The equipment is called ammonium nitrate N2O gas production equipment
Production Capacity: 25, 60, 80 kg per hour
We are a manufacturer of producing 99.9% N2O gas machine and 99.999% N2O gas euqipment (nitrous oxide) since 2012 year, since that we have also developed and designed of manufacturing N2O gas machines. The N2O gases are used for production of Integrated circuit device,IC card, LED, LCD,microelectronics and photovoltaic as well as other industries; It mostly used by electronics factory for making screen of mobile or other electronics products.
Ammonium nitrate (even technical grade) is melted in a melter. The molten ammonium nitrate flows into a combustion pot where ammonium nitrate is decomposed according to the following reaction.
The reaction is ticklish and has to be controlled properly. If temperature of ammonium nitrate is allowed to go beyond a certain point then N2o is not formed. In our plant we almost get Efficency of reaction equal to 95% or even more. In practice, however, with N2O some other impurities are also obtained as products of combustion. There is some un decomposed ammonium nitrate, with its fumes. These are recovery in the primary scrubber. The steam in the hot gas is condensed in the first water scrubber and the entrained moisture and traces of ammonium nitrate get separated in the mist separator. The residual traces of ammonium nitrate, carbon dioxide and other oxides of nitrogen are removed in the caustic scrubber.
The gas containing some nitrogen is then stored in the gas balloon. The gas is compressed with a compressor, dried in a drier and then refrigerate when it becomes liquid. Liquid nitrous oxide is stored in high-pressure storage vessel into cylinders and the gas is filled by weight. In a low pressure plant the gas after refrigeration is stored in a storage tank and from there it is filled in cylinders with a pump. Each batch is analyzed in the laboratory to ensure quality of the product and proper record is maintained.

For medical use, it is a Surgical anaesthetic, widely used at hospital or clinic . For food grade use, It is an excellent food preservative, non-toxic, harmless and pollution-free, the milk dissolved with N2O can keep fresh for a long time without refrigeration, so it is widely used at coffee shop. With the development of LED, LCD,microelectronics and photovoltaic industry line , the demand for N2O gas are increasing rapidly, and still keep on rising in the next decade, it is a good time if your company want to invest a N2O gas plant to produce N2O gas.
