Amid the ongoing COVID-19 crisis, the planning for the management of oxygen generation with the right equipment for the right time is vital to a hospital or alternate medical care application. To avoid on the dependency of the oxygen cylinders from outside, the hospitals all across the globe look for onsite oxygen generation and have already implemented the change to produce their own medical Oxygen Onsite. Medical Oxygen Generators produce gaseous oxygen from compressed air on site and offer a cost-effective, reliable and safe alternative to traditional oxygen gas supplies such as cylinders or cryogenic liquid.
For, the industry, worth over $2 billion in India, is producing nearly 7,800MTPD of oxygen, while demand has risen to 5,500-5,800 MTPD now. Traditionally Oxygen in Medical field has been used from cylinders or from liquid tank. The biggest problem with gases — such as oxygen — is transportation. However, since 1970, PSA Oxygen generators have come in use for Medical Oxygen gas. These greatly reduce capital cost and offer mobility for requirement of hospitals and health care sector. Because Oxygen has traditionally been delivered from cryogenic sources, the medical Oxygen specified that purity had to be greater than 99 per cent. However, extensive clinical trials led to conclusion that 93 ± 3% Oxygen from PSA Oxygen generator presented no physiological effect on patients and therefore, now Oxygen generated by PSA generators is acceptable for use and is recognized and permitted by USA, European and Indian Pharmacopeia.
Air contains 21% Oxygen, 78% Nitrogen, 0.9% Argon and 0.1% other trace gases. NAMO An Oxygen generator separates this oxygen from Compressed Air through a unique process called Pressure Swing Adsorption(PSA). The Pressure Swing Adsorption process for the generation of enriched oxygen gas from ambient air utilises the ability of a synthetic Zeolite Molecular Sieve to absorb mainly nitrogen. While nitrogen concentrates in the pore system of the Zeolite, Oxygen Gas is produced as a product. NAMO Oxygen generation plant’s use two vessels filled with Zeolite Molecular sieve as adsorbers. As Compressed Air passes up through one of the adsorbers, the molecular sieve selectively adsorbs the Nitrogen. This then allows the remaining Oxygen to pass on up through the adsorber and exit as a product gas. When the adsorber becomes saturated with Nitrogen the inlet airflow is switched to the second adsorber. The first adsorber is regenerated by desorbing nitrogen through depressurisation and purging it with some of the product oxygen. The cycle is then repeated and the pressure is continually swinging between a higher level at adsorption (Production) and a lower level at desorption (Regeneration).
