Cracking of ammonia is one of the most economical ways for on-site generation of hydrogen gas for industrial purposes. For this process, the temperature of 850°C is maintained in the electrically heated furnace. A centrifugal cast retort is installed in the center of this furnace. This furnace is filled with a nickel catalyst. At this stage, the ammonia cracking takes place in presence of nickel catalyst. The process separates its vital element into 75% hydrogen and 25% nitrogen gas at a dew point of (-)30°C.

In fact, nitrogen gas is generally inert. This mixture is treated as pure hydrogen gas. This becomes the most economical, trusted, tried and dependable source of on-site hydrogen generation for many small and large industries. A molecular sieve purifier is used after ammonia cracking unit for reducing residual ammonia content and to get very dry gas. This reduces ammonia down to 1-ppm level and dries gas up to (-) 80°C dew point.

Industrial Uses:

• Purified Hydrogen and Nitrogen gas mixture from these Ammonia Cracking plants are used in:
• In Heat treatment furnaces while the process of Annealing, Sintering, and Galvanizing
• Reducing furnace atmosphere
• Stainless Steel bright annealing
• Carbon Steel bright annealing
