12.05.2003 - In 2000, a customer ordered a complete nitric acid train from MAN Turbo. The machinery train, which operates according to the dual-pressure process, comprises an axial air compressor, a centrifugal nitrous gas compressor, a steam turbine and an off gas expander. The plant was commissioned successfully in 2002.

Nitric acid is an important basic material for products in the chemical and fertilizer industry. Various production methods are used. Ammonia oxidizes with the aid of platinum catalysts. The nitrogen oxides contained in the combustion gases are converted almost completely to nitric acid using water in an absorber.

The project demonstrates MAN Turbo’s long-standing experience of the production of complete machinery trains and the successful operation of these plants.
