Abstract
<B>"MéTODO PARA MODERNIZAçãO DE UMA INSTALAçãO DE PRODUçãO DE URéIA"<D>. A presente invenção se refere a um método para modernização de uma instalação para produção de uréia, do tipo que compreende um reator (2) para síntese da uréia, uma unidade de extração (3) com dióxido de carbono e pelo menos uma unidade de condensação vertical (4), do tipo filme, onde são previstos meios (36) para alimentar uma porção principal de um fluxo que compreende amónia e dióxido de carbono na fase vapor, que deixa a unidade de extração (3), para a unidade de condensação (4) e ainda a provisão de meios (37) na dita unidade de condensação (4), para submissão a uma condensação substancialmente total da tal porção principal do fluxo que compreende amónia e dióxido de carbono na fase vapor, obtendo-se um fluxo que compreende uréia e carbamato em solução aquosa, que é depois alimentado ao reator (2) para a síntese da uréia. Graças ao presente método de modernização, a eficiência da unidade de condensação (4) é acentuadamente aperfeiçoada, permitindo, dessa forma, um aumento de sua capacidade.
