Abstract

"INSTALAçãO E PROCESSO PARA A PREPARAçãO DE URéIA". A invenção refere-se a uma instalação para a preparação de uréia partindo de amónia e de dióxido de carbono, a instalação compreendendo duas seções do reator em um reator combinado colocado verticalmente e uma seção do condensador a alta pressão. A instalação pode compreender um reator combinado colocado verticalmente, com as duas seções de reator estando separadas por uma seção do condensador a alta pressão. Em uma outra modalidade a instalação compreende um reator combinado colocado verticalmente que compreende duas seções de reator e uma seção do condensador a alta pressão colocada do lado de fora do reator. A invenção também se refere a um processo para a preparação de uréia nesta instalação. Isto envolve a alimentação da corrente gasosa que sai do extrator completamente ou parcialmente à seção do condensador a alta pressão da instalação. Preferencialmente, uma parte da corrente gasosa que sai do lavador é alimentada à segunda seção do reator no reator combinado colocado verticalmente por meio de um ejetor acionado por amonia.
