Ammonia Crackers Dealers in Vadodara

Air-Tech’s Ammonia Cracking Unit generates combination of Nitrogen and Hydrogen which is used in Heat Treatment Furnaces. Cracking of Ammonia is most economical way for On-site generation of Hydrogen Gas. For this process, the temperature of 850 Deg. C is maintained in the electrically heated furnace. A centrifugally cast retort is installed in the center of this furnace, which is filled with Nickle Catalyst. At this stage the Ammonia cracking takes place in presence of Nickel Catalyst and separates its vital element i.e. 75 % Hydrogen and 25% Nitrogen Gas at Dew Point of (-)30 Deg. C. As Nitrogen Gas is generally inert gas this mixture is treated as pure Hydrogen Gas. This becomes the most economical, tried , trusted and dependable source of on-site Hydrogen generation.For producing super dry gas, Molecular Sieves Filter is given after Ammonia Cracking Unit which reduces ammonia down to 1-ppm level and dries gas upto (-) 70 Deg. C. to (-) 80 Deg. C.   Application :  Heat Treatment  Galvanizing  Annealing 

NH3-Cracker or hydrogen generator is used for the production of forming gas. Hydrogen and Nitrogen are generated in a cost effective way. In a volume ratio of 3 : 1 or in a weight ratio of 14 : 3. Capacities from 1m3/h to 60m3/h are available. Ammonia cracking is a simple and cost effective method of manufacturing hydrogen, however it may be used only in the applications, in which presence of nitrogen is acceptable. The NH3 is coming from bottles or from or bulk tanker. The ammonia gas is pre-heated in a heat exchanger and vaporizer and then cracked in the main furnace unit. The furnace is electrically heated by special LGO heating elements. The decomposition of ammonia gas NH3 takes place at a temperature of 920°C in the presence of a special grade nickel catalyst in an electrically heated furnace. 2 NH3 gives N2 + 3 H2 The cracked gas then passes to the heat exchanger for cooling and for pre-heating the incoming gas. This way and in combination with the low power consuming LGO heating elements, it can be made sure that only a minimum of electricity has to be used for the cracking process. * Ammonia cracking is a process of dissociation (decomposition) of gaseous anhydrous Ammonia (NH3) into a mixture of Hydrogen (H2) and Nitrogen (N2) according to the reaction: 2NH3 = N2 + 3H2 * The reaction is endothemic, requiring 383 kJ/mol. The process is performed at increased temperature within the range 1560-1740ºF (850-950ºC) in the presence of special grade nickel as catalyst. The resulting gas mixture is composed of hydrogen and nitrogen in the proportion 3:1 (75% of H2 and 25% of N2) with very little amount (20 -100 ppm) of residual undissociated ammonia with dew point -60ºF to -20ºF (-51ºC to -29ºC). The gas may be further purified by molecular sieves purifier resulting in reducing the uncracked ammonia to 1-3 ppm with dew point -110ºF (-80ºC). Available Capacities. 0 m3/hour to 60 m3/hour. Salient Features * Easy to operate.* Low capital cost* maintenance free operation.* Low running cost* Available in diffrent capacities.* Long service life.* Very cost effective alternate for water Electrolysis Plants in terms of power, capital cost and running cost Applications * Annualy furnance in cold rolling industries.* For providing atmosphere in Hydrogen Bell.* For providing reduction in bulk drug.* Stainless steel wire annealing.* Continuous galvanizing lines.* Bi-metal products annealing.* Sintered products annealing.* Metal Powder annealing.* Brazing application.* Heat treatment.  

Cracked Ammonia finds wide application in steel industry for various heat treatment processes. We design, manufacture and supply customized ammonia cracker to meet customer’s demand as per their requirements. Heat treatment results are found very sound in the presence of mixture of hydrogen and inert nitrogen. Basic Description Ammonia gas from cylinders passed over a bed of nickel catalyst at 850°C temperature and cracking take place in two different gas i.e. 75% Hydrogen and 25% Nitrogen. 2NH3->N2 + 3H2 (In Presence of Nickel Catalyst at 850°C) Ammonia cracking is endothermic reaction and require heat from other source. The source is electrically heated/gas fired furnace (Rectangular Shape) and a retort made of heat resistance alloy is provided to hold the ammonia cracking catalyst. Cracked ammonia from furnace is cooled to ambient temperature in a shell &Tube type heat exchanger and having dew point around (-) 30°C. Further product gas is passed through a molecular sieves filled Gas Purifier to achieve a dew point up to (-) 80°C.
