Pressure Swing Adsorption technology for nitrogen generator
The technology of air-to-nitrogen production with the use of adsorption processes in nitrogen generators is well studied and widely applied at industrial facilities for the recovery of high-purity nitrogen.
The operating principle of a nitrogen generator utilizing the adsorption technology is based upon the dependence of the adsorption rates featured by various gas mixture components upon pressure and temperature factors. Among nitrogen adsorption plants of various types, pressure swing adsorption (PSA) plants have found the broadest application world-wide.
The system's design is based on the regulation of gas adsorption and adsorbent regeneration by means of changing pressures in two adsorber-adsorbent-containing vessels. This process requires constant temperature, close to ambient. With this process, nitrogen is produced by the plant at the above-atmospheric pressure, while the adsorbent regeneration is accomplished at below-atmospheric pressure.
The swing adsorption process in each of the two adsorbers consists of two stages running for a few minutes. At the adsorption stage Oxygen, H2O and CO2 molecules diffuse into the pore structure of the adsorbent whilst the nitrogen molecules are allowed to travel through the adsorber-adsorbent-containing vessel. At the regeneration stage the adsorbed components are released from the adsorbent vented into the atmosphere. The process is then multiply repeated.
How PSA Nitrogen Generation Works
Adsorption is the physical process of separating molecules. Our Pressure Swing Adsorption (PSA) systems generate nitrogen, by separating it from the oxygen in ordinary air.
A vessel containing carbon molecular sieve, or CMS, is filled with compressed air. The smaller oxygen molecules are adsorbed by the sieve material while the larger nitrogen molecules drift past and are collected in a nitrogen receiver.
Pressure is then released from the vessel, and the oxygen molecules are vented to the atmosphere. At the same time, the cycle is repeated in a second vessel to provide a flow of gas into the nitrogen receiver.
