Industrial ammonia dissociation unit for H2+N2 atmosphere gas
Electric catalytic ammonia cracker that produces mixed hydrogen-nitrogen atmosphere gas (nominal 3H2+N2) for heat treatment, sintering, and related industrial uses.
Problem solved
Users need a stable reducing/protective atmosphere without bulk hydrogen logistics; cracking liquid or vapor NH3 onsite yields a controllable H2-rich mixed gas with low residual ammonia and low dew point after drying.
Application contexts
- Bright annealing of stainless and high-chromium steels
- Powder metallurgy sintering atmospheres
- Brazing and general heat-treatment protective gas
- Pilot feed for H2-from-NH3 process development (with further purification)
Technical principle
Vaporized NH3 is passed through a heated catalyst-filled retort (2NH3 → 3H2 + N2); product gas is dried to remove residual moisture and unreacted NH3. Official AX line spans roughly 3–100 Nm3/h product gas with stated residual NH3 ≤10 ppm and dew point ≤−60°C at delivery condition.
Typical use cases
- Factory atmosphere gas generator replacing cylinder H2 logistics
- Small-scale NH3 cracker for process R&D and heat-treat lines
Partnership route
How global engineering teams typically engage this asset.
Helpful to include: required product gas flow (Nm3/h) · residual NH3 and dew-point limits · power and cooling utilities available · need for dryer package · spare heater/retort lead time
