Abstract
Изобретение относится к способу получения мочевины из аммиака и диоксида углерода на установке синтеза мочевины, в которую входят секция синтеза высокого давления и одна или более секций рекуперации, работающих при низком давлении, где секция синтеза высокого давления включает реактор, отпарной аппарат и конденсатор, причем газы, выходящие из секции синтеза высокого давления, конденсируются в конденсаторе среднего давления при 0,5-12 МПа, в который подается также карбаматный поток из одной из секций рекуперации, после чего по крайней мере часть образовавшегося конденсата подается в конденсатор высокого давления.
