Tertiary N₂0 abatement

This CRI technology 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.

C-NAT has been tested under a wide range of conditions and is capable of achieving N₂O reductions of more than 98%. C-NAT is a direct N₂O decomposition process that does not require the addition of any reducing agent or other reactant. N₂O destruction of 98% or higher can be achieved over a range of temperatures and pressures, and no undesirable by-products are formed.

C-NAT can be installed in either the high-pressure position upstream of the expander or in the low-pressure position downstream of the expander. Both options benefit from low pressure drop by utilising the LFR.

Robust yet cost effective, the CRI N₂O Abatement Technology is a dependable system and far more cost effective than other technologies available on the market.

Certain processes for the manufacture of caprolactam can have high N₂O emissions. The CRI N₂O decomposition catalyst is stable in the presence of small quantities of sulphur oxide (SOx) sometimes present in caprolactam process tail gas. Environmental and financial benefits: N₂O reduction projects can be used to generate tradable carbon credits and financial revenues.

Exceptional performance benefits can be gained by employing a highly active catalyst on tail gas emissions, offering significant N₂O reductions while maintaining low pressure drop.

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.
