The process simulation is the action that executes all necessary calculations needed to solve the outcome of the system, hence predicting its behavior. The following series of steps will create a process model for the tubular reactor PFR example problem taken from the 4th Edition of Elements of Chemical Reaction Engineering by H. Scott Fogler. Determine the plug-flow reactor volume necessary to produce million pounds of ethylene a year from cracking a feed stream of pure ethane.
The reaction is irreversible and elementary. The easiest way to create the flowsheet is to start with the Unit Operation and add the streams to it. You have finished adding the inlet stream. Note this example only has one arrow representing the ethane feed.
More than one inlet stream can be drawn. You can specify multiple components in one stream. At this point your screen should look something like this:. You are now ready to add the outlet stream containing both ethylene and hydrogen to your flowsheet. Repeat the steps described above for the inlet stream, however instead of highlighting the red arrow at the top of the reactor, highlight the red arrow ar the bottom.
Of course, for other examples, there could be more than one outlet stream. If you did not connect the stream to the unit when you created the stream, you can still attatch it to the unit. Now that the process flowsheet is complete, it is time to enter the process conditions. In the bottom right of the screen the warngin message has changed from « Flowsheet Not Complete » to « Required Input Incomplete ». This means that entering conditions, operating conditions or kinetic information is missing.
When each input is complete, a will appear next to the completed section in the explorer window on the left. The next input window is Components Specifications. Here is where all of the chemical species in your process model are specified.
The next window to appear is Properties Specifications. Here is where you specify the solving engine used to simulate your process model. Once the required properties information has been input and you click the next button, a window will pop up asking weather to continue to the next step or to modify the properties. Check the circle next to Go to Next required input step. The next window to appear is Streams.
Here is where you specify the components, temperature and pressure of input streams. The next input window is titled B1. This window is where you will specify the operating conditions of the PFR. This is the window you will come back to upon running the simulation to change any operating conditions as well.
The next input is under the Kinetic tab. Here you will describe the rate law of the reaction in the PFR. You are finished entering all the required data for the process model! You will see Required Input Complete in the bottom right corner of the window. Click the Next button again and a window will appear asking if you wish to run the simulation. Click OK. Congratulations on completing the flowsheet and entering the process model conditions.
Now you are ready to put your model to the test. Example , the cracking reaction, can now be simulated. When the simulation is complete, the Control Panel will read: Simulation calculations completed. Note that, down the left side of the screen, are the different parameters: temperature, pressure, mole flow, etc. Along the top row are the stream id names, in this case 1 and 2 inlet and product. This forms a grid of information that can be interpreted easily. As you recall, when entering the process model conditions, you guessed a volume by entering an arbitrary length and diameter of the PFR.
In order to complete the problem, you must see what conversion your process model obtained. Therefore, you need to go back and adjust them. It is easiest to vary the length of the PFR while holding the diameter constant. In Example , you will find that a length of This section is devoted to example reaction problems. Both problems come from Example , the first is an adiabatic reactor and the second is a PFR with constant cooling temperature.
Please note, it is assumed that the user knows how to create a flowsheet and enter process conditions , since these examples explain only the values to enter for each input window. In this design, it is desired to feed kg of acetone per hour to a tubular reactor. If the reactor is adiabatic, the feed pure acetone, the inlet temperature K, and the pressure 1 62 kPa 1. The flowsheet consists of one inlet stream, a PFR, and one product stream. It should look like this:. If you do not know how, see Example When the flowsheet is complete, Required Input Incomplete should appear in the lower right corner of the screen.
Click the Next button. This section will explain what values to type in for each input window. If you do not know how to enter values, change units, or navigate through the input windows, see Example Click Next again until you are prompted to run the simulation. When the simulation is complete, click next and choose to Display Run-Status results form.
If you do not know how to interpret the results window, see Example Therefore, you need to go back to the PFR and input a smaller length. You must access the Rplug. Main window to do this. If you do not know how to reenter inputs, see Example This time, try a length of 2. Reference: G. London: Institution of Chemical Engineers, The reactor is to be jacketed so that a high-temperature gas stream can supply the energy necessary for this endothermic reaction see Figure E Pure acetone enters the reactor at a temperature of K and the temperature of the external gas in the heat exchanger is constant at K.
The reactor consists of a bank of one thousand 1-in. Determine the temperature profile of the gas down the length of the reactor. Figure E The only chnage from the adiabatic example is in the Block input data. Run the simulation. In this example, the proper length was 1. The flowsheet and results are valuable documents verifying your work. The Flowsheet. Stream-by-Stream Results. To print the stream-by-stream results, follow steps 4 above while the results window is active.
The History File. Printing the history file of your process model will allow you to step through all of the computer code used in solving the simulation. Depending on the complexity of the process model, the history file can be very lengthy pages or more! Therefore, evaluate whether a hard copy of this file is necessary before you print.
To print the history file do the following:. If you wish to change the ID name, do the following:. Buckingham at the University of Michigan, Summer Anuj Hasija and Professor H. This section is a tutorial to walk you through Problem for the 1st edition of Essentials of Chemical Reaction Engineering. Normal butane, C 4 H 10 , is to be isomerized to isobutane in a plug-flow reactor. This elementary reversible reaction is to be carried out adiabatically in the liquid phase under high pressure using a liquid catalyst which gives a specific reaction rate of The feed enters at K.
The liquid catalyst is not included because its flowrate is not known and the specific reaction rate has been given for the reaction condition. These three components are called directly from built-in Aspen pure component databanks. Different property models can yield different predictions for various thermophysical properties used in mass and energy balance calculations. One of several equations-of-state well-known to be suitable for hydrocarbon systems, Peng-Robinson equation-of-state should provide reasonable calculations for heats of reaction and heat capacities.
The higher the temperature, the higher the heat capacity will be. Pressure also affects liquid heat capacity. The predictions here are done at 1 atm. The isomerization heat of reaction is also a function of temperature. The reaction stoichiometry is shown below:.
The forward reaction specific rate is Therefore, the above equation can be rewritten as follows. They are used to construct processes with proper feed streams and reactor conditions. Aspen requires input of reactor dimensions in lieu of reactor volume.
To start the simulation, initial values of 0. That gives reactor volume of 3. To start the simulation, initial value of 3 m 3 is assumed for the CSTR reactor volume. The study shows a reactor liquid volume of That corresponds to a residence time of to seconds, more than 6 times that of the RPLUG residence time. Given the models, various reactor analyses can be performed.
For example, a PFR reactor liquid volume of 1. Avertissez-moi par e-mail des nouveaux commentaires. Avertissez-moi par e-mail des nouveaux articles. Continual Improvement Process. Aspen Plus.

What can be modeled and simulated? There are a lot of processes which can be modeled! Hierarchy levels for given process Run, Re-Run, Reset, Pause, Stop Simulation as you see fit Input data directly or indirectly by re-writing the input windows of blocks and streams And much more! Where can I get access to it? What is Process Simulation?
Why do I prefer Aspen Plus? Is THE « standard » Whenever I talk about process simulation, most of people think about Aspen Plus, which is easier for me, as that is actually the software I use. Resources everywhere! What we can do is simply state several tips and best practices for learning. It is about Process Simulation and some of my tips 1 Directly from Aspen Tech You can find a lot of workshops, tutorials, support center and formal training here.
Advantage : This is one of the best ways to learn since they are literally the ones who created the software and know the best practices. Disadvantages : it is expensive and you need to have the contact already 2 In your University or Lab this is also pretty common, most students from bachelor level in chemical and process engineering will be taught some basics of the software on how to model several processes and basic unit operations.
Advantages : you get to work in teams, you get to relate a school project with a real life project. It is relatively cheap as you already paid for it in your tuition. Disadvantage : not really a formal training, depends strongly on your instructor and you might miss very important details on the software tools. Your instructor may not guide you into the best practices of the software, as it will 3 From a MENTOR I learnt directly from my boss and colleagues that have been using the software for decades.
Advantages : Direct and hands on to project. Disadvantages : They might not have enough time for you to actually explain you how to model things. Kinda hard to find mentors 4 Online — Courses There are plenty of courses online that will help you a lot, specially if you are staring from a newbie position. Advantages: At your pace, relatively cheap. You can get access to online tutor and instructors in some courses. These courses are a great way to pump up your knowledge for basic to intermediate levels.
Disadvantages: You are mostly on your own. Might be expensive. Typically, will not cover very specific type of simulations. Hard to find extensive offering specially in advanced topics polymers, biotech, electrolytes, etc.
One of the best channels for that is this one right here which has a good structured set of playlists … Advantages: At your pace, its for free. Many videos! Disadvantages: You are on your own. Some tutors will not explain at all.
Incomplete material. Hard to understand to certain accents. No formal introduction to the problem. Just work with them and try to make them work. Go out, try to simulate processes from the courses, youtube videos, or tutorials. They might be E-Books or Physical Books, whatever you choose, they will help you through this hard stage of life I have read several of them and here are my notes.
It is simple and straight to the point. Not so many unsteady state analysis No economic or financial analysis Does not explores the physical environment extensively The Ugly Expensive! This is based on Aspen Plus V8. If you want to learn more on simulation, this is NOT the book for you! How do you get HELP!? AspenTech « Help » Button This is, I think, the most straight forward approach whenever you have a doubt.
Reddit Forums I am a Reddit Fan! Having a Mentor will also help a lot! Simply ask! Also, not only the OP might answer you but other fellow mates will do See an example here. Fiverr Aaaaaand yes…. Most of them are related to other blog post so feel free to check them out! This saves us a lot of resources such as: time, money, human labor, material, etc… It also help us to design new processes, model existing ones and verify future existing scenarios. Make no worries, we will analyze the most common ones here!
There are two main types: paid and free. Where do you get access to AspenTech Software? How do licenses work? Saves human error! Aspen Plus vs. So, what is the difference? Or which one is the most convenient? Aspen Plus V Main Differences… Ok so there are of course many differences, so lets check the most relevant ones… This is not only technical, I checked for other fellow engineers opinions on what is the main difference between each other.
The GUI Graphical User Interphase As in any software, the graphical user interphase the visual stuff, buttons, structure, folders, overall organization, etc… is one of the most vital parts! Logical Operator Blocks Sometimes you will have a process which involves a specific set of Logical Operations.
Wrap up! Briefly, here are the programs and capabilities: Aspen Adsim — Fixed bed adsorption for pressure swing adsorption, etc. When you are prompted to connect to the engine license configure the window as shown, and click OK. Figure 2. Specification of Flowsheet in Aspen Plus If you are working with Aspen Properties, you may skip to section 4 of this document.
The first step is to choose the column type for the ethanol-water separation. Click on columns to view the different column simulations available. Figure 3. Next you have to add streams to the block. For this example, set up the feed stream: choose the Material stream by clicking on it.
The column will now show arrows where the stream can be connected; red arrows indicate required streams as shown in Figure 3. Now, move the mouse to the left and click again. You should now have a defined feed stream Stream 1. For the outlet streams click the column outlet first to connect the bottoms Stream 2 and liquid distillate Stream 3. If you make a mistake and want to delete a stream or block, click on the arrow select button at the upper left of the Model Library toolbar, then click on the stream or block you want to delete and hit the DELETE key.
Configuring Units and Settings In the Data Browser, you are required to enter information at locations where there are red semicircles. Specifying Components Here you have to enter all the components you are using in the simulation. The screen to select the property method is shown below. Understanding Aspen Binary Parameters The form of the thermodynamic model parameters usually differs from the form in the published literature because ASPEN often replaces parameters with functions of temperature.
Additional Features to Explore Thermodynamic Behavior 8. The diagram is displayed: When you close the diagram you will find the table with some intermediate calculations. The flowsheet also indicates all product streams. Each stream and unit operation is labeled and identified. Chemical Components The process model specifies all chemical components of the system from the necessary reactants and products, to steam and cooling water.
Operating Conditions All unit operations in the process model are kept under particular operating conditions i. These are usually at the discretion of the engineer, for it is the operating conditions of the process that effect the outcome of the system. If the installer asks you to specify the location of a file, click on Cancel and then again on Cancel in the Windows installer window. Check the Template box and select ok.
Then select the template you want to use from the Simulations tab and hit ok. Again a Windows Installer window will apear. Select Cancel if you are asked to specify the location of a file. At other universities please refer to the help desk at your computer site for the appropriate selection and information to connect to the simulation engine.
Your screen should look similar to the one below. Here is a summarized version of the problem: Example Determine the plug-flow reactor volume necessary to produce million pounds of ethylene a year from cracking a feed stream of pure ethane. Unit Operations The easiest way to create the flowsheet is to start with the Unit Operation and add the streams to it.
Along the bottom of the window there are several tabs with different types of equipment as labels. Click on the Reactors tab. For this example we are going to use RPlug Click on the RPlug button once and then click again on the blank process flowsheet. You will notice on the left of the different reactor buttons there is a down arrow wich brings up a pulldown menu. You can change the icon that appears on the process flow sheet from this menu. The icon affects only the appearence of the flowsheet.
You should now see an icon for a plug flow reactor on the process flow sheet. It will arbitrarily be named B1. Click on this button. When you move the cursor onto the process flowsheet you will see two red arrows and two blue arrows appear on the reactor. These arrows indicate places to attach streams to the reactor. Move the cursor over the red arrow at the top of the reactor. This is the feed stream. Click once when the arrow is highlighted and move your cursor so that the stream is in the position you want.
Then click once more. You should see a stream labled 1 entering the top of the reactor icon. At this point your screen should look something like this: To finish our flowsheet we need an outlet stream Outlet Product Streams You are now ready to add the outlet stream containing both ethylene and hydrogen to your flowsheet. Your screen should now look like this: Connecting the Streams to the Unit Operation If you did not connect the stream to the unit when you created the stream, you can still attatch it to the unit.
Double click on the end of the stream you wish to connect to the unit. Your mouse will now control the end of the stream. To attach the stream simply move the end of the stream over one of the red or blue arrows on the unit.
While the arrow is highlighted click once more and the stream will be attatched to the unit. Entering Process Conditions Now that the process flowsheet is complete, it is time to enter the process conditions. Click Next with the left mouse button. A window will prompt you that the flowsheet is complete and asks whether the next input form should be displayed.
As before you should cancel the Installer it may take several times before the Installer finally quits. The first input window will be called Setup Specifications. With the left mouse button, click once on the Title box to highlight it, enter the title of your process model. Check that the desired units are correct. You can change the units in the pull-down menu under Units of measurement. Click on the desired units. A should appear next to Specifications in the navigation window on the left.
Click Next. For this particular example, the components are: ethane, ethylene, and hydrogen. Start with the second to last column called Component name. Click on the first row in the column and type in: ethane. Hit Enter. From here you can search for the correct chemical. Notice how the molecular formula automatically appears after typing it in. Now click under Component ID. Enter an id name to show up in results for ethane, perhaps ETHA.
Repeat steps 5 and 6 for ethylene and hydrogen. Under « State variables » go to the menu that says Temperature. Enter and from the pulldown menu to the right of the entry select K for Kelvin. In the Pressure entry type 6 and select atm from the pulldown menu. Now look to the right and find the Composition table. Since ethane is the only component of the inlet stream, click in the box next to ETHA and enter 0. You start at the Specifications tab.
From the Reactor type pulldown menu select Reactor with specified temperature. In the Operating conditions section mark the first choice: Constant at inlet temperature Click Next Click in the Length box and enter a value.
Be sure the units are ft. Change the units accordingly via the pull down menu method if necessary. Do the same for the Diameter box. Be sure the units are in ft. You are solving this problem by guessing a volume. When you run the simulation you will see what conversion is achieved with the guessed volume.
Hit the next button. The will not show up yet The next window asks you to select a reaction set. However, you have not created a reaction set yet. From then navigation menu on the left, double click on the Reactions folder. Two subfolders will appear. Click on the Reactions subfolder. This is where you will specify the stoichiometry of the reaction occurring in the PFR. Hit ok. This takes you to the Stoichiometry tab. From here select New…. Now look at the balanced reaction equation in the problem statement.
The coefficient of ethane is 1 so enter 1 in the Coefficient box. Enter a 1 in the coefficient box. Then select H2 from the Component pulldown menu and enter 1 for the coefficient. Click on the Next button to close the window and again to advance to the next input. The reaction you just entered should be shown in the first pulldown menu.
Enter 0. Lastly, the rate law must be entered. To do this click on the Driving Force button to the right. Type 1 for the Exponent. Enter 0 for all four driving force constants A, B, C, D at the bottom of the window.
Since this was an elementary reaction and there is no second term enter 0 for all exponents and B, C, and D coefficients. This will make term 2 essentially 0, leaving us with the elementary rate law.
