Abstract
"MéTODO DE TRATAMENTO DE SOLUçõES USADAS EM PROCESSO DE PRODUçãO DE FERTILIZANTES". A presente invenção se refere a um método para fabricação de um produto sólido contendo nitrogênio e fósforo, particularmente um produto sólido de fosfato de amónio e/ou fosfato de amónio uréia, em cujo método a solução contendo uréia e ácido fosfórico é aquecida. A água depois se evapora da solução e a uréia na solução se decompõe em amónia e dióxido de carbono. O dióxido de carbono sai do reator junto com vapor d'água; a amónia gerada neutraliza o ácido fosfórico. Se obtém, então, uma suspensão contendo fosfato de amónio e/ou fosfato de amónio uréia, que é solidificada, seca, moída, triturada e/ou granulada. O produto final pode ser usado como fertilizante ou pode ser usado como parte de um fertilizante misto.
