my country’s ammonium nitrate production capacity and output are gradually decreasing, and companies are seeking transformation

The chemical formula of ammonium nitrate is NH4NO3. It is a colorless and odorless white crystalline powder. It is easily soluble in water, easy to absorb moisture and agglomerate, and is prone to thermal decomposition. Ammonium nitrate is relatively stable at room temperature and is not sensitive to collision, blow, or friction. However, under high temperature conditions, ammonium nitrate will explode when it is violently impacted. Therefore, safety regulations must be followed during production and use. Ammonium nitrate is widely used in the production of analytical reagents, oxidants, refrigerants, fertilizers, pesticides, fireworks and explosives.

At present, my country’s ammonium nitrate production process is very mature. It mainly uses neutralization reaction for production. The solution containing anhydrous ammonia and aqueous nitric acid is placed in a pipeline reactor for reaction. The tubular reaction can be roughly divided into three types. The stages are respectively the reaction between gaseous ammonia and nitric acid, evaporation in the reactor, and granulation. The nitric acid solution produced using this method has higher purity, is simple to operate, and facilitates daily equipment maintenance, and has gradually become the mainstream ammonium nitrate production process.

According to the “Ammonium Nitrate Industry Development Prospects and Investment Strategic Planning Analysis Report 2023-2027” released by the Industrial Research Center, my country’s nitric acid The ammonium industry started late, and production lines were gradually constructed and put into operation in the 1960s and 1970s. After years of development, the types of ammonium nitrate products in my country have gradually increased, which can be roughly divided into industrial ammonium nitrate, urea ammonium nitrate solution, nitro compound fertilizer, etc. Among them, industrial ammonium nitrate can be subdivided into porous ammonium nitrate, liquid ammonium nitrate, crystallized nitric acid Ammonium etc. In recent years, my country has gradually become one of the major producers of ammonium nitrate. However, because ammonium nitrate is a dangerous and explosive substance, regulatory requirements have become increasingly strict, and it has become more difficult to approve related projects, resulting in the gradual reduction of my country’s ammonium nitrate production capacity. According to data released by the China Nitrogen Fertilizer Industry Association, in 2022, my country’s ammonium nitrate production capacity will be 10.42 million tons and output will be 5.959 million tons, a year-on-year decrease of 3.9% and 1.0% respectively.

In recent years, due to the increasingly strict national safety control requirements, the number of ammonium nitrate companies in my country has gradually decreased. At present, my country’s largest ammonium nitrate production companies mainly include Jinkai Chemical, Huafeng Chemical, Jinxiang Sairui Chemical, Xinghua Group, Jiuding Chemical, Hualu Hengsheng, Tianji Coal Chemical, Yunnan Jiehua, etc. At this stage, my country’s ammonium nitrate companies are continuously adjusting their product structure and seeking corporate transformation.

Industry analysts said that in order to solve the problem of ammonium nitrate storage capacity, ammonium nitrate companies have gradually reduced the production capacity of ammonium nitrate and switched to other chemical products. . Due to the growing demand for nitro fertilizer products in the agricultural field, nitro fertilizer products such as nitrophosphate fertilizer, calcium nitrate, and ternary nitro compound fertilizer are widely used. Therefore, the product structure of the ammonium nitrate industry is gradually adjusted. And as my country’s ammonium nitrate production technology gradually improves, backward ammonium nitrate production capacity gradually withdraws from the market, the industrial structure continues to be optimized, and gradually develops in the direction of environmental protection, standardization, and high-end.
