Adsorption process for recovering adsorbable components from a multicomponent gas stream
A cyclic adsorption process is provided for recovering adsorbable components from a multicomponent inlet gas stream. One or more of a number of fixed beds of solid adsorbent are contacted with the inlet gas stream so that adsorbable components are adsorbed. Simultaneously, one or more other beds are contacted with a heated regeneration gas stream so that previously adsorbed components are desorbed therefrom into the regeneration gas stream and recovered, one or more additional beds are contacted with a cooling gas stream so that the bed or beds are cooled. The flow patterns of the inlet gas stream, the regeneration gas stream, and the cooling gas stream are continuously changed or cycled. Each of the beds is periodically contacted with a second heated regeneration gas stream so that previously adsorbed components which are difficult to regenerate are desorbed into the second regeneration gas stream and recovered, thereby preventing the buildup of difficult-to-regenerate components on the beds.
