Hydrogenation Purification to Nitrogen
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.
Hydrogenation purification composed of mixer, catalytic reactor, after-cooler, cyclone separator, filter or adsorption dryer, oxygen analyzer, flow meter and product nitrogen buffer tank.
Suitable for industries that are not sensitive to hydrogen, such like heat treatment, powder metallurgy, copper smelting and processing, iron and steel processing, bearing, chemical industry, electronics, glass, metal and magnetic materials.
☆ Simple operation, convenient maintenance and stable performance;
☆ Integrated skid structure design, easy installation and small land occupation;
☆ Use the high-efficiency catalyst to deaeration without activation;
☆ Interlocking control with air purification and PSA nitrogen generation;
☆ Wide range of requirements for common nitrogen in 98 ~ 99.9%;
☆ The mixing is completed in the static mixer with good effect and less hydrogen consumption;
☆ Automatic nitrogen hydrogen proportioning that is fully automatic control with small lag, high adjustment accuracy, safety and reliability;
