4. PSA PROCESS TECHNOLOGY

5. The air we breathe contains roughly 78% nitrogen, 21 % oxygen, .9% argon and the balance is other gases. The oxygen is separated from the air using PSA Technology. The process centers around a molecular sieve known as Zeolite. At high pressures the sieve adsorbs or attracts nitrogen, and at low pressures it desorbs or releases nitrogen. The On-Site generator consists of two tanks filled with sieve. As high pressure air (about 70 psi) is introduced into the first tank, it passes through the sieve and nitrogen is adsorbed. The remaining oxygen and argon are piped to a buffer or storage tank. Just before the first tank becomes completely saturated with nitrogen, feed air is redirected to the second tank which then repeats the above process. The first tank is then vented to atmosphere which allows the nitrogen to desorb or release from the sieve. To complete the regeneration of the first tank, a small amount of the oxygen is used to purge it. This process is completed over and over again until the demand for oxygen is met. Under normal operating conditions, which includes the use of clean dry air for separation, the sieve will last indefinitely.
