Property Packages list, double-click on Soave-Redlich-Kwong (SRK).
02:26 Then click on the Next button.
02:30 We are moved to a new window named Flash Algorithm.
02:35 From Default Flash Algorithm select Nested Loops(VLE).
02:41 At the bottom, click on the Next button.
02:45 Next option is System of Units.
02:49 Under System of Units, select C5.
02:54 At the bottom, click on the Finish button.
02:58 Let us maximize the simulation window for better visibility.
03:03 Let’s insert a material stream for which we have to generate the Txy, xy and Pxy plots.
03:12 On the right hand side of the main simulation window, go to Flowsheet Objects.
03:19 In the Filter List tab, type Material Stream.
03:24 From the displayed list, drag and drop a Material Stream to the Flowsheet.
03:30 Click on the Material Stream “MSTR-000” to view its properties.
03:37 Let’s change the name of this stream to Feed.
03:41 Now we will specify the Feed stream properties.
03:46 Go to Input Data.
03:48 Select Flash Spec as Temperature and Pressure (TP), if not already selected.
03:55 By default, Temperature and Pressure are already selected as Flash Spec.
04:01 Change Temperature to 30 degree Centigrade and press Enter.
04:07 Change Pressure to 3.5 bar and press Enter.
04:13 Change Molar Flow to 120 kmol/h and press Enter.
04:20 Now, let us specify the feed stream compositions.
04:25 Under Composition, choose the Basis as Mole Fractions, if not already selected.
04:33 By default, Mole Fractions will be selected as Basis.
04:38 For Ethanol, enter the Amount as 0.5 and press Enter.
04:46 Similarly, for 1-propanol, enter it as 0.5 and press Enter.
04:54 On the right side, click on this green tick to Accept Changes.
04:59 Now ,we will see how property package calculates phase equilibrium data of compounds.
05:06 To do this, go to Utilities.
05:10 Click on Add Utility.
05:13 In the Add Utility window, under Object Type, select Material Streams.
05:20 Under Utility Type, select Binary Phase Envelope.
05:25 Under Flowsheet Object, select Feed.

05:37 Let us adjust the phase envelope window for better visibility.
05:43 Enter Name as Txy-plot.
05:49 Go to Diagram Settings.
05:52 Select Ethanol as Compound 1, if not already selected.
05:57 By default, Ethanol is selected as Compound 1.
06:02 Make sure that the other compound is selected as Compound 2.
06:07 In this case, it is 1-propanol which is Compound 2.
06:12 Select Envelope type as Txy, if not already selected.
06:19 By default, Txy is selected as Envelope type.
06:24 Select Txy Diagram Options as VLE, if not already selected.
06:31 By default, VLE is selected as Txy Diagram Options.
06:36 Select X-Axis Basis as Mole Fraction, if not already selected.
06:43 By default, Mole Fraction is selected as X-Axis Basis
06:48 Enter Pressure as 1.013 bar.
06:53 Here we are going to plot a Txy diagram.
06:56 So, let's not worry about the pressure value.
07:00 Make sure that the property package is selected as Soave-Redlich-Kwong.
07:07 Now click on Calculate button at the bottom.
07:12 The diagram generated is a Txy diagram or Constant Pressure Phase Diagram.
07:19 X-axis indicates the mole fraction of Ethanol.
07:23 Y -axis indicates the temperature range for which the VLE is generated.
07:29 The lower line of the envelope represents Bubble Point Curve.
07:34 Hover the mouse to the lower line at Ethanol mole fraction of 0.5.
07:40 We can see the bubble point temperature to be 86.2853 degree Centigrade.
07:47 For any mixture composition below this line, is subcooled liquid.
07:52 The upper line of the envelope represents Dew Point Curve.
07:57 Hover the mouse to the upper line at Ethanol mole fraction of 0.5.
08:03 We can see the dew point temperature to be 89.5881 degree Centigrade
08:10 For any mixture composition above this line, the mixture is superheated vapour.
08:16 The area enclosed between these two lines is the VLE region.
08:21 Here, both vapor and liquid phases exist in equilibrium.
08:26 We can see the bubble points and dew points at every composition.
08:32 For this, go to Results section and click on Table.
08:37 Here we can see the corresponding mole fractions and temperatures values.
08:43 Let us now generate the xy plot for data obtained in the above Txy diagram.
08:49 Close this window.
08:53 Go to Utilities and click on Add Utility.
08:58 In the Add Utility window, under Object Type, select Material Streams.
09:06 Under Utility Type, select Binary Phase Envelope.
09:11 Under Flowsheet Object, select Feed.
09:15 At the bottom, click on the Add Utility button.
09:19 Once again, Binary Phase Envelope window opens.
09:23 Let us adjust the window for better visibility.
09:27 Enter Name as xy-plot.
09:32 Go to Diagram Settings.
09:35 Let the Compound settings be the default settings.
09:39 Select Envelope type as (T)xy.
09:44 Select X-Axis Basis as Mole Fraction, if not already selected.
09:51 By default, Mole Fraction is selected as X-Axis Basis.
09:56 Enter Pressure as 1.013 bar.
10:01 Now click on the Calculate button at the bottom.
10:05 The diagram is generated is called xy diagram.
10:09 X-axis indicates the mole fraction of Ethanol in liquid phase.
10:15 Y -axis indicates the mole fraction of Ethanol in vapour phase.
10:20 The upper curve is called Equilibrium Curve.
10:24 Hover the mouse to the upper line at Ethanol mole fraction of 0.6.
10:30 We can see the vapour phase mole fraction of Ethanol to be 0.7539.
10:37 Let us generate the Pxy plot now.
10:41 Close this window.
10:45 Go to Utilities and click on Add Utility.
10:50 In the Add Utility window, under Object Type, select Material Streams.
10:57 Under Utility Type, select Binary Phase Envelope.
11:02 Under Flowsheet Object, select Feed.
11:06 At the bottom, click on the Add Utility button.
11:10 Once again, Binary Phase Envelope window opens.
11:14 Let us adjust the window for better visibility.
11:18 Enter Name as Pxy-plot.
11:23 Go to Diagram Settings.
11:25 Let the Compound settings be the default settings.
11:29 Select Envelope type as Pxy.
11:33 Select X-Axis Basis as Mole Fraction, if not already selected.
11:39 By default, Mole Fraction is selected as X-Axis Basis.
11:44 Enter Temperature as 75 degree Centigrade.
11:49 Here, we are going to plot a Pxy diagram.
11:53 So, let us not worry about the temperature value.
11:57 Make sure that the property package is selected as Soave-Redlich-Kwong.
12:03 Now, click on Calculate button at the bottom.
12:07 The diagram generated is a Pxy diagram or Constant Temperature Phase Diagram.
12:13 X-axis indicates the mole fraction of Ethanol.
12:17 Y -axis indicates the pressure range for which the VLE is generated.
12:23 The lower line of the envelope represents Dew Points.
12:28 Hover the mouse to the lower line at Ethanol mole fraction of 0.4.
12:34 We can see the dew point pressure to be 0.523 bar.
12:39 For any mixture composition below this line, is completely vapour.
12:45 The upper line of the envelope represents Bubble Points.
12:49 Hover the mouse to the upper line at Ethanol mole fraction of 0.8.
12:55 We can see the bubble point pressure to be 0.782 bar.
13:01 For any mixture composition above this line, is completely liquid.
13:06 The area enclosed between these two lines is the VLE region.
13:11 Here, both vapor and liquid phases exist in equilibrium.
13:16 Now, go to Results section. Click on Table.
13:21 Here we can see the corresponding mole fractions and pressure values.
13:27 Let's summarize.
13:29 In this tutorial, we have learnt to generate: Txy plot at given pressure,
