Adsorption & Membrane Separation
PSA, the real cyclic transient
A genuine 2-bed pressure swing adsorption cycle — one bed adsorbing while the other regenerates, swept countercurrently by product — solved to a periodic steady state, not an assumed recovery fraction.
Process modules
Pressure Swing Adsorption (PSA) Hydrogen Purification
A shift-gas feed purified across a real cyclic 2-bed PSA — competitive-Langmuir equilibrium and linear-driving-force kinetics to a periodic steady state.
Open process page →VPSA Oxygen Generation
Air fed into a real 4-bed vacuum pressure swing adsorption unit — the same 2-bed engine generalized with pressure-equalization steps and sub-atmospheric evacuation.
Open process page →Gas-permeation membrane separation and temperature-swing adsorption (TSA) aren't modeled yet — the membrane unit op we ship today is a liquid reverse-osmosis rating model, not a gas-separation membrane.
