Unități de Purificare a Azotului Deoxy
Deoxy Nitrogen purification units are devices used to separate nitrogen in the air from oxygen, carbon dioxide and other gases. The purification process is done by taking advantage of the differences between the molecular sizes and physical properties of the gases in the air.
In the catalyst unit, palladium-coated alumina binds externally introduced hydrogen gas atoms. The remaining (1,000 ppm) oxygen gas molecules in the 99.9 purity nitrogen gas produced in the PSA generator combine with hydrogen gas on palladium alumina and turn into water, thus raising the nitrogen gas to an ultra-pure level.
The water in ultra-pure nitrogen gas is dried with the help of a special desiccant dryer, and ultra-high purity 99.9999 (1ppm O2) nitrogen gas, purified from oxygen and moisture, is transferred to the systems.
A special automation system is used to ensure the most efficient and minimal consumption of hydrogen gas used in the catalys.
