Full CO2-MEA capture process with rate-base packed columns and kinetic reactions. Software by Aspen Tech Inc.; the template for this simulation can be found within the examples folder coming with any Aspen Plus installation. Alternatively, one may set up a new simulation including: a) the components found in this video, b) the ENRTL-RK model and c) Henry Constants as listed - in this case, the thermodynamic description of the system is going to be different.

Thank you so much for your dedication to teaching and for sharing your expertise with us.
1-Would you mind clarifying if the Aspen Tech template for MEA+Co2 is being utilized in your process?
2-I'm interested in understanding the procedure for creating the flowsheet independently. Specifically, in the properties section, under Parameters, then Pure Component, as shown in the video, how should one proceed? It appears that in the video, all sources such as CPAQ0-1 or CPIG-1 are defined by the user.
3-Could you please elaborate on whether you have made modifications to the ENRTL method, particularly concerning the vapor Eos? I noticed it is referenced as ESPSAFT, but in the ENRTL modified by Aspen, it is labeled as ESRK.
Thank you for your video. I did the simulation using the aspen templates. I received the following errors, could you please help me?:
***SEVERE ERROR
A LIQUID FEED/PUMPAROUND TO THE TOP STAGE IS REQUIRED WHEN
'Q1=0' IS SPECIFIED IN 'COL-SPECS'; REQUIRED FEED/PUMPAROUND
HAS ZERO FLOW.
***SEVERE ERROR
A VAPOR FEED/PUMPAROUND TO THE BOTTOM STAGE IS REQUIRED WHEN
'QN=0' IS SPECIFIED IN 'COL-SPECS'; REQUIRED FEED/PUMPAROUND
HAS ZERO FLOW.
* WARNING
REST OF BLOCK BYPASSED DUE TO SEVERE ERROR.
** ERROR
BLOCK B1-ABS IS NOT IN MASS BALANCE:
MASS INLET FLOW = 0.65361787E-01, MASS OUTLET FLOW = 0.65923066E-01
RELATIVE DIFFERENCE = 0.85872646E-02
And thank you for the video, it is actually pretty good!
Sir I have another question.. if we want to monitor Solvents behavior at different concentrations.. do I need to adjust the molar fraction at stream lean amine? Or which one do I need to control.?And how do I execute the graph for different concentration of amine?
Hello ! Thank you for the tutorials. Please, may i download them?
It would be very nice if you could add english subtitles!
@antonio Triodi sir please upload this video in the English version. it is very difficult to understand also need this pdf file
i could not understand at the 9 mins. would you please tell me , how to evaluate and insert data on temperature-dependent correlation parameter values (pure components tab)
In the video I didn't actually modify anything.
I just opened the tabs to show where things can be modified, if one needed to do it.
Dear Sir Can you please provide me the aspen file for this system? I have made some changes here in my original file and I cannot locate the error at the moment.
ciao, mi fa errore con '***SEVERE ERROR
COLUMN NOT IN MASS BALANCE.
CHECK FEEDS, PRODUCTS, AND COL-SPECS SKWS.'
puoi aiutarmi?
ho seguito tutti gli step
Ciao.
Prova in prima battuta a far convergere le collone a riciclo aperto. Se non funzionano nemmeno così, la prima cosa da controllare è il rapporto liquidi/vapore.
Hello. Is it possible to acquire the file which explains how to set up a CO2 capture with MEA simulation? It would be very helpful for my post grad. Thank you.
hallo. you can find the template in the Aspen plus installation folder under gui/examples (or a similar Path). notice that, for this tutorial, i have made some modifications in the "properties" section, and I rebuilt from scratch the "simulation" section.
if you Need further info you can email me peivately
@Juan REDON BARAHONA The template is located in the Aspen Plus installation folder, under /gui/examples (the exact path depends on your version). You will find some more chemical that I didn't use (sulfidric acid) and also different unit operation blocks, because the process scale is different.
@Juan REDON BARAHONA In this case, I left the values already compiled in the aspen tech template, and I show up the table only to specify where you can do modifications in case is needed. If you check out my tutorial on "extractive distillation", you'll see an example of how to compile that datsheet with alternative values.
Hye sir, can you share the specification for all property sets,, CONG, CPIG,..etc
Hallo.
You just have to pick up the CO2-MEA template in the aspen tech installation folder (C:\programs\Aspen Tech\Aspen Plus\GUI\Examples);
then go to the properties environment
select the component list
click the "review" button
@@Antonio_Tripodi thanks sir antonio
Can you make this video in English please
Hi Antonio, hope you are well. I have a problem before run the simulation. I followed all the steps but when I'm going to run it says that I'm forgeting information in the Flowsheeting Options and MEAMU and WATERMU balances appear. Can you help me please? This is for my University Project. Thanks a lot!
Try to use the 'next' button and let aspen tell you what is missing (red-white signal)
@@Antonio_Tripodi thank you! And Could you share me the book? It could help me a lot, I really need it to complete the bachelor's work
what did you end up inputting for the MEAMU and WATERMU balances ?
Did you solve your problem? I have a trouble same as you.
Was the problem resolved? I am encountering the same issue.
Hi sir could you please give me the link of the article because I need more information very urgent please 🙏
full descriprion of the book is at time 3:00
@@Antonio_Tripodi thank you so much sir but i just have problem in binary interaction almost of the parametre are not verfied( with blue tik) and also in eletrolyte pair thanks one more
@@gmarknis377 my advice is to start from the aspen tech template (see video for file location)
Buonasera, posso chiederle i valori delle costanti cinetiche delle reazioni 6-7? Nel video si vedono solo quelle delle reazioni 4-5 e non riesco a trovare dei valori online. Grazie
Salve. stai usando il file-base della aspen tech o stai partendo da un file bianco?
@@Antonio_Tripodi Sto partendo da un file bianco

Hi :)
I got a question after watching your video.
We're just copying your video to simulate the MEA process that's already in Aspen.
But there are errors in the mass balance😂
Can you tell me the solution?
No.
You're not following the correct approach.
First, you have to gather reference about your plant size and layout and solvent.
Second, you look up the aspen tech instalaltion folder for templates using that solvent.
Third, you validate the absorber column.
Fourth, you build the process.
"Copying my video", or "to simulate something that's are already there" is just pointless.
@@Antonio_Tripodi
Thank you for your answer.
There seems to be some misunderstanding about the question.
We copied your video for just ASPEN PLUS simulation learning, not process simulation.
Therefore, there is no information about mass balance and driving conditions because we do not have our own process.
We must succeed in the Aspen simulation. Could you tell me the information of the MEA and the water mass balance and the pump between the absorption tower and the heat exchanger?
@@heeso_0908 are you talking about the "mass balance" dedicated calculator , or in general?
Is your loop closed or open?
@@Antonio_Tripodi I want to know the mass balance in general. Our process loop is closed. Because we are "just following" the process in your video. It's exactly the same as your process!
How can I contact you?

Hi Antonio. Thank you very much. I am getting this error "SEVERE ERROR IN PHYSICAL PROPERTY SYSTEM WHILE PERFORMING INITIAL ENTHALPY CALCULATIONS FOR STREAM: "LEANSOL" (My lean amine stream) AQUEOUS FREE ENERGY OF FORMATION (DGAQFM/DGAQHG) MISSING FOR COMPONENT "MEAH+". UNABLE TO CALCULATE REACTION CONSTANT" I would appreciate any help. Thanks
Did you started from the Aspen Tech template for MEA-CO2, or did you build a complete new flowsheet from the scratch?
@@Antonio_Tripodi I did not use the template. I built a new flowsheet
I suggest to start from the template, because otherwise the procedure to set up the "properties" section is lentghy.
Nevertheless, these would be the steps to follow:
1) compile the components list using: CO2, N2, (or the other gases in your process stream), H2O, MEA;
2) use the "electrolyte wizard" to generates the electrolytes and the equilibria stemming from the chemicals; set up with the ELEC-NRTL model (and possibly henry constant for CO2);
3) be sure that "pair interaction" forms are compiled, possibly review the H2O-CO2-MEA vapor-liquid equilibrium against literature data;
4) review the H2O-CO2-MEA densities and viscosities against lit data;
5) create a new 'reactions-id' using the "distillation" or "power law" type for the MEA-CO2 reaction: if you're not using the template, also these reactions must be searched in the literature.
