The utilization of the waste sodium nitrate to a new mineral fertilizers production

During the processes of various types of catalysts production, waste sodium nitrate solutions are generated. Until recently they were utilized during the production process of potassium nitrate. Because new and cheaper methods of this substance production are developed, Zaklady Azotowe w Tarnowie-Moscicach S.A. are forced to develop another method of waste sodium nitrate solutions utilization. As a result of the performed research it has been found out that they may be used during the saltpetre fertilizers production.
