| 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. |
