Green Hydrogen Recovery from Natural Gas Grids by Vacuum Pressure Swing Adsorption [PDF]
Industrial & Engineering Chemistry ResearchThis study focuses on the development of a conceptual vacuum pressure swing adsorption process (VPSA) for green hydrogen (GH) recovery from natural gas grids (NGGs). Accordingly, the kinetics-based separation of H-2 from NGG was achieved by using a commercial carbon molecular sieve (CMS-3K-172) adsorbent.

Dual-stage vacuum pressure swing adsorption for green hydrogen recovery from natural gas grids
Separation and Purification TechnologyPurification of green hydrogen (GH) from natural gas grids (NGG) can be expensive and challenging through a single-step Pressure Swing Adsorption (PSA) process due to the low H2 concentration in the grid (99 % v/v). A mathematical model is developed in Aspen adsorption, where numerical simulations are performed to establish the best operating ...
