Fertilizers containing micronutrients compositions and Methods for their Preparation

摘要

Claim 1: a method for producing a granular Fertilizer that comprises at least one Primary Nutrient and at least a Micronutrient, characterized in that it comprises Introducing the starting ingredients in a reactor or in a pre Neutralizer.Where the starting Ingredients undergo a Chemical Reaction to form a suspension; remove and capture a Waste gas from the Reactor or pre Neutralizer, where the waste gas contains Ingredients which have not reacted; Purge gas Waste Water in a device for processing the waste gas.So as to generate a stream of return Water in which they are dissolved Ingredients which have not reacted; Introducing at least one Micronutrient dissolved into the water stream to reintroduce the flow return; return Water in the Reactor or in the pre neutraliz Designer; combining the current return water with suspensionSo as to incorporate at least one dissolved in the suspension Micronutrient Fertilizer Granules; and form from the suspension, so as to distribute at least one Micronutrient Fertilizer dissolved in the Granules.Claim 2: The Method according to claim 1, wherein the at least one selected from the Group comprising Micronutrient Boron, Copper, Iron, Manganese, Molybdenum, zinc, Cobalt, Sodium chlorine, and combinations of these.Claim 9: The Method according to claim 1, characterized in that it also involves introducing a source of Sulfur in the granulation Drum, where the fertilizer Granules are coated with Sulphur Source.Claim 1: a method for producing a granular Fertilizer composition comprising at least one Primary Nutrient and at least a Micronutrient, characterized in that it comprises Introducing the starting ingredients in a reactor or in a pre Neutralizer.Where the starting Ingredients undergo a Chemical Reaction to form a suspension; Dissolving at least one Nutrient at a current of Phosphoric Acid; Phosphoric acid combined with the flow of the suspension to optimize the molar ratio between the ingredients of P Artida; granular And Suspended in a Granulator, so as to form the fertilizer Granules.Claim 22: The Method according to claim 11, wherein the starting Ingredients include Ammonia and Phosphoric Acid, which react to form a suspension of Ammonium phosphate.Claim 23: The Method according to claim 22, wherein the starting ingredients are introduced into the Reactor or in the pre Neutralizer with a molar ratio between n and P between 0.3 and 0.9, so that they form monoammonium phosphate (MAP).Claim 24: The Method according to claim 22, wherein the starting ingredients are introduced into the Reactor or in the pre Neutralizer with a molar ratio between n and P between 1.1 and 1.7, which form diammonium phosphate.
