Abstract
A gas mixture separator having adsorbent (1) with pressure dependent adsorptivity includes a cylinder (2) and a piston (3) as a means of pressure modulation necessary for the adsorption and desorption of gas components to be separated. Ingredient gas to be separated is fed to the cylinder through an inlet valve and inlet (5) to flow into contact with the adsorbent (1) by pressure produced by the piston (3) moving toward top dead center in the cylinder (2). The unadsorbed gas component passes through the adsorbent and exits the cylinder through the outlet (4) and associated outlet valve. The adsorbed gas component is desorbed during depressurization of the cylinder (2) during the retraction stroke of the piston (3) and exits through the outlets (8, 6) therefore. Adsorbed gas is introduced into the cylinder (2) through an inlet (7) therefrom from an additional separator for recovery of energy therefrom. A plurality of separators having the same construction (11a, b, c, d), are connected in a cascade arrangement for more economical operation with the adsorbed gas outlets (8 a, b, c, d) connected to adsorbed gas inlets (7a, b, c, d) of other separators. Along with a size reduction and …
