All living being need oxygen for respiration, without which it is impossible to stay alive. When we breathe oxygen it is absorbed by the blood stream in the lungs which then travels to the cells where a lot bio-chemical changes take place. It is said that the living cell is the location for tremendous bio-chemical activity simply known as metabolism. Nutrient compounds found inside the cells are oxidized through enzymatic processes. This oxidation generates energy and heat for all living beings. And, we need adequate level of oxygen for supporting cellular respiration. Individuals not getting adequate level of oxygen need to take supplemental oxygen. PSA medical oxygen plant is used for generating medical grade oxygen.
Specifications for medical grade oxygen
Medical oxygen must meet certain specifications like its purity must be above 99.7% besides complying with the standards of Indian and European Pharmacopeia. It must also meet the specifications of identification, Odor, CO2 not more than 0.03% and CO not more than 0.001% in gas. Individual afflicted with various conditions such as COPD, cyanosis, shock, severe hemorrhage, carbon monoxide poisoning, major trauma, cardiac/respiratory arrest, etc, have to breathe extra medical grade oxygen in order to go through their daily activities. Oxygen plant in hospitals should be built as internationally approved standards such as ASME, ANSI, NEMA and CE.
Production of medical oxygen gas by plant
Medical oxygen plant taps atmospheric air which is compressed in the air compressor before being sent into a cleanup system where impurities such as carbon dioxide, hydrocarbons and moisture are removed. Then, air goes into a heat exchanger where oxygen is cooled into a cryogenic liquid. Then, it is introduced into a high pressure distillation column where oxygen is separated from nitrogen and other gases. Thereafter, it is distilled continuously till it meets medical specifications.
