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:
NH₄NO₃ ------------ N₂O + 2H₂O

The reaction is ticklish and has to be controlled properly. If temperature of ammonium nitrate is allowed to go beyond a certain point then we do not yet yield. In our plant we almost get yield 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 undecomposed 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 scrubbery. Nitrous oxide as an oxide gas for atomic absorption in spectrophotometer and as fuel oxidant for racing vehicles.

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 analysed in the laboratory to ensure quality of the product and proper record is maintained.

We use water-lubricate compressor, which is also water-cooled and is better and more lasting when compared to air or oil cooled units supplied by others. The use of Gas Balloon in place of gas holders gives multiple advantages like: A. It does not occupy floor space. B Gas remains dry since it does not come in contact with water, which is present in case of gas holders. C. A gas balloon can hold a larger volume, which gives more flexibility in subsequent operations. Automatic control keeps the decomposition operation smooth and lets out the gas to the outer atmosphere in case of need. Minimum water and power consumption. Simplicity of operation is added benefits of the design created by our team. Double drying system.
