1. Ammonia application

Ammonia has a wide variety of uses.

Fertilizer: It is said that 80% or more of the uses of ammonia are fertilizer uses. Starting from urea, various nitrogen-based fertilizers such as ammonium sulfate, ammonium phosphate, ammonium chloride, ammonium nitrate and potassium nitrate are produced using ammonia as a raw material. In North America, there are many fertilization methods in which liquid ammonia is directly sprinkled onto the soil.

Chemical raw material: It is a raw material for various chemical products containing nitrogen atoms, and is made into resins, food additives, dyes, paints, adhesives, synthetic fibers, synthetic rubbers, fragrances, detergents, etc.

Denitration: It is installed in boilers of thermal power plants to suppress the generation of nitrogen oxides(NOx) that are harmful to the environment.

Fuel for thermal power generation: Ammonia burns depending on conditions, and carbon dioxide does not generate when ammonia is burned. For this reason, technology development using ammonia as fuel for thermal power generation is being carried out.

nergy (hydrogen) carrier: Since liquefying ammonia requires less energy than liquefying hydrogen, it is being studied as one of energy and hydrogen storage or transportation means. In addition, some companies are working on the development of fuel cells that directly extract energy from ammonia.

1. Ammonia production technology

1.1 The raw materials for the production of synthetic ammonia are mainly coke, coal, natural gas, heavy oil, light oil and other fuels, as well as water vapor and air.

1.2 Ammonia synthesis process: Raw material → preparation of raw gas → desulfurization → transformation of carbon monoxide → decarbonization → removal of a small amount of carbon monoxide and carbon dioxide → compression → synthesis of ammonia → product ammonia.
