Another big practical benefit is that you can install the Topsoe monolith solution in your existing reactor, or switch to a smaller, simpler reactor design.
A unique advantage to the Topsoe monolith is its low pressure drop, which enables you to use a polisher setup combined with secondary N2O abatement.
Secondary N2O abatement normally has a maximum efficiency of 80%, leaving behind significant N2O emissions – with an associated CO2 price. This is why the Topsoe TertiNOx™ solution can be used as an N2O polisher to reduce N2O emissions even further, which also reduces your costs for CO2 equivalents. An advantage to all nitric acid plants operating with secondary N2O abatement.
