Ozone is useful when situated in the atmosphere for controlling solar irradiation. The emission of ozone at ground level is however an issue and lead to health problems. Hulteberg has developed an effective catalyst formulation for handling ozone and also perform reactor and system design for this particular emission, drawing on experience from several references.

As is the case with abatement of volatile organic compounds, the abatement of ammonia is intimately coupled to our catalyst production. When using nitrate salts in the production NOx is the primary emission, this is handled by dosing ammonia/urea over a selective NOx reducing catalyst. To ensure high levels of conversion a surplus of ammonia is dosed and decomposed downstream the NOx removal. As the catalyst production is performed in batch mode, the emission levels are varying with time and therefore presents a challenging task for emission control. This experience has however prepared us for system design in particularly difficult situations with large variations in ammonia emission levels during normal operation and multiple start/stop scenarios.

Nitrous oxide is a severe greenhouse gas, 300 times worse than carbon dioxide, as well as acting as an ozone depletion agent. At Hulteberg we have catalyst material that convert the nitrous oxide to environmentally benign compounds and we will be happy to help you assess your application as well as design a solution for you.

Please don’t hesitate to contact us if you have any problems that seem out of the ordinary and you don’t know who to ask. We have solved “impossible” chemical engineering task for years and are happy to help you in all your undertakings, small or large. To exemplify we have developed software for basic design of amine scrubber systems, developed and constructed hydrogen burner systems with the option of nitrous oxide mixing into the flame for heat treatment and analysed transport properties of water in lithium chloride under vacuum.

Hydrogen technology is part of our legacy. We have designed catalysts, reactors and systems for more than 15 years in this particular field. Much of the work has been focused on the development of hydrogen generators for fuel cells, but also hydrogen combustion, desulphurisation and hydrogen generation from biomass have been parts of the work.
