The manufacturing of CAN is a complicated and technical series of steps that typically begins with the production of concentrated ammonium nitrate from ammonia and nitric acid, then mixed with a calcium-supplying material (such as lime or dolomite) or calcium nitrate. The mixture is either granulated or prilled, dried, screened to size, cooled, and coated with anti-caking agents to ensure it will flow during storage.<\/p>\n\n\n\n
Modern manufacturing plants have placed more emphasis on energy efficiency and emissions control through various methods, such as heat recovery and treatment of vapors or other processes to limit environmental impact. Newer technologies, including the use of low-carbon or “green” ammonia as a feedstock, are beginning to influence the economics and emissions of new facilities.<\/p>\n\n\n\n
