Abstract
προκειμένη εφεύρεσις έχει ως αντικείμενον: 1. Μία μέθοδον παρασκευής συνθέντων λιπασμάτων υπό την μορφήν κόκκων, επί τη βάσει των μονο- και δι-αμμωνιακών φωσφορικών ενώσεων, περιλαμβάνουσαν την εξουδετέρωσιν, εις πλείονα στάδια και τη βοηθεία αεριώδους αμμωνίας, του φωσφορικού οξέος μόνου ή εν αναμίξει μετ' άλλων οξέων, και την εις κόκκους διαμόρφωσιν του προϊόντος της αντιδράσεως, η δε μέθοδος αύτη χαρακτηρίζεται εκ τούτου, ότι φέρομεν εις αντίδρασιν, εντός ενός πρώτου κάδου, το φωσφορικόν οξύ μόνον ή εν αναμίξει μετ' άλλων οξέων, και την αεριώδη ή υγράν η εν υδατικώ διαλύματι αμμωνίαν, κατά τρόπον ώστε η σχέσις ΝΗ3/ΡΟ4 εντός του κάδου τούτου να ευρίσκεται εις περίπου 0.80 εκ τούτου, ότι εντός ενός δευτέρου κάδου φέρομεν το προϊον της αντιδράσεως, το οποίον παρήχθη εντός του πρώτου κάδου, εις αντίδρασιν μετ' αμμωνίας, κατά τρόπον ώστε η σχέσις ΝΗ3/ΡΟ4 να ανέλθη εις περίπου 1.5' και εκτούτου, ότι επιτελούμεν εντός της διατάξεως διαμορφώσεως εις κόκκους, την τελικήν ρύθμισιν της μοριακής σχέσεως ΝΗ3/ΡΟ4 δια προσθήκης είτε αμμωνίας, είτε ενός οξέος. The object of this invention is: A method of preparing granular synthetic fertilizers, based on mono- and di-ammonium phosphates, comprising neutralizing, in several steps, and assisting gaseous ammonia, phosphoric acid alone or in a mixture with others. and granulation of the reaction product, and this method is therefore characterized by reacting, in a first bucket, phosphoric acid alone or mixed with other acids, and the gaseous or liquid aqueous ammonia solution. , so that the NH3 / PO4 ratio in this bucket is about 0.80, therefore, in a second bucket we carry the reaction product, which was produced in the first bucket, in a reaction with ammonia, so that the NH3 / PO4 ratio to be about 1.5 'and therefore, that we perform within the granulation device, the final adjustment of the NH3 / PO4 molar ratio by adding either ammonia let, or an acid.
