00:01 Welcome to this tutorial on Creating a Material Stream in DWSIM.
00:07 In this tutorial, we will learn to:
00:10 Select Chemical compounds
00:13 Define a Thermodynamic package
00:16 Choose Units and Values and
00:19 Specify a Material stream
00:22 This tutorial is recorded using

DWSIM version 5. 8 (Classic UI) Update 3 and Windows 10 OS

00:32 But, this process is identical in Linux, Mac OS X or FOSSEE OS on ARM.
00:40 You should have DWSIM installed on your machine.
00:44 Let us start by creating a new steady state simulation.
00:48 To open DWSIM, go to the Desktop.
00:52 Right-click on DWSIM and click Run as Administrator.
00:59 DWSIM window opens.
01:02 Close the Tasks window.
01:05 Go to File menu and select New Steady-state Simulation.
01:11 Simulation Configuration Wizard window opens.
01:15 Click on the Next button at the bottom of the window.
01:20 First, we will add the compounds.
01:23 In the Compounds Search tab, type Benzene.
01:28 Select Benzene from ChemSep database.
01:32 Under Added column, check the checkbox for Benzene.
01:37 We can also double-click anywhere on this line.
01:41 Similarly, add Toluene from ChemSep database.
01:46 Then click on Next button at the bottom to continue.
01:52 The Property Packages window opens.
01:56 As Benzene and Toluene form an ideal solution, we can choose Raoult's law.
02:02 From Available Property Packages list, double-click on Raoult’s Law.
02:09 Now click on the Next button at the bottom.
02:13 Next option is System of Units.
02:17 Under System of Units, we will select CGS.
02:22 Then click on the Finish button at the bottom.
02:27 Let us maximize the Simulation window.
02:30 The canvas at the centre is used to create the flowsheets.
02:35 We will now create a material stream.
02:38 At the bottom of the main simulation window, we can see an Object Palette.
02:43 It has a large collection of many useful chemical engineering objects.
02:48 Go to Streams tab.
02:50 From the displayed list, drag and drop a material stream to the flowsheet.
02:56 Let us arrange the stream.
02:59 Click on the material stream named as MSTR-000.
03:04 DWSIM has given the name MSTR-000 to this stream automatically.

Let me change it.

03:13 On the left hand side of the flowsheet we can see the Property Editor Window.
03:18 Under General Info, type the Object as Inlet1.

Press Enter.

03:25 We can see the name Inlet1 appearing below this stream in the flowsheet.
03:31 Now let us specify the feed stream compositions.
03:35 Under Input Data, click on Compound Amounts tab.
03:40 Choose the Basis as Mole Fractions, if not already selected.
03:45 By default, Mole Fractions is selected as Basis.
03:50 Now for Benzene, enter the Amount as 0.4 and press Enter.
03:58 For Toluene, enter 0.6 and press Enter.
04:04 On the right, click on Accept Changes button.
04:09 The total of the mole fractions appears on the right hand side.
04:14 If the total is not 1, DWSIM normalises the entries, so that the total becomes 1.
04:21 Now we will specify the Feed stream properties.
04:25 The Input Data tab shows all the properties of the stream.
04:30 DWSIM assigns default values to all properties.
04:34 Go to Input Data.
04:37 Under Stream Conditions tab, select Flash Spec as Temperature and Pressure (TP) if not already selected.
04:46 By default, Temperature and Pressure should already be selected as Flash Spec.
04:52 Change Temperature to 30 degree Centigrade and press Enter.
04:58 Change Pressure to 1 atmosphere and press Enter.
05:04 Change Molar Flow to 100 mol per second and press Enter.
05:10 Let us now save this file using the Save As option.
05:15 I will save it as stream.
05:19 Close the Property Editor Window.
05:22 We can always get back to the previous pop-up by double-clicking on the stream.
05:28 We will build on this material stream in the upcoming tutorials.
05:33 Let me go back to the slides.
05:36 Let's summarize.
05:38 In this tutorial, we have learnt to
05:40 Select Chemical compounds
05:43 Define a Thermodynamic package
05:46 Choose Units and Values and
05:49 Specify a material stream
05:52 Here are some assignments for you.
05:55 Choose Benzene and Toluene mole fractions that do not add up to 1.
06:00 Check how DWSIM normalises when you press Accept Changes button.
06:05 Go to the page where you defined mole fractions.
06:10 Check what the Normalize button does when the Total is not 1.
06:15 Go to the page where we defined the molar flow rate.
06:19 DWSIM automatically displays equivalent flow rates in other units.
06:25 Check if these values are consistent.
06:29 Create a stream consisting of Benzene, Toluene and Xylene.
06:35 Carry out the previous assignments for this stream also.
06:40 This brings us to the end of this tutorial.
06:44 Watch the video available at the following link.

It summarizes the Spoken Tutorial project.

06:52 The Spoken Tutorial Project Team conducts workshops and gives certificates.

07:36 Spoken Tutorial and FOSSEE projects are funded by NMEICT, MHRD, Government of India.
07:45 We thank the DWSIM team for making it as an open source software.
07:51 This tutorial was originally recorded by Prof Kannan Moudgalya in May 2015.

This is Kaushik Datta from IIT Bombay. Thanks for joining.
