Abstract

Patente de Invenção: "MéTODO DE REDUçãO DE DENSIDADE POR MEIO DE AGENTE GERADOR DE GáS". Esta invenção refere-se a um método para reduzir densidade em um produto de nitrato de amónio. O método compreende proporcionar um agente gerador de gás em forma de um composto sólido insolúvel em água capaz de gerar gás através de reações químicas, e proporcionar um produto de nitrato de amónio. O agente gerador de gás sólido insolúvel em água é introduzido no produto de nitrato de amónio sob condições que causam geração de gás através do agente gerador no produto de nitrato de amónio. O produto de nitrato de amónio é particulado para formar um produto de nitrato de amónio particulado em forma de prills com densidade reduzida. A invenção também refere-se a um produto de nitrato de amónio particulado produzido por este método e ao uso de um agente gerador de gás em forma de um composto sólido insolúvel em água para reduzir densidade em um produto de nitrato de amónio particulado.
