||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'''.

|| '''xy''' plot for the obtained '''Txy''' data,
 
 
|-
 
|| 01:25

|-
 
|| 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.'''

|-
 
|| 01:58
 
|| Now, in the '''Compounds Search '''tab, type '''Ethanol.'''
 
 
|-
 
|| 02:04
 
|| Select '''Ethanol '''from '''ChemSep '''database.
 
 
|-
 
|| 02:08

|-
 
|| 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.

|-
 
|| 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
