          literature [0.7-0.13] and  expert  programs for  gas  separation  process design
          [0.20], [0.21].

             The gas separation  process  itself can  be based  on one or  more of the
          following physical effects:


             a)    mixture  adsorption  equilibria,  i. e. one  component is much more
                   adsorbed than all the others [0.1, 0.19];
             b)    adsorption kinetic effects, i.  e. one component is diffusing much
                   faster within the adsorption material than all the others [0.20];
             c)    molecular  sieve  effects, i. e.  steric  effects of  bulky  molecules
                   preventing them from entering a pore (system) [0.21];
             d)    quantum sieve effects in so-called nanopores. This effect is only of
                   importance for separating hydrogen or deuterium from other gases
