Oxygen Generation

oxygen generators extract the available oxygen in the ambient air from the other gases by applying the Pressure Swing Adsorption (PSA) technology. During the PSA process compressed, cleaned ambient air is passed through a molecular sieve bed as an adsorption bed. The special structure of molecular sieves allows the passage of oxygen through the adsorption bed while adsorbing other gases in the air. The sieve releases the adsorbed gases to the atmosphere when the outlet valve is closed and the bed pressure returns to ambient pressure. Subsequently, the bed will be purged with oxygen before fresh compressed air will enter for a new production cycle.

There are two types of oxygen concentrators that are classified according to their application:

Portable Oxygen Generator:

Oxygen concentrators filter surrounding air, compressing it to the required density and then delivering purified medical grade oxygen into a pulse-dose delivery system or continuous stream system to the patient. It’s also equipped with special filters and sieve beds which help remove Nitrogen from the air to ensure delivery of completely purified oxygen to the patient.

LTX Molecular Sieve

LTX molecular sieve is a specialized 13X molecular sieve for effective oxygen generation in medical and industrial PSA systems. According to exceptional nitrogen capacity, extraordinary kinetics and superior selectivity, molecular sieve LTX can produce oxygen-rich streams with a purity exceeding 95% in stationary and portable oxygen concentrators

Industrial Oxygen Concentrator

Industrial processes may use much higher pressures and flows than medical units. Non-medical oxygen concentrators can be used as feed gas to a medical oxygen system, such as the oxygen system in a hospital and additional filtering is generally required.

13X Molecular Sieve

13X is a sodium type molecular sieve with 10-angstrom pore diameter. It’s widely used for sweetening, dehydration as well as PSA systems. 13X molecular sieve has high N2/O2 selectivity. In the oxygen generation process, it will adsorb nitrogen from the air and purified oxygen up to 90%.
