N₂O Abatement with Catalytic Nitrous Oxide Technology
Shell Catalysts & Technologies offers an innovative, energy-efficient tertiary solution for N2O reduction based on our unique lateral flow reactor (LFR) technology to combat environmental threats and enable industrial plants to both meet clean air regulations and participate in carbon credit programmes.

N₂O reduction in tail streams
With an environmental impact 310 times higher per unit than CO2, nitrous oxide (N2O) has been identified as a significant greenhouse gas (GHG) under the Kyoto Protocol. Shell Catalysts & Technologies’ solution destroys N2O, converting it into naturally occurring nitrogen (N2) and oxygen (O2). It is well suited to reducing N2O emissions from the tail gas streams of industrial and chemical process plants such as nitric acid, caprolactam and adipic acid plants – all significant emitters of N2O.
Key benefits of Catalytic Nitrous Abatement Technology (CNAT)
No reducing agents or reactants
CNAT is a direct N2O decomposition process that does not require the addition of reducing agents or other reactants. N2O destruction of 98% or higher can be achieved over a range of temperatures and pressures, and no undesirable by-products are formed.
Robust yet cost-effective
C-NAT is dependable and more cost-effective than alternative technologies on the market.
Eligible for carbon credits
In regions where carbon markets are in effect, N2O-reduction projects can be used to generate tradable carbon credits and financial revenues.
Applications for CNAT
Nitric acid plants
Relative to an expander, CNAT can be installed upstream, where pressures are higher, or downstream, where pressures are lower. Both options can benefit from low pressure drop by using the LFR technology.
Caprolactam plants
Certain processes for the manufacture of caprolactam can have high N2O emissions. CNAT is stable in the presence of small quantities of SOx, which are sometimes present in caprolactam process tail-gas.
Adipic acid plants
Excellent performance benefits can be gained by employing a highly active catalyst on tail gas emissions, thereby offering significant N2O reductions while maintaining low pressure drop.

Our catalytic nitrous oxide reduction solutions can help you meet environmental regulations
Robust yet cost-effective, the Shell Catalysts & Technologies’ N2O abatement technology is a dependable system and far more cost-effective than other technologies available on the market for high N2O reduction.
Exceptional performance benefits can be gained by employing a highly active catalyst on tail gas emissions, offering significant N2O reductions while having only a low impact on plant operations.
