    5. Typical performance of nitrogen kinetic PSAs

    Compared to H 2 PSAs, which work mainly at adsorption equilibrium, N 2 PSAs are purification units that take advantage of the differences in diffusion rates between oxygen molecules (fast), and nitrogen molecules (slower) . A carbonaceous molecular sieve (CMS), with calibrated pore size, is generally employed for this separation. Compared with standard activated carbon, whose pore structure is organized around 1 nm, CMS are characterized by a high proportion of...
