Abstract (EN): Pressurization of adsorption beds with pure inert gas, a mixture of inert gases and a binary mixture of inert and adsorbable gases is studied. Modelling of pressurization involves mass and momentum balance equations. Linear equilibrium between adsorbed phase concentration and gas phase concentration inside pores for the active species is assumed. Model equations are numerically solved by collocation on finite elements. The importance of axial pressure gradients is assessed. Numerical simulations provide information on pressurization time, penetration distance and their relation with operating conditions. © 1991.
