Process Description
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
scrubber. 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 analyzed in the laboratory to ensure
quality of the product and proper record is maintained.
