Palladium catalyst high purity hydrogenation purifier to get 99.9995% purity N2 used for metallurgy field brightness
Technical indicators:
The raw nitrogen will be produced by PSA or membrane separation, and mixed with small amount of hydrogen. Residual oxygen reacts with hydrogen to produce water vapor in a reactor filled with metal palladium catalyst, therefor, most of the water vapor is condensed through the after-cooler, and the condensed water is removed through the high-efficiency water separator. After deep dehydration and dust removal in the dryer, the high purity nitrogen is obtained finally.
By the way, The adsorption dryer can make the dew point of product gas below - 70℃. The purity of product gas continuously monitored online by analyzer.
The chemical equation is: 2H2 + O2 = 2H2O + Heat
In order to ensure that oxygen is completely removed, the actual ratio of H2 to O2 is slightly higher than the theoretical value, so that the reaction is very complete to obtain the high purity nitrogen, and the purity can reach more than 99.9995% after refining.
Main Characters:
1. Advanced technique------The highly active deovo catalyst which is rather advanced in the country is adopted. The activity is excellent and can be regenerated without heating.
2. Automatic control------This equipment adopt the Siemens PLC control system with automatic switch to control work regeneration, with optional quality flow controller, and with automatic hydrogenation under controlled ratio.
3. Reliable running status-----This equipment adopts German pneumatic valves and Japanese RKC temperature controller.
4. Reasonable design------The totally enclosed design ensures a compact structure, a good looking appearance and a small floor space.
