About Ammonia Dissociator
Ammonia Dissociator manufactured by United Enterprises is a specialty atmosphere generator that thermally dissociates anhydrous ammonia into 75% hydrogen and 25% nitrogen a clean, reducing atmosphere for industrial heat treatment.
Brief Description:
Ammonia dissociators are widely used in bright annealing, sintering, brazing and jewellery applications. They offer a cost-effective alternative to bottled hydrogen, with the convenience of liquid ammonia storage and on-demand gas generation.
Our Ammonia Dissociators use a nickel catalyst at 900C1000C to crack NH into H and N. Capacities from 5 Nm/hr to 100+ Nm/hr are supplied, with PLC / SCADA control, water cooling and PSA / molecular-sieve drying for low residual NH.
Each unit is engineered around the customers furnace size and atmosphere quality target.

FAQ's of Ammonia Dissociator:
Q: How does the Ammonia Dissociator work and what is its main principle of operation?
A: The Ammonia Dissociator operates by passing high-purity ammonia (99.99%) over a nickel-based catalyst at temperatures between 800C and 900C. This process, known as cracking, breaks down ammonia into a gas mixture of 75% hydrogen and 25% nitrogen, widely used for creating protective furnace atmospheres.
Q: What are the typical applications of the Ammonia Dissociator?
A: This equipment is commonly used in the metallurgical industry for heat treatments, brazing, sintering, annealing, bright annealing, and as a furnace atmosphere generator. Dissociated ammonia provides an ideal reducing environment for these critical industrial processes.
Q: Which safety features are included in the Ammonia Dissociator?
A: The unit is equipped with a pressure relief valve, flame arrestor, and alarm system to ensure safe operation. These components provide multiple layers of protection against overpressure, flame propagation, and operational anomalies.
Q: When is it beneficial to use a skid-mounted Ammonia Dissociator?
A: A skid-mounted design allows for fast installation, easy relocation, and integration into existing industrial setups. This format is particularly beneficial when flexibility and minimization of downtime are critical during facility upgrades or expansions.
Q: Where can the Ammonia Dissociator be installed and what are its mounting requirements?
A: The dissociator can be installed in industrial facilities requiring controlled atmosphere gases, such as steel plants or heat treatment workshops. Its compact skid-mounted structure simplifies placement, needing only standard connections for ammonia feed, power supply, and exhaust.
Q: What advantages does the integrated heat exchanger offer in this system?
A: The integrated heat exchanger or gas cooler improves energy efficiency by recovering heat from the process gases. This not only cools the output gas to desired temperatures but also reduces overall operating costs by utilizing waste heat effectively.
