How we produce our own nitrogen and oxygen?
In nature, nitrogen has a wide distribution, and it is the main component of air. In dry air, nitrogen and oxygen content accounted for 78% and 21%. So, as the biggest raw material storage, air is never can be used up.
Low pressure N2 can be produced by separating oxygen and nitrogen in air by using the pressure swing adsorption (PSA) process. Dry & oil-free compressed air produced in our Compressed Air System enters the PSA Nitrogen Generator and is first stored in the Dry Air Receiver from where it enters the PSA System. Here the oxygen is adsorbed by the Carbon Molecular Sieves and nitrogen comes out as a product gas. The N2 enters the Surge Vessel where its purity is stabilized before it is sent to the Nitrogen Vessel and then drawn for use. Necessary measurement and control devices are incorporated to make the N2 Generator fully automatic as well as to ensure that only pure N2 goes to your User equipment.
The Origin of the Name of Nitrogen and Oxygen
The French chemist A.L.Lavoisier(1743-1794) used scale as the tool to research the chemistry at an early time and paid attention to the changes of the quality of objects in the chemical reaction. As soon as he knew Priestley refined oxygen from mercury oxide, he underwent a famous experiment to research the components of the air (referencing the first chapter of the reading material). He got rid of the the traditional false theory(phlogiston) and made scientific judgements based on the facts, demonstrating that the burning was the object reacting to the oxygen in the air. The specific item “phlogiston” did not exist at all. In 1777, based on other chemists’ understandings, Lavoisier realized that air is the combination of two gases, one helps burning and breathing, which he called “Oxygen”, meaning the elements to form acid. The other does not help burning and breathing was named as “Nitrogen”, meaning it cannot maintain the life.
