Tertiary N2O abatement
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. To combat this environmental threat and enable industrial plants to both meet clean air regulations and participate in carbon credit programs, CRI offers an innovative, energy-efficient tertiary solution for N2O decomposition based on our unique lateral flow reactor (LFR) technology.
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.
