Large Scale Industrial Ammonia Cracking Plant Nh3 Hydrogen Shielding Gas Anticorrosion

Float glass field hydrogen produced by ammonia cracker as shielding gas anticorrosion with CE certificates

BASIC DESCRIPTION

Ammonia gas from cylinders passed over a bed of nickel catalyst at 850℃ temperature and cracking take place in two different gas i.e. 75% Hydrogen and 25% Nitrogen.

2NH₃->N₂ + 3H₂ (IN PRESENCE OF NICKEL CATALYST AT 850℃)

Ammonia cracking is endothermic reaction and require heat from other source. The source is electrically heated/gas fired furnace (Rectangular Shape) and a retort made of heat resistance alloy is provided to hold the ammonia cracking catalyst.

Cracked ammonia from furnace is cooled to ambient temperature in a shell &Tube type heat exchanger and having dew point around (-) 30℃. Further product gas is passed through a molecular sieves filled Gas Purifier to achieve a dew point up to (-) 80℃
