What is Ammonia?

• Ammonia is a combination of the two gaseous elements hydrogen and nitrogen.
• The bond ratio of three hydrogen molecules to one nitrogen molecule is formed.
• The chemical formula of ammonia Is NH3.

Ammonia storage and transport tanks:

• Moisture-free (dry) ammonia is available in the form of pressurized gas in cylinders, cryogenic tanks, and non -cryogenic tanks.
• Also, dry ammonia is stored in bulk tanks with a large volume and installed on the ground.
• The large storage tanks, which are not usually installed on the ground, have very low pressure and have a cooling cycle as well as thermal insulation.

Ammonia grades:

Acceptable grades used in various industries are:

Almost %80 of the total ammonia produced is used in the fertilizer industry.

Safety precautions

1. People with chronic illnesses or long-term allergies should not be hired where there is ammonia.
2. Ammonia ions are in fact a phenomenon of the biological system, yet ammonia in the atmosphere has a very stimulating effect on the mucous membranes of the eyes, nose, throat, and lungs.
3. Too much ammonia can have destructive effects on tissues.
4. Too much ammonia can lead to laryngeal and bronchial problems.
5. Too much ammonia can cause edema and Obstruction of breathing.

Compatible and incompatible materials:

• Ammonia doesn’t affect most metals without moisture.
• When ammonia combines with water vapor; Affects copper, zinc, and their alloys.
• The use of copper, zinc, silver, and their alloys in the manufacture of ammonia tanks is prohibited.
