Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania nawozów fosforowych typu superfosfat potrójny w drodze reakcji substratu fosforytowego oraz kwasu ortofosforowego(V), w którym substrat fosforytowy stanowi mieszanina rozdrobnionej, naturalnej skały fosforytowej o zawartości P2O5 co najmniej 37% (m/m) i popiołu powstałego z monospalania osadów ściekowych, o zawartości P2O5 co najmniej 27% (m/m), zmieszanych w takich proporcjach, by substytucja związków fosforu wprowadzonych do środowiska reakcji przez skałę fosforytową, związkami fosforu wprowadzonymi przez popiół z osadów ściekowych wynosiła od 10% do 70% (m/m). Substrat wprowadza się do kwasu ortofosforowego(V), o stężeniu od 28% do 32% w przeliczeniu na P2O5, podgrzanego do temperatury nie niżej niż 55°C, nie wyższej niż 65°C, porcjami, przy stałym mieszaniu, aż do wprowadzenia całości surowca, przy czym reakcję prowadzi się przy nadmiarowym stosunku kwasu do surowca wynoszącym od 1,1:1 do 1,2:1, w otwartych naczyniach reakcyjnych, utrzymując temperaturę środowiska reakcji w przedziale od 90°C do 100°C, mieszając okresowo, aż do momentu zestalenia się produktu reakcji w postaci pulpy.The subject of the application is a method for producing phosphate fertilizers of the triple superphosphate type by reaction of a phosphate rock substrate and orthophosphoric acid (V), wherein the phosphate rock substrate is a mixture of crushed, natural phosphate rock with a P2O5 content of at least 37% (m/m) and ash resulting from the mono-combustion of sewage sludge with a P2O5 content of at least 27% (m/m), mixed in such proportions that the substitution of phosphorus compounds introduced into the reaction environment by the phosphate rock with phosphorus compounds introduced by the ash from sewage sludge is from 10% to 70% (m/m). The substrate is introduced into orthophosphoric acid (V), with a concentration of 28% to 32% in terms of P2O5, heated to a temperature of not less than 55°C, not higher than 65°C, in portions, with constant stirring, until all the raw material is introduced, wherein the reaction is carried out with an excess ratio of acid to raw material ranging from 1.1:1 to 1.2:1, in open reaction vessels, maintaining the temperature of the reaction environment in the range of 90°C to 100°C, stirring periodically, until the reaction product solidifies in the form of a pulp.
