Consultation about pressure swing adsorption

[zasddsgg]

Hello, I am building a process to produce biodiesel from hydrocracking heavy oil (obtained by hydrothermal liquefaction treatment of kitchen waste), which requires pressure swing adsorption (PSA) to recover hydrogen, but there seems to be no PSA unit found in BioSTEAM (https://github.com/BioSTEAMDevelopmentGroup/biosteam/tree/master/biosteam/units). May I ask how to call PSA unit in BioSTEAM? Thanks for your help.

@yoelcortes Hello, could I consult you how do I call the PSA unit in BioSTEAM. I need to recover hydrogen from the hydrocracked gas after hydrothermal liquefaction treatment of kitchen waste. PSA doesn't seem to be in the tutorial (https://biosteam.readthedocs.io/en/latest/API/units/index.html) or the code (https://github.com/BioSTEAMDevelopmentGroup/biosteam/tree/master/biosteam/units).

I'm not sure if there's a PSA in BioSTEAM, but there's one PSA-related unit in QSDsan: https://github.com/QSD-Group/QSDsan/blob/main/qsdsan/sanunits/_hydroprocessing.py

The HTL system uses it: https://github.com/QSD-Group/EXPOsan/blob/pfas/exposan/htl/systems.py

Thank you for your answer, may I ask you how to call the PSA unit of QSDsan in BioSTEAM. Because I didn't find the PSA unit in BioSTEAM.
