Ammonia Oxidation Solutions

By providing highly selective and efficient ammonia oxidation solutions, we support a broad variety of final applications that require nitric oxide as precursor: nitrates for fertilizers to feed the world, nitrates for explosives to gain steel for building, hydroxylamines and methacrylates for any kind of plastics, or caprolactarme for clothing and fashion.

Multi-Combination Gauze Pack

A new gauze generation takes over catalytic ammonia oxidation: MPAC

Multi-Combination Gauze Pack builds on the success story of the already unique multi-layer gauze systems that had been introduced more than a decade ago. A much broader toolbox of new and improved features supported by a much better understanding of how to use these tools enables gauze designs that will match significantly better with defined performance criteria in ammonia oxidation processes. The most striking difference compared to our established MKS systems is the fact that MPAC allows a distinctly bigger number of combinations, designs and functionalities. Next to material and wire constitutions it is first and foremost the structural uniqueness that makes MPAC an even more effective system compared to its MKS ancestors.

The first MPAC generation will focus on improving product yield, reducing PGM weight and increasing campaign times. For certain conditions it will also be able to lower greenhouse gas emissions.

Additional features & functionalities will be gradually added over the next 24 months, making MPAC a truly vital and dynamic gauze innovation.
