Easy Operation And Installed, Cracked Ammonia Purification Unit, Hydrogen Purification Unit
Product Description:
The equipment consists of two molecule tower, valves, flowrate and operation cabinet. The cracked ammonia gas is a kind of mixed gas, which composed by 75% H2 and 25% N2, but this mixed gas contain some water and residual ammonia, which is harmful as the protective gas.so the purification process is a MUST. The purification unit adopt the molecule sieve adorption technology to absorb the water and residual ammonia. Normally the adsorption tank is designed in pairs , while one tank is for adsorbing and another is for renewing, so we can use them alternately.
Normally, this part is combined with the cracking furnace, but we can sell the purifiaciton unit indenpently too.
Above is the standard configuration.The ammonia cracker is a kind
of non-standard equipment, but we can design the equipment based on
customers' requirement. Some additional functions also can be
added:
1. PLC programmed controller can be added, which can automatically
control the various working states of the equipment.
2. Dew point detector can be added.
3. Gas content testing system can be added.

System Characteristics:
The gas made in this method is a good protective gas which can be
used widely in steel wire industry, metallurgical industry and other industries and science
research where need protective gas.
1. Ammonia is easy to be cracked: With not very high pressure,
under the reaciton of nickle catalysts, and a temperature controlled at around 800ºC, the ammonia will nearly
completely crack, with the cracking 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. So the water can be removed by adsorbing with a dew point of -60 ºC while the
gas going through the 5A molecular sieve. By this way, the water and residual ammonia which are
harmful in the processing point can be removed.
3. The liquid ammonia as raw material is easily 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).
