Oxygen Purification

Overview of Oxygen Generation

Pressure Swing Adsorption (PSA) is widely used in air separation plants. PSA separation techniques tend to replace the traditional cryogenic air separation because of its low investment, low energy consumption, and easy operation. Oxygen and nitrogen are separated, and then oxygen or oxygen-enriched air is captured. This process occurs under the principle that molecular sieve for oxygen generation adsorbs nitrogen and oxygen at different rates in a certain pressure condition. Once separated, the oxygen stream can be used in various refining processes, as feed gas for pneumatic equipment, utilized for breathing oxygen, and for other industries that require high purity oxygen streams.

 

How Large Scale Oxygen Generation Works (Industrial Oxygen)

A compressor is used to intake air, which then passes through molecular sieve beds where oxygen is separated from nitrogen. These large scale units allow oxygen to be generated in high volumes, generally used in industrial applications. Once separated, oxygen can be liquefied and stored, used as feed gas, and more.

 

How Small Units Work (Medical Oxygen)

Molecular sieve is used to produce oxygen for use in or out of the home. A compressor is used to intake air from the surrounding environment, which is then processed in molecular sieve beds where nitrogen is removed. Oxygen is then pumped into the product tank, and the sieve bed is regenerated to allow the process to be repeated. The small size of these units require small beads to allow sufficient oxygen production, while remaining light enough for the user to carry.
