Ammonia

Ammonia (NH₃) is normally available in cylinders and drums, although we can provide it in semi-bulk in some markets.

Packaged ammonia is used by a variety of industries for a wide range of applications. Typically this includes:

• Chemicals: Neutralising acid constituents of crude oil during the refining process.
  
  
• Power & energy: Purification of smoke gas in coal fired or oil fired power plants. With the presence of ammonia in a reactor the nitrogen oxides are converted into nitrogen and water while passing the reactor. In combination with chlorine, ammonia is also used for water purification.
  
  
• Food & beverage: As a source of hydrogen for hydrogenation of oils and fats.
  
  
• Mining & metallurgy: Extraction of copper, nickel and molybdenum from their ores. Also used as a protective atmosphere for metal heat treatment. For this process ammonia is 'cracked' in a furnace to produce a reducing atmosphere of hydrogen and nitrogen.
  
  
• Pharma & biotechnology: Ammonia is used as a processing agent in the manufacturing of pharmaceuticals.
  
  
• Pulp & paper: Substitute for calcium in the pulping of wood.
  
  
• Heating ventilation & air conditioning: A natural refrigerant, often used in large industrial refrigeration systems. 
   
• Rubber & plastics: Ammonia is used in the rubber industry for stabilisation of raw latex to prevent coagulation during transportation and storage.
  
  
• Electronics: High purity ammonia is used for electronic and semiconductor applications.
