Abstract
A pressure swing adsorption process for separation of gas mixtures that contain components with different adsorbing characteristics is disclosed which process includes providing an adsorption apparatus having a plurality of beds and counter- currently purging at least two of the beds simultaneously throughout the process. The number of beds and number of pressure equalization steps are not particularly limited, but a ten-bed, four pressure equalization step process is advantageous. In addition, other ten-bed, four pressure equalization step processes are disclosed which do not counter-currently purge at least two of the beds simultaneously, but which have an average of at least two of the ten beds being simultaneously regenerated by simultaneously providing off-gas from a feed end of each of the two beds to an off-gas line.
