Title: Pressure swing adsorption process used for recovery of oxygen from air includes adding or removing gas through the inlet of an adsorption bed
Inventor: HOFMANN ULRICH
IPC: B01D53/047
Filed: 1999-08-28
Granted: 2001-01-11
Abstract: During the process steps (a) to (e) of the process cycle air is added or gas removed through the inlet of the adsorption bed (6) by using ventilator device (3). In one-bed-pressure swing adsorption process for recovery of oxygen from air,  (a) ventilator air is passed into an inlet end of a single adsorption bed (6) which consists of zeolitic molecular sieve material, where nitrogen is adsorbed as the stronger adsorbable component of air, in which the pressure of the adsorption bed (6) lying below atmospheric pressure is raised to a first intermediate pressure lying above atmospheric pressure, and oxygen as the weaker adsorbable component of air is feed from the product end of adsorber bed (6) to a product tank (8), at pressures which are approximately the same as the adsorption pressure; (b) the adsorber bed (6) in the same stream is released into a second intermediate pressure which is higher than the first intermediate pressure, releasing from void volume gas of the product end of the adsorber bed (6), the void volume gas is feed to a pressure receiving tank (7); (c) the adsorber bed (6) in the same stream is released from the second intermediate pressure to lower desorption pressure which lies below atmospheric pressure, where additional amount of gas is released from the inlet end of the adsorber bed (6); (d) an oxygen product gas side stream is fed from the product tank (8) to the product end of the adsorber bed (6) as rinsing gas, in order to displace desorbed nitrogen from the void volume in the adsorber bed (6) at the lower desorption pressure, where the displaced nitrogen is released from the inlet end of the adsorber bed (6); (e) void volume gas is fed to the pressure receiving tank (7) to the product end of the adsorber bed (6), in order to raise the pressure of the adsorber bed (6) from the lower desorption pressure to the first intermediate pressure; (f) during release of the adsorber bed after step (b), ventilator air is simultaneously added to the inlet end of the adsorber bed (6) by means of ventilator device (3); (g) complete pressure equalization occurs between the adsorber bed (6) and the pressure receiving tank (7); (h) reverse stream release of the adsorber bed (6) after step (d) is carried out using gas stream from the product end of the adsorber bed (6); (i) pressure build-up occurs in the adsorber bed (6)  with an oxygen product side stream from the product end of the adsorber bed; (j) during the pressure build-up in the adsorber bed the ventilator air is fed into the inlet end of the adsorber bed using the ventilator; and (k) to build-up pressure in the adsorber bed an additional air stream is utilized as a driving force when there is a pressure drop between the surrounding environment and evacuated adsorber bed.  An Independent claim is included for pressure swing adsorption system.
