Pressure Electrolysis based / Methanol Reforming Based / Ammonia Cracking Based
Ammonia Crackers produces Cracked Ammonia( NH3) Gas using Anhydrous ammonia from cylinders. Cracked ammonia contains 75% Hydrogen and 25% Nitrogen and the product gas is very dry & oxygen free.
In heat treatment furnaces, this gas has wide use as reducing atmosphere. Wherever pure hydrogen is needed , Cracked Ammonia Gas serves as a very cost-effective. Substitute.
The dissociation of Ammonia Gas takes place in the presence of a NICKEL CATALYST at temperature of 850 Deg C. to 900 Deg. C. in an electrically heated or fuel fired automatic Furnace. Nickel Catalyst promotes the following chemical reaction:
2NH3 = N2 + 3H2
The cracked gas production amounts to 2.63 NM3 per Kg of ammonia feed stock, with residual ammmonia contents less than 20 ppm and dew points upto ( - ) 50 Deg. C.
Main application of cracked ammonia gas is in heat treatments, i.e. Sintering, Brazing, Bright Annealing etc. as protective gas
Certain applications specify the need of gas having extremely low residual ammonia contents and very low gas dew point. Such high quality of clean and dry protective gas can be achieved by employing MOLECULAR SIEVE PURIFIER after the ammonia cracker. After the purifier, the residual ammonia contents fall below 3 ppm and dew point of gas improves upto (-) 80 Deg. C.
| Capacity offered : | From 1 Nm3/hr to 500 Nm3/hr |
| Moisture content (Dew-Point) : | - Minus 50 Deg. C Normal - upto minus 80 Deg. C can be achieved with additional purifier |
| A) Raw ammonia content : | 20-25 ppm normal less then 3 ppm with additional purifier |
