Abstract

Раскрывается способ получения мочевины из аммиака и диоксида углерода, в котором отходящие газы, выделяющиеся, практически, при атмосферном давлении с установки синтеза мочевины, сжимают с помощью эжектора, приводимого в движение газом, отходящим со стадии синтеза при высоком давлении, и подают в абсорбер среднего давления. Давление отходящих газов повышают на 0,15-1 МПа.Международная заявка была опубликована вместе с отчетом о международном поиске.
