Abstract
"PROCESSO PARA A PRODUçãO DE MELAMINA". A invenção refere-se a um processo para a produção de malamina pela pirólise da uréia em um reator de alta pressão tendo um tubo central vertical, em que a melamina flui para cima para o reator a partir de baixo, mistura-se na parte inferior do reator com um material em fusão de uréia e opcionalmente NH ~ 3~ introduzido no reator a partir de baixo, emerge do tubo central na parte superior do tubo central, uma parte da melamina formada flui para baixo no espaço anular entre o tubo central e parede de reator e a parte restante é expelida para outra produção, os de gases de descarga são removidos no topo do reator e um reator para realizar o processo.
