Abstract
Способ очистки отходящих газов при получении мочевины из аммиака и диоксида углерода, в котором отходящие газы, выделяющиеся практически при атмосферном давлении из установки синтеза мочевины, сдавливают при помощи эжектора, который приводится в действие газом, который отходит со стадии синтеза при высоком давлении, и подают в абсорбер среднего давления. Давление отходящих газов повышают на 0,15-2 МПа.
