Atividade

The air we breathe contains two gases that are extremely useful in industry: oxygen (about 21%) and nitrogen (about 78%). Adding oxygen to a process enables better control of heating patterns, higher furnace efficiencies (for lower fuel consumption) and reduction in particulate and NOx emissions. It’s used with fuel gases to enhance processes including gas welding, gas cutting, oxygen scarfing, flame cleaning, flame hardening and flame straightening. Oxygen is a raw material in many oxidation processes and to regenerates catalysts. Nitrogen gas is used for purposes ranging from inerting and purging to flushing and sterilizing to product transfer and packaging. Many such processes remove undesirable oxygen from a manufacturing process or environment, preventing oxidation that can damage metal parts and sensitive electronics. Nitrogen is also used in refining and gas separation processes. Since oxygen and nitrogen occur together in the air, they must be separated before they can be used. The right tool for the job is an oxygen generator or a nitrogen generator.
