Liquid ammonia was heated to 800 ~ 850 ℃, in the nickel-based catalyst, the decomposition of ammonia, hydrogen and nitrogen can be a mixed gas containing 75% H2,25% N2 of:

      This means the process has brought a bottle of liquid ammonia through the ammonia into the ammonia valve F1, F2 to enter the carburetor (1), carburetor built with electric heating elements, electric heating elements for heating water in the carburetor, the general temperature control in 45-60 ℃, liquid ammonia to obtain warm water over the heat transfer in the evaporator. Vaporized into gaseous ammonia, ammonia vaporized pressure is generally controlled 0.4-0.5MPa, after ammonia gas after decompression valve, pressure at about 0.05 MPa. After the ammonia down by decay after dosing flow meter from flowing ammonia gas in a heat exchanger in heat exchange, so that the ammonia temperature by decomposing furnace out of the high-temperature gas mixture is cooled, warmed by decomposition of ammonia into the furnace is decomposed into hydrogen and nitrogen mixed gas, high-temperature mixture into the heat exchanger to cool the water cooler, and then sent to the point of use.

Duplex processes, with two parallel adsorption dryer, a job, while the other can be regenerated. Alternating work and regeneration to ensure continuous operation of equipment. Dryer work at room temperature, heated to 350 ℃ under gassing regeneration. After regeneration waste gas valve F17, through the gas-water separator vent.
