An ammonia cracker, NH3-Cracker or hydrogen generator is used for the production of forming gas. Hydrogen and Nitrogen are generated in a cost effective way in a volume ratio of 3 : 1 or in a weight ratio of 14 : 3. The absorber cleans the forming gas from remaining ammonia and moisture. The nitrogen in the forming gas can optionally be removed using a PSA basesd purification unit.

The NH3 is coming from bottles or from an ammonia tank. The ammonia gas is pre-heated in a heat exchanger and vaporizer and then cracked in the main furnace unit. The furnace is electrically heated.

The dissociation of ammonia gas NH3 takes place at a temperature of 800°C in the presence of a special nickel catalyst in an electrically heated furnace.

The heat exchanger is used for better energy efficiency. While the hot cracked gas is cooled down, the ammonia gas is preheated using the countercurrent principle. As a result of complete dissociation into hydrogen and nitrogen, very little undissociated ammonia remains and the dew point temperature of the resulting gas is very low (well below -10°C).
