Abstract
A method using pressure adsorption techniques for separating individual gas components from gas mixtures on adsorption agents in which a gas mixture is fed under increased pressure onto and in contact with an adsorption agent layer maintained in a separation reactor wherein undesirable gas components are adsorbed and thereafter the product gas is discharged so that a subsequent build up of pressure to adsorption pressure takes place in the layer by gas flow in reverse direction with respect to the adsorption direction followed by a subsequent adsorption stage wherein in accordance with the invention the pressure relief and rinsing action are caused to occur in two stages using reverse direction of slow with respect to the direction of adsorption; the relief gas obtained from the first reverse flow pressure relief stage is used as a rinsing gas for the first rinsing stage; the relief gas obtained from the second reverse flow pressure relief stage is discharged as a remainder gas and the product gas is used as a rinsing gas for the second rinsing stage.
