Ammonium sulfate and liquid ammonia

Ammonia is recovered from coke oven gas

Ammonium sulfate is a prevalently used nitrogen fertilizer, characterized by immediate effectiveness.Liquid ammonia (liquified ammonium) is widely used as a raw material for fertilizers and for denitrification.

Ammonium sulfate

Ammonium sulfate is a common fertilizer.

JFE Chemical manufactures ammonium sulfate for use as a nitrogen fertilizer by recovering ammonia from coke oven gas using sulfuric acid. According to the application, we offer a variety of products to Japanese customers. These include ammonium sulfate of various grain sizes, controlled by a crystallization process, as well as powdered ammonium sulfate.
We also apply our own innovative technology to produce large-grain ammonium sulfate for use as a straight fertilizer.
