With the promulgation and implementation of the Regulations on the Management of Hazardous Chemicals, China has strictly regulated and restricted the production, sale, transportation, storage and use of hazardous chemicals. Ammonium nitrate has been banned from being sold as fertilizer. The ammonium nitrate production plant of many domestic enterprises has therefore been in a state of suspension of production, causing huge losses to the enterprise. In 2002, PetroChina Co., Ltd. entrusted the University of Petroleum to undertake a research and development project for the modification of agricultural ammonium nitrate. In December 2003, the technology passed the expert appraisal organized by PetroChina Co., Ltd., and the small test samples were tested by the National Civil Explosive Inspection Center for good explosion-proof performance. The modified ammonium nitrate produced by this process has also passed the test of the National Civil Blasting Equipment Inspection and Testing Center and the Soil and Fertilizer Institute of the Chinese Academy of Agricultural Sciences in September this year.
In order to make this technology into industrial production as soon as possible, the research team cooperated with the chemical fertilizer plant of Jilin Petrochemical Company to carry out the industrialization test of modified ammonium nitrate based on its existing ammonium nitrate production equipment. The test results show that the ammonium nitrate product produced by this technology has the characteristics of high particle strength, high nitrogen utilization rate, explosion-proof, moisture-proof and anti-caking comprehensive performance, which can not only reduce the explosive performance of ammonium nitrate, but also increase the efficiency of ammonium nitrate. At the same time, it does not cause any side effects on soil, environment and crops. Ammonium nitrate is a single-effect fertilizer and cannot be compared with compound fertilizer, especially at a price.
At present, Jilin Petrochemical Company is actively preparing for industrial production and is expected to officially start production at the beginning of next year. According to the estimation of 200,000 tons/year of production, considering the preferential policies of local governments for fertilizer production, only one Jilin Petrochemical Company can increase the benefits by tens of millions of yuan.
Explosion-proof ammonium nitrate technology breakthrough
Ammonium nitrate, which has been banned for sale after the promulgation of China's Regulations on the Management of Dangerous Chemicals, will be lifted with the birth of explosion-proof ammonium nitrate modification technology. It is understood that the industrialization test of the research topic of explosion-proof ammonium nitrate modification technology, which was presided over by Associate Professor Zhao Dongfeng of the College of Chemistry and Chemical Engineering of the University of Petroleum (East China), was successful in the chemical fertilizer plant of Jilin Branch. This move will bring good news to the ammonium nitrate enterprises in China that are in a state of suspension.
