Abstract
In un procedimento per la produzione in continuo di percarbonato di sodio in granuli di migliorata stabilità, flussi indipendenti di una soluzione acquosa di carbonato di sodio e rispettivamente di una soluzione acquosa di perossido di idrogeno, vengono alimentati in un turboessiccatore-granulatore di tipo tubolare, nel quale vengono in intimo contatto in uno strato sottile acquoso, dinamico e turbolento reagendo per dare percarbonato di sodio, successivamente granulato con un flusso di aria riscaldata a 150-200°C.
