Fertilisers play a central role in supplying the steadily growing world population with food. Without technical gases such as nitrogen and hydrogen for ammonia synthesis, and other gas applications for the resulting fertilisers, this would not be possible. Messer supports you with expert knowledge and know-how when it comes to optimising existing plants. For example, the plant capacity of nitric acid plants can be increased by using oxygen and it is possible to increase the efficiency and reduce NOx emissions.
