Time
Narration
00:01 Welcome to the spoken tutorial on Introduction to Flowsheeting in DWSIM.
00:07 In this tutorial, We will simulate a mixer.
00:10 Follow it up with a flash separator.
00:12 Learn how to give a two phase feed.
00:16 To record this tutorial, I am using DWSIM 3.4.
00:20 To practice this tutorial, you should have an exposure to DWSIM.
00:24 The prerequisite tutorials are mentioned on our website: spoken hyphen tutorial dot org.
00:31 Let me open DWSIM.
00:33 I have already opened a file flow-begin with two material streams.
00:40 I have selected Raoult’s law and the CGS system.
00:43 I went through file menu and the open option to get this. Let me close this.
00:53 This file is available at our "spoken tutorial" website.
00:56 You may download this and use it or you can manually enter the required information.
01:02 You can see two streams Inlet1 and Inlet2 in the flowsheet canvas.
01:08 The next slide summarizes the contents of this file.
01:13 When we mix these streams, we get equimolar composition.
01:17 We have chosen these values to easily verify the calculations of DWSIM.
01:23 Let us go back to DWSIM.
01:25 We will now modify the streams so as to have vapor in them.
01:31 Select Inlet 1.
01:34 At the top of the Properties tab, locate Specification. Click on it.
01:40 Press the down-arrow and choose Pressure and Vapor Fraction.
01:46 Scroll down and locate Molar Fraction Vapor Phase.
01:53 Enter 1 here, that is, the entire stream is a vapor.
02:00 In a similar way, make Inlet2 to have 50% Molar Fraction.
02:13 Now, let us insert a mixer to the flowsheet.
02:17 Locate the Mixer from the object palette. It is the third entry.
02:22 Click and drag it to the flowsheet.
02:24 Let us change the name of the mixer now.
02:29 Click on the Appearance tab. Delete the default name and enter Mixer.
02:36 Now let us insert an output stream for the mixer.
02:40 Click on Material Stream and drag it to the flowsheet.
02:45 We will close the automatic pop-up and not enter anything. Because, all output streams should be left unspecified.
02:54 We will change the name of this stream to mixer-out.
03:03 Let me connect the streams to the mixer.
03:05 Let me click the mixer once.
03:08 Properties show up in the Selected Object window.
03:12 You can see that the mixer has up to 6 inlet streams.
03:19 Let us click on Inlet Stream 1.
03:23 A down-arrow appears, indicating a menu.
03:27 Click this arrow and choose Inlet1.
03:32 Similarly, connect Inlet2 at Inlet Stream 2.
03:37 Locate the outlet port, mentioned as Connected to Outlet here.
03:43 Click on it and choose mixer-out.
03:49 We can move the streams to make them better aligned.
03:54 The mixer is red, as it is not calculated yet.
03:58 To the right of the configure simulation button is calculator.
04:02 It has several options.
04:03 The first one is the play button, to activate the solver. Press it.
04:09 Two buttons to the right of this are for Recalculate action. Click this button.
04:17 The mixer has become blue now, it means that the calculations are completed.
04:22 Now click on mixer-out stream.
04:27 We can see its calculated values in the Properties tab.
04:31 We can verify that its composition is as expected.
04:37 Double click Mixture.
04:40 It has equimolar composition.
04:43 Now let us insert a flash separator.
04:47 Let us scroll down the Object Palette.
04:51 Let us locate the Separator Vessel.
04:56 It can be used to simulate VLE, LLE and VLLE systems.
05:01 Click and drag it to the flowsheet.
05:06 We need to connect two output streams to the separator.
05:10 Let us drag the material stream.
05:13 We will leave it unspecified, as its properties are to be calculated.
05:20 We will name it as Vapour.
05:27 Similarly, create another stream and name it as Liquid.
05:32 Let us now connect the streams to the Separator.
05:36 In the first input port, we will connect mixer-out.
05:44 We can connect a total of five more input streams.
05:47 The separator mixes all the streams and separates. As a matter of fact, a separate mixer is not really required.
05:54 It also has a port to connect an energy stream
05:59 as we can see now.
06:02 These ideas will be taken up in the assignment section.
06:07 Let us connect the Vapour stream to the Vapour outlet port.
06:13 Similarly, connect the Liquid stream.
06:21 Once again, we can move the items for better alignment.
06:26 Notice that DWSIM completed the calculations automatically.
06:31 You are free to press the Recalculate button also.
06:35 In fact, you should do this whenever you are in doubt.
06:39 We now check whether the vapor and liquid are split properly in the separator.
06:45 Let us look at the vapor phase mole fractions of the stream Vapour.
06:52 The mole fraction of Benzene is 0.54.
06:56 Let us check whether this is in agreement with what mixer-out has.
07:04 You can see that DWSIM automatically displays vapor value. The benzene mole fraction is 0.54.
07:13 This is an indirect evidence that the Separator is working as expected.
07:18 We can do a check on the working of the Mixer also.
07:22 You can see the Mixture composition is equimolar, as expected.
07:29 We will postpone a few other checks to the Assignment Section.
07:34 Let us save this file using the save as option.
07:39 I will save it as flow-end.
07:46 I suggest that you keep saving your work frequently.
07:49 Let me summarize.
07:52 * We defined a simple flowsheet.
07:54 * Explained how to create mixed feed.
07:58 * Introduced mixer and separator.
08:00 * Showed how to connect them.
08:02 * Explained how to simulate.
08:04 Let me give some assignments.
08:07 The assignment in this slide has to do with mass balances.
08:10 I use blue colour to indicate streams and equipment.
08:15 Let us go to the next assignment.
08:16 You have to verify mole fractions as mentioned in this slide.
08:20 The third assignment has to do with the Separator.
08:25 Recall that we mentioned that it could be used to mix streams.
08:30 Remove the mixer and mixer-out and try it out.
08:35 In the next assignment, you will do the separation at a higher temperature.
08:41 Click on Separator. Let's scroll up.
08:46 Let us change Override separation temperature to true.
08:52 In the resulting field, change the value to 100.
08:59 Bring Energy stream from Object Palette to the Flowsheet. This is a new stream.
09:07 Connect this stream to the Energy Stream of the Separator that I showed earlier.
09:13 Simulate and analyze your results.
09:16 This is summarized in the slide here.
09:22 This video summarizes the Spoken Tutorial project.
09:26 If you do not have good bandwidth, you may download and watch it.
