| 00:00 | Welcome to the spoken tutorial on creating a material stream in DWSIM. |
| 00:05 | My name is Kannan Moudgalya. |
| 00:07 | In this tutorial, we are going to learn: |
| 00:10 | * How to select chemical components |
| 00:14 | * How to choose a thermodynamic package |
| 00:17 | * How to choose units and values |
| 00:19 | * And how to specify a material stream. |
| 00:23 | To record this tutorial, I am using DWSIM 3.4 windows version. |
| 00:29 | But this process is identical in Linux, Mac OS X and FOSSEE on ARM. |
| 00:35 | To practice this tutorial, you should have access to DWSIM. |
| 00:39 | Let us start with creating a new steady state simulation. |
| 00:46 | When DWSIM is opened, you see a startup window, such as this. |
| 00:53 | Click on Create new simulation |
| 00:57 | If a simulation wizard appears, cancel it. |
| 01:02 | On the top left, locate a field called Simulation. |
| 01:08 | Hover the mouse over the puzzle like button next to it. |
| 01:14 | You can see that it is known as Configure Simulation. |
| 01:18 | Press this button. |
| 01:23 | A Configure Simulation pop-up opens. |
| 01:26 | In some earlier versions, this pop-up opened automatically. |
| 01:31 | The lettering is very small and unreadable in this recording. |
| 01:35 | To address this, I will zoom in on the relevant portion of this screen only. |
| 01:42 | I have now rearranged the screen for better readability. |
| 01:46 | In the Component Search tab of this window, type "benzene". |
| 01:59 | Benzene appears in two rows. We are interested in the entry that has DWSIM as the database. |
| 02:07 | We will explain in another tutorial the significance of other databases. |
| 02:13 | Double click anywhere on this line. |
| 02:17 | You could have pressed the Add button also which is on the right hand side which we will see shortly. |
| 02:23 | You can see that Benzene is now selected. |
| 02:27 | I shall let you see it by shifting the pop-up window to the left. |
| 02:40 | Repeat this for toluene. |
| 02:52 | Let us select this. Let us add. |
| 02:59 | You can see that the component selection is completed. |
| 03:04 | I shall shift the window back to where it was. |
| 03:12 | We are now ready to choose Thermodynamics. |
| 03:14 | Let us go back to the slides. |
| 03:18 | Let us go to the next slide. |
| 03:21 | This slide has guidelines on how to choose thermodynamics. |
| 03:24 | Covering the theory behind this slide is beyond the scope of this tutorial. |
| 03:30 | As Benzene and Toluene form an ideal solution, we can choose Raoult's law. |
| 03:35 | Let us do this in DWSIM. |
| 03:40 | Locate the Thermodynamics tab on the left hand side. Click on it. |
| 03:47 | A sub-menu appears in the white space above. |
| 03:51 | Click on the Property Packages in the sub-menu. |
| 03:56 | Scroll down in this list and locate an option called Raoult's law. |
| 04:03 | Choose this by double clicking on it. |
| 04:08 | You will see Raoult's law appearing on the right hand side of the pop-up. |
| 04:12 | To see this, let me shift the pop-up to the left. |
| 04:20 | On the lower right hand corner of this pop-up, locate a button called Back to Simulation. Click on it. |
| 04:28 | The configure simulation pop-up gets closed and we are ready to do the simulation. |
| 04:35 | The canvas at the centre of this page is used to create flowsheets. |
| 04:41 | We will now create a material stream. |
| 04:44 | On the right hand side, you see an object palette. |
| 04:49 | It has a large collection of many useful chemical engineering objects. |
| 04:55 | You can scroll it and see what all are available. |
| 05:01 | Right at the top of this is the Material Stream object. Click it and drag it to the flowsheet. |
| 05:12 | At the desired place, remove your finger from the mouse to drop the stream. |
| 05:19 | You may leave it anywhere on this canvas. |
| 05:21 | You can also move the stream to another place later, if required. |
| 05:25 | Immediately after dropping the stream, a pop-up to enter compositions appears. |
| 05:31 | Notice that Mole Fraction is selected by default. |
| 05:36 | You can choose one of the other possibilities. But, I shall leave it as it is. |
| 05:42 | The chemicals that we already selected, appear here automatically. |
| 05:49 | Type 0.5 in the equilibrium composition of Toluene. |
| 05:55 | Press down arrow. |
| 05:57 | Type 0.5 in the Equilibrium Composition of benzene. |
| 06:02 | Click Apply. |
| 06:06 | The total of the mole fractions appears on the right hand side. |
| 06:12 | If the total is not 1, DWSIM 'normalize's the entries, so that the total becomes 1. |
| 06:19 | But this may give some unpredictable values at times. |
| 06:22 | So, you yourself may want to ensure that the total comes to 1. Click the Close button. |
| 06:31 | You can always get back to the previous pop-up by double clicking on the stream. |
| 06:36 | Below the configure simulation button, notice a place to change the System of Units. |
| 06:43 | Let us click this menu and choose CGS System. |
| 06:49 | Let us now complete the specification of this stream. |
| 06:52 | Click on the stream icon in the flowsheet once – do not double click it. |
| 07:00 | On the left hand side of the flowsheet you will see the selected object window |
| 07:07 | This window consists of Properties and Appearance tabs |
| 07:12 | The properties tab shows all the properties of the stream. DWSIM assigns default values to all properties |
| 07:21 | That is first scroll up this page |
| 07:27 | There are many ways to complete the specification of a material stream |
| 07:31 | Press on Specification |
| 07:34 | A down arrow appears on the right hand side – press it |
| 07:40 | The default is to specify pressure and temperature |
| 07:43 | I shall leave it as it is |
| 07:45 | I shall press the down arrow once again to close the menu |
| 07:50 | We see the number 25 already entered against the temperature |
| 07:55 | I will by hovering the mouse over the Temperature, we see the units as degree Celsius |
| 08:02 | Let us click to the right of this number |
| 08:07 | It is an editable field. Let me delete it and enter 30 |
| 08:15 | Let us look at pressure next. I shall leave it at 1 atmosphere |
| 08:23 | Let us specify the flowrate next |
| 08:26 | We can specify mass flowrate or molar flowrate or volumetric flowrate |
| 08:33 | We will specify molar flowrate |
| 08:38 | I shall delete the old value and enter 100 |
| 08:47 | Press enter to save this change |
| 08:50 | Units for this field are moles per second as we can see now |
| 08:56 | It is possible to use a combination of units, such as CGS and SI |
| 09:01 | We will postpone this discussion to another tutorial |
| 09:05 | Now the stream is fully defined |
| 09:08 | DWSIM has given the name MSTR-004 to this stream automatically |
| 09:16 | You may see some other name in your simulation, but do not worry about it |
| 09:21 | As I am not happy with this automatically generated name, let me change it |
| 09:27 | Under the selected object window, click on the appearance tab |
| 09:33 | The Appearance tab is used to modify the visual appearance of the stream |
| 09:37 | Click on the blank space beside Name and type Inlet1 after deleting this. |
| 09:55 | Click on the Name again. |
| 09:58 | You can see the name Inlet1 appearing below this stream in the flowsheet. |
| 10:04 | We will build on this material stream in the upcoming tutorials. |
| 10:08 | Let us go back to the slides. |
| 10:13 | We go to the next slide. |
| 10:15 | Let me summarise what we learnt in this tutorial. |
| 10:19 | We defined a material stream. |
| 10:22 | Chose chemical components. |
| 10:24 | Chose the property estimation package. |
| 10:27 | Completed specifications. |
| 10:29 | Assigned values and units. |
| 10:32 | Specified temperature, pressure and flow rate. |
| 10:36 | Pointed out many different options. |
| 10:40 | I would like to give some assignments now. |
| 10:43 | Choose Benzene and Toluene mole fractions that do not add up to 1. |
| 10:48 | Check how DWSIM normalises when you press apply. |
| 10:53 | Go to the page where you defined mole fractions. |
| 10:57 | Check what the normalise button does when the total is not 1. |
| 11:02 | Go to the page where we defined the molar flow rate. |
| 11:05 | DWSIM automatically displays equivalent flow rates in other units. |
| 11:11 | Check if these values are consistent. |
| 11:16 | Create a stream consisting of Benzene, Toluene and Xylene. |
| 11:20 | Carry out the previous assignments for this stream also |
| 11:26 | This brings us to the end of this tutorial |
| 11:28 | This video summarises the Spoken Tutorial project. |
| 11:33 | If you do not have good bandwidth, you can download and watch it. |
| 11:39 | We conduct workshops using Spoken Tutorials. Give Certificates. Please contact us. |
| 11:47 | The Spoken Tutorial project is funded by NMEICT, MHRD, Govt. of India |
| 11:52 | We thank the DWSIM team for making it as an open source software |
| 11:58 | I want to thank you the listener for joining me in this tutorial, goodbye. |
