<br />
|- <br />
||00:01<br />
|| Welcome to this '''spoken tutorial''' on '''Binary Phase Envelope '''in '''DWSIM'''. <br />
<br />
|- <br />
||00:07<br />
|| In this tutorial, we will learn to generate: '''Txy''' plot at given '''pressure''', <br />
<br />
|- <br />
|| 00:14<br />
|| '''xy''' plot for the obtained '''Txy''' data, <br />
<br />
|- <br />
|| 00:18<br />
|| '''Pxy''' plot at given '''temperature'''. <br />
<br />
|- <br />
|| 00:22<br />
|| To record this tutorial, I am using '''DWSIM 5.2 (Classic UI)''' and '''Windows 10'''. <br />
<br />
|- <br />
|| 00:32<br />
|| The process demonstrated in this tutorial is identical in other '''OS''' also, such as- <br />
<br />
'''Linux''', <br />
<br />
'''Mac OS X '''or <br />
<br />
'''FOSSEE OS '''on '''ARM'''. <br />
<br />
|- <br />
||00:44<br />
|| To practice this tutorial, you should know to : add components to a '''flowsheet''', <br />
<br />
|- <br />
|| 00:51<br />
|| Select '''thermodynamic '''packages,<br />
<br />
|- <br />
|| 00:54<br />
|| add '''material '''streams and specify their properties. <br />
<br />
|- <br />
|| 00:59<br />
|| The pre-requisite tutorials are mentioned on our website.<br />
<br />
|- <br />
|| 01:04<br />
|| You can access these tutorials and all the associated files from this site. <br />
<br />
|- <br />
||01:10<br />
|| In this tutorial, using '''DWSIM''', we will generate: '''Txy''' plot at a constant pressure of '''1.013 bar''', <br />
<br />
|- <br />
|| 01:21<br />
|| '''xy''' plot for the obtained '''Txy''' data, <br />
<br />
|- <br />
|| 01:25<br />
|| '''Pxy''' plot at a constant temperature of '''75 degree centigrade'''. <br />
<br />
|- <br />
|| 01:31<br />
|| Here we give '''compounds, inlet stream conditions''' and '''property package'''. <br />
<br />
|- <br />
|| 01:38<br />
|| I have already opened '''DWSIM '''on my machine. <br />
<br />
|- <br />
|| 01:43<br />
|| Go to '''File '''menu and select '''New Steady-state Simulation.''' <br />
<br />
|- <br />
|| 01:50<br />
|| '''Simulation Configuration Wizard '''window appears. <br />
<br />
|- <br />
|| 01:54<br />
|| At the bottom, click on the '''Next '''button. <br />
<br />
|- <br />
|| 01:58<br />
|| Now, in the '''Compounds Search '''tab, type '''Ethanol.''' <br />
<br />
|- <br />
|| 02:04<br />
|| Select '''Ethanol '''from '''ChemSep '''database. <br />
<br />
|- <br />
|| 02:08<br />
|| Similarly, add '''1-propanol'''. <br />
<br />
|- <br />
|| 02:12<br />
|| At the bottom, click on the '''Next '''button. <br />
<br />
|- <br />
|| 02:16<br />
|| The '''Property Packages '''opens. <br />
<br />
|- <br />
|| 02:19<br />
|| From '''Available Property Packages '''list, double-click on '''Soave-Redlich-Kwong (SRK).''' <br />
<br />
|- <br />
|| 02:26<br />
|| Then click on the '''Next '''button'''.''' <br />
<br />
|- <br />
|| 02:30<br />
|| We are moved to a new window named '''Flash Algorithm'''. <br />
<br />
|- <br />
||02:35<br />
|| From '''Default Flash Algorithm '''select '''Nested Loops(VLE)'''. <br />
<br />
|- <br />
|| 02:41<br />
|| At the bottom, click on the '''Next '''button. <br />
<br />
|- <br />
|| 02:45<br />
|| Next option is '''System of Units.''' <br />
<br />
|- <br />
||02:49<br />
|| Under '''System of Units''', select '''C5'''. <br />
<br />
|- <br />
||02:54<br />
|| At the bottom, click on the '''Finish '''button. <br />
<br />
|- <br />
|| 02:58<br />
|| Let us maximize the '''simulation window''' for better visibility. <br />
<br />
|- <br />
|| 03:03<br />
|| Let’s insert a '''material stream''' for which we have to generate the '''Txy, xy '''and '''Pxy''' plots. <br />
<br />
|- <br />
|| 03:12<br />
|| On the right hand side of the main '''simulation window''', go to '''Flowsheet Objects.''' <br />
<br />
|- <br />
|| 03:19<br />
|| In the '''Filter List '''tab, type '''Material Stream.''' <br />
<br />
|- <br />
|| 03:24<br />
|| From the displayed list, drag and drop a '''Material Stream '''to the '''Flowsheet'''. <br />
<br />
|- <br />
|| 03:30<br />
|| Click on the '''Material Stream “MSTR-000” '''to view its properties. <br />
<br />
|- <br />
|| 03:37<br />
|| Let’s change the name of this '''stream '''to '''Feed.''' <br />
<br />
|- <br />
|| 03:41<br />
|| Now we will specify the '''Feed stream '''properties. <br />
<br />
|- <br />
|| 03:46<br />
|| Go to '''Input Data.''' <br />
<br />
|- <br />
|| 03:48<br />
|| Select '''Flash Spec '''as '''Temperature and Pressure (TP), '''if not already selected. <br />
<br />
|- <br />
|| 03:55<br />
|| By default, '''Temperature and Pressure '''are already selected as '''Flash Spec.''' <br />
<br />
|- <br />
||04:01<br />
|| Change '''Temperature '''to '''30 degree Centigrade '''and press '''Enter.''' <br />
<br />
|- <br />
||04:07<br />
|| Change '''Pressure '''to '''3.5 bar '''and press '''Enter'''. <br />
<br />
|- <br />
|| 04:13<br />
|| Change '''Molar Flow '''to '''120 kmol/h '''and press '''Enter'''. <br />
<br />
|- <br />
|| 04:20<br />
|| Now, let us specify the '''feed stream compositions'''. <br />
<br />
|- <br />
|| 04:25<br />
|| Under '''Composition''', choose the '''Basis '''as '''Mole Fractions, '''if not already selected'''.''' <br />
<br />
|- <br />
|| 04:33<br />
|| By default, '''Mole Fractions '''will be selected as '''Basis.''' <br />
<br />
|- <br />
||04:38<br />
|| For '''Ethanol''', enter the '''Amount '''as '''0.5 '''and press '''Enter'''. <br />
<br />
|- <br />
|| 04:46<br />
|| Similarly, for '''1-propanol''', enter it as '''0.5 '''and press '''Enter'''. <br />
<br />
|- <br />
|| 04:54<br />
|| On the right side, click on this green tick to '''Accept Changes.''' <br />
<br />
|- <br />
||04:59<br />
|| Now ,we will see how '''property package''' calculates '''phase equilibrium''' data of compounds. <br />
<br />
|- <br />
|| 05:06<br />
|| To do this, go to '''Utilities'''. <br />
<br />
|- <br />
|| 05:10<br />
|| Click on '''Add Utility.''' <br />
<br />
|- <br />
|| 05:13<br />
|| In the '''Add Utility '''window, under '''Object Type''', select '''Material Streams.''' <br />
<br />
|- <br />
||05:20<br />
|| Under '''Utility Type''', select '''Binary Phase Envelope.''' <br />
<br />

|| At the bottom, click on the '''Add Utility''' button.<br />
<br />
|- <br />
|| 05:34<br />
|| '''Binary Phase Envelope''' window opens. <br />
<br />
|- <br />
|| 05:37<br />
|| Let us adjust the '''phase envelope window''' for better visibility. <br />
<br />
|- <br />
|| 05:43<br />
|| Enter '''Name''' as '''Txy-plot.''' <br />
<br />
|- <br />
|| 05:49<br />
|| Go to '''Diagram Settings.''' <br />
<br />
|- <br />
|| 05:52<br />
|| Select '''Ethanol''' as '''Compound 1''', if not already selected. <br />
<br />
|- <br />
|| 05:57<br />
|| By default, '''Ethanol''' is selected as '''Compound 1'''. <br />
<br />
|- <br />
|| 06:02<br />
|| Make sure that the other '''compound''' is selected as '''Compound 2'''. <br />
<br />
|- <br />
|| 06:07<br />
|| In this case, it is '''1-propanol''' which is '''Compound 2'''. <br />
<br />
|- <br />
|| 06:12<br />
|| Select '''Envelope type''' as '''Txy''', if not already selected. <br />
<br />
|- <br />
|| 06:19<br />
|| By default, '''Txy''' is selected as '''Envelope type'''. <br />
<br />
|- <br />
|| 06:24<br />
|| Select '''Txy Diagram Options''' as '''VLE''', if not already selected. <br />
<br />
|- <br />
|| 06:31<br />
|| By default, '''VLE''' is selected as '''Txy Diagram Options'''. <br />
<br />
|- <br />
|| 06:36<br />
|| Select '''X-Axis Basis''' as '''Mole Fraction''', if not already selected. <br />
<br />
|- <br />
|| 06:43<br />
|| By default, '''Mole Fraction''' is selected as '''X-Axis Basis''' <br />
<br />
|- <br />
|| 06:48<br />
|| Enter '''Pressure''' as '''1.013 bar.''' <br />
<br />
|- <br />
|| 06:53<br />
|| Here we are going to plot a '''Txy''' diagram. <br />
<br />
|- <br />
|| 06:56<br />
|| So, let's not worry about the '''pressure''' value. <br />
<br />
|- <br />
|| 07:00<br />
|| Make sure that the '''property package''' is selected as '''Soave-Redlich-Kwong.''' <br />
<br />
|- <br />
|| 07:07<br />
|| Now click on '''Calculate''' button at the bottom. <br />
<br />
|- <br />
|| 07:12<br />
|| The diagram generated is a '''Txy''' diagram or '''Constant Pressure Phase Diagram'''. <br />
<br />
|- <br />
|| 07:19<br />
|| '''X-axis''' indicates the '''mole fraction''' of '''Ethanol'''.<br />
<br />
|- <br />
|| 07:23<br />
|| '''Y -axis''' indicates the temperature range for which the '''VLE '''is generated. <br />
<br />
|- <br />
|| 07:29<br />
|| The lower line of the '''envelope''' represents '''Bubble Point''' '''Curve.''' <br />
<br />
|- <br />
|| 07:34<br />
|| Hover the '''mouse''' to the lower line at '''Ethanol mole fraction''' of '''0.5.''' <br />
<br />
|- <br />
|| 07:40<br />
|| We can see the '''bubble point temperature '''to be '''86.2853 degree Centigrade.''' <br />
<br />
|- <br />
|| 07:47<br />
|| For any mixture composition below this line, is '''subcooled liquid'''. <br />
<br />
|- <br />
|| 07:52<br />
|| The upper line of the '''envelope''' represents '''Dew Point Curve.''' <br />
<br />
|- <br />
|| 07:57<br />
|| Hover the mouse to the upper line at '''Ethanol mole fraction''' of '''0.5.''' <br />
<br />
|- <br />
|| 08:03<br />
|| We can see the '''dew point temperature '''to be '''89.5881 degree Centigrade''' <br />
<br />
|- <br />
||08:10<br />
|| For any mixture composition above this line, the mixture is '''superheated vapour'''. <br />
<br />
|- <br />
|| 08:16<br />
|| The area enclosed between these two lines is the '''VLE''' region. <br />
<br />
|- <br />
|| 08:21<br />
|| Here, both vapor and liquid phases exist in equilibrium. <br />
<br />
|- <br />
|| 08:26<br />
|| We can see the '''bubble points''' and '''dew points''' at every composition. <br />
<br />
|- <br />
