Free Ebooks Ammonia and Urea Production

Ammonia and urea are two chemicals which are very important. This article covers a process used by Petrochem in Kapuni, South Taranaki, to synthesise ammonia from natural gas and air, then synthesise urea from this ammonia and carbon dioxide.

As has been stated above, most of the ammonia is used on site in the production of urea. The remainder is sold domestically for use in industrial refrigeration systems and other applications that require anhydrous ammonia. The urea is used as a nitrogen-rich fertiliser, and as such is of great importance in agriculture, one of New Zealand's major industries. It is also used as a component in the manufacture of resins for timber processing and in yeast manufacture.
