Ammonia cracking produces 75% H₂ + 25% N₂ on demand on-site. Used as a protective atmosphere, reducing agent, and process gas across multiple industries.
Ammonia cracker produces H₂+N₂ from liquid ammonia stored on-site. No hydrogen tube trailers, cylinder deliveries, or scheduled refills needed.
Dissociated gas: 75% H₂ + 25% N₂ with residual NH₃ <10 ppm. Optional catalytic purifier achieves <1 ppm for demanding applications.
Liquid ammonia carries more hydrogen per liter than compressed H₂. 55% cost reduction vs. delivered bottled H₂/N₂ mixtures.
Single skid-mounted unit replaces multiple gas cylinder banks. Minimal floor space requirement for the production capacity.
