High Efficiency Ammonia Cracker For Heat Treatment Gas Atmosphere
The device is for producing 75%H2 + 25%N2 mixed gas. Ammonia decomposing generator is including hydrogen plant and purification plant( short title ammonia decomposition ) is the unit that designed and produced which according to the Ammonia cracking chemical reaction. Due to the convenient source and lower cost of ammonia decomposition, the application range are more and more wider, it mainly used for: Bright annealing of metallic materials, such as the bright annealing treat of stainless steel strip, silicon steel sheet, precision alloy, brass strip., etc; Reduction and sintering of powder metallurgy Mix deoxidize with industrial nitrogen, as hydrogen rate controlled nitrogen-based atmosphere, and replace the expensive hydrolysis of hydrogen. The equipped nitrogen-based atmosphere, can use for float glass production line, copper tubing, bright annealing of strip, and carrier gas of low-carbon alloy steel., etc. And also used as Virgin gas of making high pure hydrogen (equipped nitrogen and hydrogen separation devices can obtain high pure hydrogen).
Bright annealing is an annealing process performed in a vacuum or a controlled atmosphere containing inert gases (such as Ammonia decomposing gas, hydrogen). This controlled atmosphere reduces the surface oxidation to a minimum which results in a brighter surface and a much thinner oxide layer. Pickling is not needed after bright annealing since the oxidation is minimal. Since there is no pickling, the surface is much smoother which results in better resistance to pitting corrosion.

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 catalysts, and 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).
1. PLC programmed controller can be added, which can automatically control the conversion of various working states of the equipment.
2. Dew point detector can be added.
3. Gas content testing system can be added.
