Fertilizer production

In the fertilizer production (DAP,NP,NPK) process, the basic reactions take place between ammonia and acids. In this process, liquid ammonia is used between +4 and +10 °C. In addition, phosphoric acid, which has a density of approximately 1.65 g/cm³ and contains 50-52% P2O5 and 4-5% H2SO4, is also added to the reaction.

Diammonium phosphate (DAP) fertilizer production is produced by reacting the DAP and monoammonium phosphate (MAP) mixture solution, which is formed by neutralizing liquid or gaseous ammonia with phosphoric acid in pipe or tank reactors, with liquid ammonia in the granulation drum. At the end of the production process, in order for the DAP fertilizer obtained to have the desired physical properties, drying, screening/crushing, cooling and coating processes are applied respectively and the final product is taken to stock storage.

In the granulation drum, not only the chemical reaction takes place, but also the granulation process is carried out. In order to ensure proper granulation in fertilizer production, the solid-liquid balance must be kept at a certain ratio. This ratio is approximately 4:1 for DAP fertilizer production; in other words, 4 tons of return product must be used to obtain 1 ton of final product.
