DESCRIPTION OF PROCESS
Nitrous Oxide ( N2O ) is manufactured by thermal decomposition of Ammonium Nitrate.
NH4NO3---------------------------> N2O 2H2O
( Nitrous Oxide ) ( Water )
Ammonium Nitrate is melted and decomposed by reaching to a temperature of approximate 2500C to 2600C to give a mixture of Nitrous Oxide and super heated steam as per above reaction. At the same time impurities are produced including Ammonium Nitrate fumes, Nitrogen and Oxide of Nitrogen. The Steam and impurities are removed by scrubbing in turn with water, caustic soda and finally acid scrubber.
From the decomposition pot the hot gas including impurities enters the primary scrubber. The scrubber is fitted with a small condensing coil mounted at its top to condense water from part to the effluent gas stream and this water provides a counter-current flow for recovery of ammonium nitrate fumes from the gas. N2O gas leaving the primary scrubber passes to a stain steel water scrubber for the removal of ammonium nitrate fumes.
Finally, the gas passes through a mild steel caustic soda scrubber followed by a fiber glass / stain steel acid scrubber. The circulation of caustic and water to the respective scrubber is maintained by me of pumps. The scrubber gas is then allowed to collect in a rubber gasholder ( balloon ). The gas from the gasholder is sucked by a multi stage water lubricated compressor, which compresses the gas to approx. pressure of 65 kgs/cm2depending on ambient temperature.
The compressed gas passes through a gravity type water separator before being dried in Alumina Drier Battery. Finally Nitrous Oxide in liquid form is collected in a bank of three storage vessels. The storage vessels are kept cool by spraying chilled water on them.
During storage the impure nitrogen gas is being removed by venting out the gas after cooling down the storage vessels. The pure liquid nitrous oxide is then filled into cinders by weight. For this, the cinders are to be filled by keeping them on a weighing scale. Nitrous Oxide is liquefiable gas and is stored in cinders in liquid form only.
