Our ammonia cracker produces mixture of hydrogen and nitrogen, which is mostly used for heat treatment furnace. Ammonia cracking takes place in presence of nickel catalyst at 8500 c temperature and cracks ammonia to n2 + h2 mixture containing 75% hydrogen and remaining 25% nitrogen. The cracked ammonia gas contains around 80 ppm un-cracked ammonia impurities and its dew point is only (-) 300 c.
