Principle
Device with liquid ammonia as raw material, through after vaporization will ammonia heated to a definite temperature in catalyst, ammonia nitrogen and hydrogen to decompose, ammonia gas mixture of chemical formulas are as follows: 2NH3 = = 3H2 + N2-22080 card, namely under normal conditions, 1kg complete decomposition can produce ammonia nitrogen gas mixture 2.64 Nm3 hydrogen, according to the chemical formula, gas, and 25% by 75% H2 N2. By imported ammonia gas pressure, the pressure differential pressure < 0.05 decision MPa. After the decomposition of mixed gas cools by heat into dryer for residual ammonia and trace the depth of water adsorption, thus made dry nitrogen purity hydrogen mixture.
Durable, High Efficiency and Energy Saving
1. Precision temperature control: Imported intelligent temperature control instrument has low temperature control accuracy and failure rate.
2. Special Catalyst: Special Catalyst produced by Southwest Chemical Park is not easy to pulverize.
3. Heating components: high-quality Cr20Ni80 electric heating bias band.
4. Strong energy-saving: Thicker insulation layer, slow heat dissipation, non-hot outside wall of heating furnace, high energy-saving efficiency.
5. Long service life: Cr25Ni20 heat-resistant stainless steel pipe without oxide skin at 900 C is used as decomposition furnace gallbladder material, and Inconel 600 pipe or Cr25Ni20 heat-resistant stainless steel pipe with high temperature corrosion resistance is used as ammonia feeding pipe, which has long service life.
