Production line of Nitrous Oxide- DSW Manufacturer
DSW is one of the leading manufacturers and exporters of nitrous oxide plants or n2o factories. DSW’s Nitrous Oxide plant is very safe and economical, with an efficient Generation system that reduces power consumption and adds to safety.
Separated elements mean that the plant units have fixed dimensions, but the layout of the complete plant is roughly free owing to the different length ad shapes of the connection tubes between the teams.
The installation and start-up process requires more time; some connections are only finished on the Customer’s site.

Nitrous Oxide Plant
The primary industrial process for producing nitrous oxide involves the thermal decomposition of ammonium nitrate. However, other methods are also available, such as direct oxidation of ammonia or purifying off-gas from polyamide chain production to create it.
Production line of Nitrous Oxide
Production Processing
In the Melters, Ammonium Nitrate decomposes to produce a mixture of Nitrous Oxide and superheated steam. Ammonium Nitrate fumes, Nitrogen, and other Nitrogen oxides are also produced. In order, moisture and impurities can be removed using sulphuric, acidic, and caustic soda. Nitrogen traces are removed after compression with a compressor by bleeding the tops of storage vessels that store Nitrous Oxide.
Ammonium nitrate is melted in a melter. The molten ammonium nitrate flows into a combustion pot, decomposing ammonium nitrate according to the following reaction.
The reaction is a touchy one and must be controlled. The formation of N2O is prevented if the temperature is allowed to exceed a certain level. We have achieved a reaction efficiency of 95% in our plant. However, in practice, N2O combustion can also produce other impurities. Ammonium nitrate fumes and undecomposed ammonium are present. The primary scrubber recovers these gases. In the first water scrubber, the steam from the hot gas condenses, and the moisture and ammonium nitrate entrained in it are separated in the mist separator. The caustic cleaner removes residual ammonium, carbon dioxide, and other nitrogen oxides.
Application
Nitrous oxide may be used as an aerosol propellant in various fields:
– for whipped cream (because it improves the foaming characteristics of the cream), syrups, concentrates of coffee, chocolate, various flavors, sauces for grilled meats, vinaigrette, etc.
– pharmaceutical field
– cosmetics (perfumes, eau de cologne, hair spray, etc.)
– household products, paints, varnishes, insecticides
– aerosols for low temperatures, such as de-icers, engine starting boosters, etc.
