Separation from adipic acid off gas
About separation from adipic acid off the gas. It’s used because hexanedioic acid process units by-product nitrous oxide; general adipic acid per ton can produce about 0.28 tons of nitrous oxide. Nitrous oxide content is nearly 50% (wt) and recycles value well in tail gas.
The method for preparing high-purity nitrous oxide using adipic acid production tail gas using the following steps:
(1) Absorption pretreatment process: Adipic acid produces tail gas and enters the absorption tower; the absorbing liquid at the bottom of the tower will absorb most of the CO2、NO2, and H2O.
(2) cryogenic rectification process: the airflow from adsorbent equipment enters a low-temperature fractionating tower. High-purity nitrous oxide is obtained from the low-temperature purifying method column.

Thermal decomposition of ammonium nitrate (NH4NO3)
Nitrous oxide is produced by careful heating of ammonium nitrate at about 250℃, which decomposes into nitrous oxide and water vapour:
NH4NO3 → 2 H2O + N2O
Ammonium Nitrate is decomposed in the Melters to give a mixture of Nitrous Oxide & superheated steam. At the same time, impurities are produced, including Ammonium Nitrate fumes, Nitrogen & other oxides of Nitrogen. The steam & impurities are removed by scrubbing with water, caustic soda and sulphuric acid. Nitrogen present in traces is removed by bleeding from the top of storage vessels where Nitrous Oxide is stored after compression by a compressor.
WHO, FDA and GB standards approve nitrous oxide from this method for food additives.

For food-grade nitrous oxide for sale, including whipped cream chargers, please confirm that the thermal decomposition of ammonium nitrate produces nitrous oxide.
Nitrous oxide produced from this method is usually used in the electronic industry. It’s not approved for food grade. Food using nitrous oxide is only produced by the last method.

Nitrous Oxide Production

The production of nitrous oxide is based on the continuous thermal decomposition of ammonium nitrate at a concentration of 90±2% and at a temperature of approximately 250 °C. The chemical formula of the decomposition is: NH4NO3 → N2O + 2H2O + HEAT. The reaction is exothermic.
Chemical formula of decomposition:
