Claims (1)
1. Способ совместного получения мочевины и реагента аммиака с использованием стадий получения синтез-газа для синтеза аммиака, содержащего диоксид углерода, и конверсии синтез-газа в реагент аммиак, реакции реагента аммиака с диоксидом углерода в синтез-газе с образованием карбамата аммония и получения мочевины, который включает также стадии до конверсии синтез-газа в реагент аммиак (1) промывания синтез-газа водным раствором реагента аммиака и образования раствора, обогащенного карбаматом аммония, (2) удаления избытка реагента аммиака из промытого синтез-газа промывкой водой и извлечения водного раствора реагента аммиака, (3) очистки синтез-газа, промытого водой, удалением остаточных количеств воды и аммиака, и (4) пропускания очищенного синтез-газа для конверсии этого газа в реагент аммиак.
