Definitions
- Non-Explosive and Non-Flammable Ammonium Nitrate Nitrogen Fertilizer is a chemical fertilizer dedicated mainly to the nitrogen input for the soil amendment in the agricultural sector while having the ability to be marketed in the form of granules, solid.
- This fertilizer is aimed at achieving a definitive solution to the safety problem arising from the risks of explosion and self-incineration of nitrogenous chemical fertilizers as well as their uses for making explosives. by terrorists.
- Several solutions have also been explored for the risks of contamination of ground water tables and the release of gaseous pollutants while attempting and trying to limit them, contain and limit their effects.
- this product seeks to enable the chemical fertilizer industries to have much more flexibility vis-à-vis Nitrogen levels in currently commercialized products on the market while helping to facilitate the granulation phase which can be of great value to the industry from marketing points of view and the satisfaction of different customer needs; this, saving energy and profit.
- the present invention is derived from a manufacturing process specially designed for this product which amounts to the polymerization (complexation) of urea with formaldehyde in an acid catalyzed ammonium nitrate solution, the production of which is carried out as follows:
- the essential thing is to have an aqueous mixture of these three substances without the urea and formaldehyde being mixed, alone, for a sufficient time at the initiation of any polymerization reaction.
- the initial mixture of urea, ammonium nitrate and formaldehyde or formaldehyde can be made from these substances in pure form or industrial grades: Ammonium nitrate (33% N); Urea (46% N) and Formol (37.5%) or other concentration.
- the final product can contain between 30 and 40% nitrogen after drying because the initial mixture can accommodate moderate variations in the mass percentages relative to its compounds.
- the proportion of formaldehyde to urea allows only a very slight change while the proportion of ammonium nitrate can tolerate larger variations.
- the proportion of ammonium nitrate must not be excessive in order to maintain the flammability of the final product and its uselessness in the manufacture of explosives for terrorist purposes.
- the reaction is catalyzed essentially by the acids.
- the catalyst acid of the reaction may be weak, strong or a mixture; however, a weak and / or dilute acid gives a more malleable paw that can facilitate the granulation of the product while a strong and / or concentrated acid limits the reaction time. It is strongly recommended not to use acids that give salts that can deteriorate the quality of the fertilizer.
- the mixture, after the addition of the catalyst, may or may not require moderate agitation according to the industrial manufacturing techniques used; if the mixture flows immediately after the addition of the catalyst, then a metered pumping of the latter is sufficient.
- the expectation of the end of the reaction varies enormously with the quantity, the nature and the concentration of the catalyst used.
- Drying is optimal around 50 ° C or less; but, can be done in higher temperatures to the extent of the acceleration of the procedure while taking into account the generation of low release of gases containing nitrogen.
- the invention is characterized by non-flammability and its sterile and inactive nature with respect to its use as an explosive or explosive manufacturing ingredient; this fertilizer can not be used for terrorist purposes or cause explosions accidents following self-incineration such as ammonium nitrate.
- the procedure, which contributes to a very good quality, envisaged for the manufacture of this product includes the steps listed as follows:
- said invention titled “Non-Explosive Ammonium Nitrate Fertilizer and Non-Flammable” is a chemical fertilizer that modifies the soil by nitrogen in various forms, ammonium ions and nitrates, for a duration greater than those common fertilizers (Ammonium Nitrate and Urea) without risk of self-incineration and explosion.
- this product reduces the risk of groundwater contamination by drainage of chemicals through precipitation and release of harmful gases such as ammonia and NO x .
