Natural Gas Sweetening Process with DEA || Aspen HYSYS

This video is about the simulation of the Natural Gas Sweetening Process with diethanolamine (DEA) in Aspen DEA. The major units of the process are:

1. Absorber
2. Distillation Column (Stripper)
3. Shell and tube heat exchanger
4. Set

Great Tutorial, Thanks again for your work sir ! Keep it Up as always.

The tutorial is straight forward and nice. But i am having issue with my overhead product at the stripping section. Methane and water compositions are higher than CO2. What can i do to resolve the issue please?

Hello
Thanks for your tutorial.

I do the same as you show, but my absorber does not converge, it gives the error named : ' Fatal Error : Zero Diagonal in Column Matrix", do you have any suggestions ? Thanks

I have done this simulation as a part of my project, can you please tell me from where is the simulation data collected from.

Hi, pls are you familiar with DWSIM process software? Serves similar purpose as Aspen. However, I am running into challenges with the Absorption column pressure. There’s only room for a single operating pressure as opposed to Aspen where we have the top and bottom pressure. Pls any help?

[shoaibarshad]

How do you calculate absorber and stripper stages?

[laxmareddy]

What is the purpose of the saturator before absorbtion?

[uswatunkhasanah]

can you make a video explaining the process, I got an assignment from my lecturer. please 🙏

I don't know why but the DC didn't nucleate. Followed your procedure but it is taking unnecsessary long to solve.
