Separation of CO2 from Flue Gases using Absorber in Aspen HYSYS - Lecture # 22
ฝัง
- เผยแพร่เมื่อ 5 ต.ค. 2024
- Learn to simulate the Absorber in Aspen HYSYS for the removal of CO2 from the flue gases. The separation of CO2 is linked with greenhouse gases emissions (GHG) i.e., the lower the CO2, the lesser will be the GHG.
Please do watch, like, and share the video, and subscribe the channel.
Problem Statement:
1. Flue Gas: (65 °C, 1.5 bar, 1000 kg/h, 70 mol% nitrogen, 15 mol% water, 10 mol% CO2, 5 mol% oxygen).
2. Solvent (25 °C, 1.2 bar, 3800 kg/h, 25 wt. % MDEA, 75 wt. % water).
3. Absorber (50 stages, Top pressure: 1.2 bar, Bottom pressure: 1.5 bar)
4. Achieve 81% separation.

thank you for saving my life...
Please, Is it possible to define the properties of flue gas directly in aspen plus?
Awsm video sir...I clearly understand your simulation sir.... thanks
Thank you Dibakar.
I didn't understand why you added H2S and H2O2?
How can u recover the Co2 to recycle it for a syngas production plant
(For a lower H2/Co ratio)
Sir! can you make a tutorial on the pyrolysis of biomass.
Can you please share the name of any reference material or book where I can find more detailed explanations of hysys features?
wow sir great this is in my FYDP
can you share the aspen hysis set up link here
Can we make a hybrid model with absorber and membrane??
Successfully completed lec 22
Is this model simulation applicable for cement industry ?
Aspen Plus can be used to model the processes in the cement industry
very nice, thanks
Very detailed.
Thanks for this
I have a flue gas of Nitrogen, CO2, water vapor and sulphur dioxide.. how do I absorb only CO2 into water.
Thank you bro very clear
Please Sir, the 81% separation achieved is based on what precisely?
Is it dependent on the input parameter or is there a way we can upscale the % to let's say 92%?
Good question, same is my question.
I'll appreciate your kind response
Yes, it can be upscaled, because it's a shortcut design. The separation is achieved because of input in the shortcut column. I hope that addresses your query.

@@aspenchemchannel that means we can upscale in rigorous design of absorber?
Yes.
Hi, how can you know the percentage of flooding of the column?
For this, hydraulic design is required for the system, which is presented in Lecture # 21 on Aspen HYSYS, and Lecture # 55 on Aspen Plus.
Is Vaccum pump design in Aspen hysys?
What can I do if majority of the N2 and O2 are exiting at the bottom ?
This methode can separate CO2 from H2
Can you please show operation of Flue gas desulpharizer using limestone slurry?
I will try to cover in the upcoming video.
Hi! Is it possible for the flue gas to contain water at 65 C? Won’t it be in liquid form? Thanks
how we can replace package property of acid gas to another property because in my hysys software there is no this property
You can use Acid gas, in case of older version, and in latest version, can use the package described in the video.
@@aspenchemchannel Sorry, but you used the acid gas property packag how I can replace this property with another property
Just click on other property package, and it will be selected.
@@aspenchemchannel I did not understand please help me
When you click on e.g., Peng-Robinson, then it gets selected. Right? Similarly, if you want to change to SRK, then click on SRK property package, and it will be selected.
I have gas flow in nm3/hr how to feed it in material stream?
Its a volumetric flowrate. Instead of specifying molar flow, specify volumetric flow
@@aspenchemchannel thanks for replying
Hi Dr. Muhammad Haris, Is it possible to design a membrane using ASPEN HYSYS to separate CO2 from a gaseous mixture.
Hi Dithin. Unfortunately, it is not possible yet.
@@aspenchemchannel ok sir. Thank for the update.
Plzz tell me just with which another property package i can do this simulation ? I DON'T HAVE "acid gaz" nor "other property"
Plz answer me i really need it
watch it ....how select property package th-cam.com/video/n1OVoMXJKZY/w-d-xo.html
Excuse me sir, can we do this in Aspen Plus, or do you have a video for it? Also, what is the preferred method for it please? like SRK or Peng-Robinson? Thank you very much
Yes. We can do this in Aspen Plus. I haven't made video on it yet. The property package selected in the video will remain the same.
@@aspenchemchannel sir I did one and it worked. So I used the Elec Wizard and method ENRTL-RK to design the CO2 desorption system. The reboiler duty is around 6.13-13 kW and I set my reflux ratio to somewhere 0.5-0.8. Then to reverse the reaction and recover MEA, I had a flask to act as a condenser and reduce the temp at the vapor outlet of the desorber (rad frac, 2 stages). The recycle has a purge like 0.02 and then add a makeup for MEA solution. Also to mention I have a 0.3wt% solution of MEA. Thanks for the video again sir, it gave me an idea where to start!
Can i get its model file so i run it directly
hi, can you make a video for ethylene/ethane separation by Ba-ETS-4 by adsorption Aspen HYSYS
Adsorption is not possible in Aspen Hysys. The phenomena of adsorption can only be depicted by using component splitter, a short cut method.
What can i use instead "acid gas"?? I have the old hysys
Is it ok if i do it with peng robinson ?
Yes. Acid gas in previous versions. No, peng robinson cannot be used, as it's an amine process.
I don't have this property package in my hysys, what should i use ?

is it possible to model a membrane seperation in aspen
Yes. However, first the model should be prepared in the Aspen Custom Modeler, and then imported to Aspen Plus.
Is it possible with NRTL ??
NRTL means non-random two liquids. So, as per definition, and obviously looking at the model, this property package cannot be used.
@@aspenchemchannel in my hysys there's no "acid gas" not even "other property" so i can't do this simulation ??
Are there any alternatives to AspenHYSYS or any free trial for this software?
This software is available free of cost.
@@aspenchemchannel Where can I get this software? I didn't see any download link from the website.

@@aspenchemchannel ohh. this is really bad for Aspen tech since this tool is available free of cost.
