Abstract
PROCESSO PARA O PREPARO DE URéIA A invenção se refere a um processo para o preparo de uréia a partir de amónia e dióxido de carbono em uma usina de uréia que contém uma seção de síntese de alta pressão e uma ou mais seções de recuperação em uma pressão menor, a seção de síntese de alta pressão compreendendo um reator, um extrator e um condensador, com os gases que deixam a seção de síntese de alta pressão sendo condensados em um condensador de média pressão a 0,5 -12 MPa ao qual também uma corrente de carbamato de uma das seções de recuperação é fornecida, após o que pelo menos uma parte do condensado formado é fornecida ao condensador de alta pressão.
