This paper is an account of the measures taken to reduce nitrous oxide (N<sub>2</sub>O) emissions at BASF Aktiengesellschaft in Ludwigshafen.
The N<sub>2</sub>O problem in general and the impact of N<sub>2</sub>O on the environment are described.
The integration between the adipic acid plant and the nitric acid (HNO3) plant at Ludwigshafen is the basis for the incorporated N<sub>2</sub>O decomposition unit for the off-gas from the adipic acid manufacture.
The last Section describes the testing of N<sub>2</sub>O decomposition in nitric acid manufacture and presents the first results.
