Abstract

resumo processo e aparelho de granulação de ureia com sistema de depuração trata-se de um processo de granulação de ureia com sistema de depuração que inclui pelo menos uma corrente residual gasosa para a remoção de poeira e amônia, de modo que essa corrente residual é processada através de uma combinação das seguintes etapas de processo, que compreendem (a) lavar a corrente carregada de poeira e amônia (4) com água e/ou uma solução de ureia aquosa, de modo que uma corrente líquida carregada de poeira (26) e uma corrente reduzida de poeira (5) são geradas, e (b) reagir a corrente reduzida de poeira (5) com formaldeído (7) para formar uma corrente (8) que compreende hexametilenotetramina e ureia-formaldeído e gás efluente limpo (6) em que a corrente de gás é direcionada primeiro através da etapa de processo (a) e, então, através da etapa de processo (b). 1/1
