Abstract

Описан способ совместного производства двух разных карбамидных продуктов. Один продукт представляет собой водный раствор карбамида, подходящий для использования при снижении содержания NO(по существу, указан как жидкость для очистки выхлопных газов дизельных двигателей (DEF)). Другой продукт представляет собой раствор, используемый в качестве удобрения, а именно карбамидо-аммиачную смесь (КАС). Производства DEF и КАС объединены следующим образом: аммиак, извлекаемый при производстве карбамида, используют в качестве сырья для производства нитрата аммония. По меньшей мере часть водного потока карбамида, получаемого при производстве карбамида, смешивают с нитратом аммония, чтобы получить КАС.
