Abstract
Раскрыт способ удаления пыли карбамида из отходящего газа доводочной секции (1) установки по производству карбамида, причем способ включает выполнение гашения отходящего газа водой (06) с получением гашеного отходящего газа и выполнение очистки гашеного отходящего газа при помощи по меньшей мере одного скруббера Вентури (11). В результате этого достигается меньшее падение давления на скруббере и более эффективный рост частиц карбамида, что упрощает их удаление.
