During the manufacture of Nitric Acid, significant quantities of pollutants are released into the atmosphere. Principal amongst these pollutants is the greenhouse gas nitrous oxide (N2O), one tonne of which has a Global Warming Potential (GWP) equivalent to 310 tonnes of carbon dioxide.
Pollution is an issue all over the world and N2O emissions from chemical plants have become increasingly under review by environmental authorities over the last decade. N2O is recognised under the Kyoto Protocol as one of the six greenhouse gases in the atmosphere in need of reduction and control, and as a result in recent years significant pressure has been put on all nitric acid producers to reduce N2O emissions.
Johnson Matthey have several secondary catalyst options for the reduction of N2O on Nitric acid and Caprolactam plants. Due to the nature of the individual plants in terms of operating conditions, period of operation, process flow Johnson Matthey look at each project independently. This method of working ensures that the greatest reduction in N2O emissions possible is achieved.
For further information on the N2O abatement catalysts available please refer to the N2O abatement section on our Noble Metals website.
