manufacture of ammonia by the Haber Process chemguide
Why is ammonia important? About 85% of ammonia produced is used to make nitrogen fertilisers like ammonium nitrate or ammonium sulfate. About 5% is used to make nitric acid. Most of this is also used to make fertilisers (for example, ammonium nitrate), but some is used in the manufacture of things like explosives, dyes, and some In the US, there are only 16 companies that manufacture ammonia, and 60% of US production is concentrated near the Gulf of Mexico. This centralized ammonia manufacturing system relies on global imports to meet the demand for ammonia fertilizer as well as long-distance transportation to bring the ammonia to farmlands.Major Ammonia Producing Companies and Their Capacities

Ammonia (NH3) Ammonia Structure, Preparation,
Ammonia is lighter than air with a density of 0.769 kg/m 3 at STP. It is widely used as a fertilizer. It is also used in the manufacturing of explosives such as nitrocellulose and TNT. Also, it is used in the production of soda ash and in the Ostwald process to get nitric acid.ammonia at relatively low costs. As recently as 80 years ago, the total annual production of synthesized ammonia was just over 300,000 m.t. Thanks to chemical engineering break-throughs, one modern ammonia plant can produce more than 750,000 m.t./yr. Approximately 88% of ammonia made annually is con-sumed in the Introduction to Ammonia Production AIChE

Green ammonia Royal Society
Ammonia is a pungent gas that is widely used to make agricultural fertilisers. Green ammonia production is where the process of making ammonia is 100% renewable and carbon-free. One way of making green ammonia is by using hydrogen from water electrolysis and nitrogen separated from the air. These are then fed into the Haber Ammonia production is one of the largest industrial processes, and is currently responsible for over 1.5% of global greenhouse gas emissions. Decarbonising this process, yielding ‘green ammonia’, is critical not only for sustainable fertilizer production, but also to unlocking ammonia's potential as a zero-carbon fuel and hydrogen store.Facilitating green ammonia manufacture under milder

Preparation and Manufacture of Ammonia (Haber's Process)
Manufacture of Ammonia: Ammonia is usually prepared on a commercial scale from its elements hydrogen and nitrogen by Haber’s process. The reaction involved is-N 2 + 3H 2 ⇌ 2NH 3: Haber’s Process: In this process, a mixture of N 2 and H 2 in the ratio of 1:3 by volume is compressed to 200-900 atmospheres. The compressed gaseous Ammonia is the second-largest global chemical products, utilized as agricultural fertilizer, food production, industrial materials, refrigerants, and additives.
