Abstract

В заявке описан способ комплексного получения мочевины и меламина, при котором мочевину получают на установке (10) для получения мочевины, которая включает секцию (11) синтеза мочевины при высоком давлении, из которой выходит водный раствор, содержащий мочевину, карбамат аммония и аммиак, и секцию (21) извлечения мочевины при низком давлении, а меламин получают на установке (40) для получения меламина, который отличается тем, что отходящие газы, которые являются побочным продуктом технологического процесса синтеза меламина, отводят от установки при среднем давлении и подают на повторный цикл в секцию (11) синтеза мочевины при высоком давлении. Также описана комплексная установка для получения мочевины и меламина.
