what is Oxygen ?
OXYGEN is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element and oxidizing agent that readily forms compounds (notably oxides) with most elements.
Uses of Oxygen
Oxygen is used in hospitals for killing bacteria. It is also used when a patient has had carbon monoxide poisoning and water treatment to purify the water to make it safe for us to drink and etc.Production of gas
Pure oxygen can be produced in several ways. In nature, plants produce oxygen by using sunlight, carbon dioxide (another gas) and water. This process is called photosynthesis. Most of the oxygen in the air is produced by photosynthesis. Oxygen can also be created by humans by technologies. There are many Production technologies for Oxygen Production likeOxygen Generator

How High Purity Oxygen Pressure Swing Absorption Generators work
Air contains 21% Oxygen, 78% Nitrogen, 0.9% Argon and 0.1% other trace gases. Oxygen generation systems separate 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.This process is based on the fact that different gases have the propensity to be attracted to different solid surfaces more or less strongly. This happens with the nitrogen, which is attracted to the zeolites. As the air is compressed, the nitrogen is forced into the crystalline cages of the zeolite, and the oxygen and nitrogen is less adsorbed and conveyed to the end of the zeolite bed and ultimately recovered in the oxygen buffer tank. Two zeolite beds are used together: One filters air under pressure until it gets saturated with nitrogen while oxygen passes through. The second filter begins to do the same while the first one is regenerated as nitrogen is expulsed (desorbed) by releasing the pressure. The process begins again, storing the oxygen and argon in a tank. The argon could be separated afterwards increasing the amount of oxygen up to 99%. Using a carbon mollecular sieve (CMS) based adsorbent, which absorbs the oxygen, allowing the impurities to be scrubbed. The maximum purity achievable in such systems is 99.3%. Typically the system is operated at a design point of 99.1% to optimize the output. In such a system there is about a 35% loss in the 94% feed product gas. This loss of product is sensitive to the purity level that is lower purity, less product loss. The whole process is intelligently controlled with help of automated valves and Siemens Make Pre-Programmed PLC.
