Ammonia production

Beginning with Girdler Chemical, Inc. in 1939 and Catalyst and Chemical Inc. 1957, the Süd-Chemie Group of catalyst companies has been the leading supplier of catalysts to ammonia plants for years. The production of ammonia involves the use of several key unit operations for which Süd-Chemie supplies catalysts. They are feedstock purification, primary reforming, secondary reforming, high and low temperature shift conversions, methantion, and ammonia synthesis.
