Nitrous Oxide Plant
Safe and economical. The Nitrous Oxide plant is a plant with an efficient Generation system which reduces power consumption and adds on to safety.
Nitrous Oxide is produced by thermal decomposition. Heating of Ammonium Nitrate to 250 degrees releases Nitrous Oxide & steam.
The steam is then purified by various processes. After which the gas is stored in cylinders with the help of a compressor.
Components of nitrous oxide plant
Melter and Reactor
Decomposition of ammonium nitrate in water can start at 210°C . It would take a long time to reach the thermal set point around 255°C . So to accelerate the starting process the ammonium nitrate solution is heated in the reactor to approximately 240°C.
Nitrous oxide Condenser
Leaving the reactor, water is saturated and passes through a condenser for its removal.
The condensed water contains ammonium nitrate and nitric acid and should be reused. It should be purified before discharge.
The gas leaving the condenser contains impurities. Which are produced by decomposition of the ammonium nitrate. The purification is carried out in absorption towers by washing the gas in a closed circuit
Gas from Purification Towers has condensate moisture that can be extracted in Moisture Separator
Product is fed to the compressor directly to A Three stage non lubricated reciprocating compressor. This increases the Nitrous Oxide pressure up-to working pressure . Cooling coils and condensate traps are located at each stage. The entire assembly of the compressor, with its coils and traps, is submerged in water for maximum cooling of the Nitrous Oxide gas.
The drying unit removes by adsorption the water vapour from the compressed gas.
High Pressure Storage
Nitrous oxide is Stored in six number of pressure vessels or pressure tanks at a pressure of 15 Bars for buffer for liquefaction unit.
The nitrous oxide is liquefied by a refrigerant at temperatures down to –20°C
Cylinder Filling Ramp
Charging of the cylinders can be accomplished as per user requirement. Cylinder filling ramps are split in 2 Pcs each ramp of 5 to 50 point installed with safety instruments and tail pipe for filling to cylinders and are mounted over MS Ramp.
Nitrous Oxide Plant arrives on skids pre-piped. Even in the most inclement or freezing Weather, installation is simpler because of minimum on-site assembly.
Safety of plant
Safe operation is the most important feature of Our plants. flame arresters and reverse flow check valves provide unequalled protection in the cylinder filling process.
With the same high Nitrous Oxide yield as other our plants are more compact, and less costly than larger capacity plants.
Our plant requires less space than any competitive model of the same capacity.
reduces the need for additional cylinders as fast refill increases the effective use of cylinders
