&lt;br /&gt;
|- &lt;br /&gt;
||00:01&lt;br /&gt;
|| Welcome to this '''spoken tutorial''' on '''Binary Phase Envelope '''in '''DWSIM'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
||00:07&lt;br /&gt;
|| In this tutorial, we will learn to generate:  '''Txy''' plot at given '''pressure''', &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 00:14&lt;br /&gt;
||  '''xy''' plot for the obtained '''Txy''' data, &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 00:18&lt;br /&gt;
||  '''Pxy''' plot at given '''temperature'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 00:22&lt;br /&gt;
|| To record this tutorial, I am using  '''DWSIM 5.2 (Classic UI)''' and   '''Windows 10'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 00:32&lt;br /&gt;
|| The process demonstrated in this tutorial is identical in other '''OS''' also, such as- &lt;br /&gt;
&lt;br /&gt;
'''Linux''', &lt;br /&gt;
&lt;br /&gt;
'''Mac OS X '''or &lt;br /&gt;
&lt;br /&gt;
'''FOSSEE OS '''on '''ARM'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
||00:44&lt;br /&gt;
|| To practice this tutorial, you should know to : add components to a '''flowsheet''', &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 00:51&lt;br /&gt;
||  Select '''thermodynamic '''packages,&lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 00:54&lt;br /&gt;
||  add '''material '''streams and specify their properties. &lt;br /&gt;
 &lt;br /&gt;
|- &lt;br /&gt;
|| 00:59&lt;br /&gt;
|| The pre-requisite tutorials are mentioned on our website.&lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 01:04&lt;br /&gt;
|| You can access these tutorials and all the associated files from this site. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
||01:10&lt;br /&gt;
|| In this tutorial, using '''DWSIM''', we will generate:  '''Txy''' plot at a constant pressure of '''1.013 bar''', &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 01:21&lt;br /&gt;
|| '''xy''' plot for the obtained '''Txy''' data, &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 01:25&lt;br /&gt;
||  '''Pxy''' plot at a constant temperature of '''75 degree centigrade'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 01:31&lt;br /&gt;
|| Here we give '''compounds, inlet stream conditions''' and '''property package'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 01:38&lt;br /&gt;
|| I have already opened '''DWSIM '''on my machine. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 01:43&lt;br /&gt;
|| Go to '''File '''menu and select '''New Steady-state Simulation.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 01:50&lt;br /&gt;
|| '''Simulation Configuration Wizard '''window appears. &lt;br /&gt;
 &lt;br /&gt;
|- &lt;br /&gt;
|| 01:54&lt;br /&gt;
|| At the bottom, click on the '''Next '''button. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 01:58&lt;br /&gt;
|| Now, in the '''Compounds Search '''tab, type '''Ethanol.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 02:04&lt;br /&gt;
|| Select '''Ethanol '''from '''ChemSep '''database. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 02:08&lt;br /&gt;
|| Similarly, add '''1-propanol'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 02:12&lt;br /&gt;
|| At the bottom, click on the '''Next '''button. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 02:16&lt;br /&gt;
|| The '''Property Packages '''opens. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 02:19&lt;br /&gt;
|| From '''Available Property Packages '''list, double-click on '''Soave-Redlich-Kwong (SRK).''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 02:26&lt;br /&gt;
|| Then click on the '''Next '''button'''.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 02:30&lt;br /&gt;
|| We are moved to a new window named '''Flash Algorithm'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
||02:35&lt;br /&gt;
|| From '''Default Flash Algorithm '''select '''Nested Loops(VLE)'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 02:41&lt;br /&gt;
|| At the bottom, click on the '''Next '''button. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 02:45&lt;br /&gt;
|| Next option is '''System of Units.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
||02:49&lt;br /&gt;
|| Under '''System of Units''', select '''C5'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
||02:54&lt;br /&gt;
|| At the bottom, click on the '''Finish '''button. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 02:58&lt;br /&gt;
|| Let us maximize the '''simulation window''' for better visibility. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 03:03&lt;br /&gt;
|| Let’s insert a '''material stream''' for which we have to generate the '''Txy, xy '''and '''Pxy''' plots. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 03:12&lt;br /&gt;
|| On the right hand side of the main '''simulation window''', go to '''Flowsheet Objects.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 03:19&lt;br /&gt;
|| In the '''Filter List '''tab, type '''Material Stream.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 03:24&lt;br /&gt;
|| From the displayed list, drag and drop a '''Material Stream '''to the '''Flowsheet'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 03:30&lt;br /&gt;
|| Click on the '''Material Stream “MSTR-000” '''to view its properties. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 03:37&lt;br /&gt;
|| Let’s change the name of this '''stream '''to '''Feed.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 03:41&lt;br /&gt;
|| Now we will specify the '''Feed stream '''properties. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 03:46&lt;br /&gt;
|| Go to '''Input Data.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 03:48&lt;br /&gt;
|| Select '''Flash Spec '''as '''Temperature and Pressure (TP), '''if not already selected. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 03:55&lt;br /&gt;
|| By default, '''Temperature and Pressure '''are already selected as '''Flash Spec.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
||04:01&lt;br /&gt;
|| Change '''Temperature '''to '''30 degree Centigrade '''and press '''Enter.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
||04:07&lt;br /&gt;
|| Change '''Pressure '''to '''3.5 bar '''and press '''Enter'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 04:13&lt;br /&gt;
|| Change '''Molar Flow '''to '''120 kmol/h '''and press '''Enter'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 04:20&lt;br /&gt;
|| Now, let us specify the '''feed stream compositions'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 04:25&lt;br /&gt;
|| Under '''Composition''', choose the '''Basis '''as '''Mole Fractions, '''if not already selected'''.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 04:33&lt;br /&gt;
|| By default, '''Mole Fractions '''will be selected as '''Basis.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
||04:38&lt;br /&gt;
|| For '''Ethanol''', enter the '''Amount '''as '''0.5 '''and press '''Enter'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 04:46&lt;br /&gt;
|| Similarly, for '''1-propanol''', enter it as '''0.5 '''and press '''Enter'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 04:54&lt;br /&gt;
|| On the right side, click on this green tick to '''Accept Changes.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
||04:59&lt;br /&gt;
|| Now ,we will see how '''property package''' calculates '''phase equilibrium''' data of compounds. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 05:06&lt;br /&gt;
|| To do this, go to '''Utilities'''. &lt;br /&gt;
 &lt;br /&gt;
|- &lt;br /&gt;
|| 05:10&lt;br /&gt;
|| Click on '''Add Utility.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 05:13&lt;br /&gt;
|| In the '''Add Utility '''window, under '''Object Type''', select '''Material Streams.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
||05:20&lt;br /&gt;
|| Under '''Utility Type''', select '''Binary Phase Envelope.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 05:25&lt;br /&gt;
|| Under '''Flowsheet Object''', select '''Feed.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 05:29&lt;br /&gt;
|| At the bottom, click on the '''Add Utility''' button.&lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 05:34&lt;br /&gt;
|| '''Binary Phase Envelope''' window opens. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 05:37&lt;br /&gt;
|| Let us adjust the '''phase envelope window''' for better visibility. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 05:43&lt;br /&gt;
|| Enter '''Name''' as '''Txy-plot.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 05:49&lt;br /&gt;
|| Go to '''Diagram Settings.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 05:52&lt;br /&gt;
|| Select '''Ethanol''' as '''Compound 1''', if not already selected. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 05:57&lt;br /&gt;
|| By default, '''Ethanol''' is selected as '''Compound 1'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 06:02&lt;br /&gt;
|| Make sure that the other '''compound''' is selected as '''Compound 2'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 06:07&lt;br /&gt;
|| In this case, it is '''1-propanol''' which is '''Compound 2'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
||  06:12&lt;br /&gt;
|| Select '''Envelope type''' as '''Txy''', if not already selected. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 06:19&lt;br /&gt;
|| By default, '''Txy''' is selected as '''Envelope type'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 06:24&lt;br /&gt;
|| Select '''Txy Diagram Options''' as '''VLE''', if not already selected. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 06:31&lt;br /&gt;
|| By default, '''VLE''' is selected as '''Txy Diagram Options'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 06:36&lt;br /&gt;
|| Select '''X-Axis Basis''' as '''Mole Fraction''', if not already selected. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 06:43&lt;br /&gt;
|| By default, '''Mole Fraction''' is selected as '''X-Axis Basis''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 06:48&lt;br /&gt;
|| Enter '''Pressure''' as '''1.013 bar.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 06:53&lt;br /&gt;
|| Here we are going to plot a '''Txy''' diagram. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 06:56&lt;br /&gt;
|| So, let's not worry about the '''pressure''' value. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 07:00&lt;br /&gt;
|| Make sure that the '''property package''' is selected as '''Soave-Redlich-Kwong.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 07:07&lt;br /&gt;
|| Now click on '''Calculate''' button at the bottom. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 07:12&lt;br /&gt;
|| The diagram generated is a '''Txy''' diagram or '''Constant Pressure Phase Diagram'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 07:19&lt;br /&gt;
|| '''X-axis''' indicates the '''mole fraction''' of '''Ethanol'''.&lt;br /&gt;
 &lt;br /&gt;
|- &lt;br /&gt;
|| 07:23&lt;br /&gt;
|| '''Y -axis''' indicates the temperature range for which the '''VLE '''is generated. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 07:29&lt;br /&gt;
|| The lower line of the '''envelope''' represents '''Bubble Point''' '''Curve.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 07:34&lt;br /&gt;
|| Hover the '''mouse''' to the lower line at '''Ethanol mole fraction'''  of '''0.5.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 07:40&lt;br /&gt;
|| We can see the '''bubble point temperature '''to be '''86.2853 degree  Centigrade.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 07:47&lt;br /&gt;
|| For any mixture composition below this line, is '''subcooled liquid'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 07:52&lt;br /&gt;
|| The upper line of the '''envelope''' represents '''Dew Point Curve.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 07:57&lt;br /&gt;
|| Hover the mouse to the upper line at '''Ethanol mole fraction''' of '''0.5.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 08:03&lt;br /&gt;
|| We can see the '''dew point temperature '''to be '''89.5881 degree Centigrade''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
||08:10&lt;br /&gt;
|| For any mixture composition above this line, the mixture is '''superheated vapour'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 08:16&lt;br /&gt;
|| The area enclosed between these two lines is the '''VLE''' region. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 08:21&lt;br /&gt;
|| Here, both vapor and liquid phases exist in equilibrium. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 08:26&lt;br /&gt;
|| We can see the '''bubble points''' and '''dew points''' at every composition. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 08:32&lt;br /&gt;
|| For this, go to '''Results''' section and click on '''Table'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 08:37&lt;br /&gt;
|| Here we can see the corresponding '''mole fractions''' and '''temperatures '''values. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 08:43&lt;br /&gt;
|| Let us now generate the '''xy''' plot for data obtained in the above '''Txy''' diagram. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 08:49&lt;br /&gt;
|| Close this '''window'''. &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 08:53&lt;br /&gt;
|| Go to '''Utilities''' and click on '''Add Utility.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
||08:58&lt;br /&gt;
|| In the '''Add Utility '''window, under '''Object Type''', select '''Material Streams.''' &lt;br /&gt;
&lt;br /&gt;
|- &lt;br /&gt;
|| 09:06&lt;br /&gt;
