There are numerous techniques for generating oxygen for hospitals including cryogenic distillation and pressure swing adsorption. We manufacture cryogenic air separation plants for generating oxygen for hospitals. The air separation unit (ASUs) taps atmospheric air for liquefaction for generating high purity oxygen. The air is compressed after it is let into the ASU and is sent into the cleanup system where impurities like hydrocarbons, carbon dioxide and water vapors. In order to cool the process air to cryogenic temperature, it is passed through the heat exchangers. After being cryogenically cooled, the air is let into the high pressure distillation column where oxygen is physical separated from nitrogen and other gases. Vaporous type liquid oxygen is formed at the top of the column from where it is collected and moved into a low pressure distillation column where it further distilled to meet specification for hospital applications.
In order to ensure that oxygen meets the purity standards of hospitals we run very stringent testing on oxygen purity in our plant machinery. Specifications of identification, odor, CO2 not more than 0.03% and CO not more than 0.001% in gas are strictly followed.
How is oxygen made for hospitals?
Oxygen is a vital element for biological and industrial purposes. There is no denying that the fact that life cannot survive on the planet without oxygen. Hospitals require oxygen for maintaining and aiding biological processes and its importance cannot be over-emphasized. Hospitals use commercially produced oxygen for medical applications such as COPD, cyanosis, cardiac arrest, carbon monoxide poisoning, inhalation, major trauma, resuscitation, respiratory arrest, shock, severe hemorrhage, etc. Oxygen used for medical purposes must meet certain specifications. It is imperative that oxygen made for hospitals must have purity 99.7% and should be generated in compliance with the standards of Indian and European Pharmacopeia.
