TR TR DESCRIPTION IMPROVEMENT OF THE CAKEING PROPERTIES OF AMMONIUM NITATE WITH ZINC BORATE, BENTONITE AND COLEMANITE Technical Field to which the invention relates: This invention aims to prevent ammonium nitrate particles from sticking together and losing their physical properties by reducing the moisture absorbing properties during the storage of ammonium nitrate, which is the most used nitrogenous fertilizer in the nitrogen fertilizer industry. zinc to the process It is related to the addition of borate (13), bentonite (12) and colemanite (11). State of the Art In the nitrogen fertilizer industry, the demand for the production of ammonium nitrate fertilizer, which is used for the needs in agricultural areas, is increasing day by day. When ammonium nitrate is stored after production, the problem of particles sticking to each other occurs due to the high moisture absorption potential of ammonium nitrate. Eliminating the hygroscopic properties of ammonium nitrate involves adding chemicals to the reaction medium during production that will limit its hygroscopic properties. When producing ammonium nitrate, the water it contains is evaporated by evaporation method to reach the targeted concentration and the process consists of producing concentrated ammonium nitrate. Technical Problems Aimed at by the Invention It is aimed to reduce the high moisture absorption due to the nitrate content as a result of granulation along with the production of ammonium nitrate fertilizer by adding bentonite (12), colemanite (11) and zinc borate (13) and to reduce the tendency to stick together during storage. Explanation of Figures Figure 1. Ammonium nitrate production by evaporation method concentrated ammonium nitrate: Ammonium nitrate dilution tank 11 colemanite addition line 12: bentonite addition line 13: zinc borate addition line 14: Granulation process: final product tank Description of the Invention The invention is after the production of ammonium nitrate In the dilution stage (10), along with granulation (14), zinc borate (13), bentonite (12) and colemanite (11) are added to limit the moisture absorption and reduce the tendency to stick. During the production of concentrated ammonium nitrate (9) by the evaporation method (8), anhydrous ammonia (1) is turned into gas (3) in an ammonia heater (2) and then produced with nitric acid (4) in a U type reactor (5). 6) is carried out. The ammonium nitrate (6,7) formed as a result of this reaction has a concentration of 70-80% and the concentration of ammonium nitrate is increased by concentrating it with the evaporation method (8) (9). After the targeted ammonium nitrate concentration (10) is achieved as a result of the process, anti-caking chemical additives (11,12,13) can be added in order to reach the targeted particle properties in the process. After the chemical additives added to the process in order to gain the desired properties, they are granulated (14) and stored by giving the final product properties (15,16) to the ammonium nitrate particles. Application of the Invention to Industry: The invention consists of bentonite (12), colemanite (11) and zinc borate added to the process medium after the reaction (5) of anhydrous ammonia (1) and nitric acid (4) solutions to produce ammonium nitrate, in order to improve the storage properties of ammonium nitrate. It includes the addition of additives such as (13). TR TR
