For various Heat Treatment process Cracked Ammonia widely used in steel industries. Mixture of Hydrogen & Inert Nitrogen are very much eligible for heat treatment process results.
DESCRIPTION
Ammonia comes through cylinder in ammonia cracker. In cracker, ammonia gas passes through bed of Special Nickel catalyst in an electrically heated furnace. Then ammonia cracked into 75% hydrogen & 25% nitrogen at 800 degree C temperature.
2 NH3 → N2 + 3 H2
The heat exchanger (shell & Tube Type) is used for better energy efficiency. While the hot cracked gas is cooled down, the ammonia gas is preheated using the counter current principle.
In order to reduce the dew point of the generated forming gas further, a special forming gas purifier is available. Using molecular sieve technology, the dew point of the generated gas can be reduced to -70°C.
Two Adsorber units are working in parallel. One is adsorbing moisture and un-cracked ammonia from the forming gas while the other one is heated for regeneration. Gas flow is switched regularly and automatically.
APPLICATION
- Heat Treatment Furnace for bright annealing
- Brazing Industry
- For Gas Purification System
- Stainless Steel Industry
- Power Sector
