Hydrogen Generation Ammonia Cracking For Industria Gavalnizing
Ammonia Cracking Working Principle:
Nitrogen/Hydrogen generator by Ammonia Cracker for generation of forming gas takes
liquid ammonia as the source. Having being vaporized, the ammonia
then is heated and decomposes into the forming gas with 25%
nitrogen and 75% hydrogen under the action of catalyst. In theory,
one Kg of ammonia can produce 2.64 Nm3 mixed gas.
Our equipment possesses the characteristics and advantages of
compact structure, low space requirement, small investment, simple
operation, low energy consumption and long service life.
Supported by and combined with the XRFC series purifying equipment
of our company, the higher purity shielding gas can be obtained.
However, the ammonia as source must be of first class or above, to
be exact, the purity of the source ammonia must be no less than 99.8%.
Ammonia Cracking Properties and Characteristics:
The gas made in this method is a good protective gas which can be
used widely in semiconductor
industry, metallurgical industry and other industries and science
research which need protective gas.
1. Ammonia is easy to decompose: With not very high pressure, under
a temperature controlled at 750~800ºC, the ammonia will nearly
completely decompose, with the
decomposing rate reaching 99.9%.
2. Easy to refine the gas: As the raw material, the liquid ammonia
is of very high purity. The volatile
impurities are only little inert gas and water dissolved in the
liquid ammonia and there is nearly no
oxygen. Meanwhile, under such conditions, the ammonia decomposition
is irreversible. So the water
can be removed by adsorbing with a dew point of -60 ºC while the
gas doing through the 5A molecular
sieve. By this way, the nonmetallic elements, for example, chlorine
and oxygen which are unpopular
in semiconductor industry can be removed.
3. In China, the liquid ammonia as raw material is accessible at a
low price and the raw material
consumption is also relatively smaller( In theory, each Kg of
ammonia can create 2.64 Nm3 mixed gas).
