Abstract
Sposób polega na tym, że reakcję rozkładu surowca fosforowego prowadzi się roztworem reakcyjnym zawierającym od 1,5 do 4,0 mola mocznika na 1 mol kwasu siarkowego, w ilości odpowiadającej od 90 do 100% kwasu w stosunku do zapotrzebowania stechiometrycznego na całkowity rozkład fosforytu, przy czym do środowiska reakcji wprowadza się wodę w ilości niezbędnej do zapewnienia jej zawartości w pulpie procesowej w zakresie 16 - 25% w odniesieniu do całej masy zawiesiny, a otrzymaną pulpę procesową kieruje się bezpośrednio do węzła granulacji. Instalacja w wersji podstawowej zawiera reaktor-mieszalnik (1) do wytwarzania roztworu reakcyjnego, układ dwóch reaktorów (3a i 3b) przygotowanych do pracy naprzemiennej, zestaw granulatorów (5), suszarkę obrotową współprądową na ogrzane powietrze lub spaliny (6), zestaw sit (7) oraz układ zawrotu zawierający młyn (13) i zbiornik buforowy (14). Sposób i instalacja szczególnie nadają się do wytwarzania nawozu USP w procesie ciągłym i pozwalają na uniknięcie czaso- i kosztochłonnych operacji związanych z dojrzewaniem produktu.
