Preparation method of ammonia gas or liquid ammonia

[Physical and chemical properties] Ammonia is a colorless gas or liquid with a strong pungent odor

Ammonia gas is easily soluble in water.

[Preparation method] The main raw materials are coal (or coke, natural gas, etc.

N ₂ +3H ₂ =2NH ₃

After the reacted gas is lowered in temperature by the heat exchanger, it is led out from the outlet at the bottom of the tower

At present, most ammonia synthesis systems are operated in a single tower, and a few adopt multiple towers in parallel

[Application] Ammonia is a low-toxicity category

Ammonia can be used as a regulator of the pH value of boiler feed water to neutralize the carbonic acid in the feed water, increase the pH value of the solution, and slow down the corrosion of carbon dioxide in the feed water

It can also be used as a boiler shutdown protective agent

Moreover, preparation can be used ammonia, nitric acid, amine salts, nitrogen and the refrigerant, anti-rust agents
