Claims (1)

Заявлены улучшенный способ получения мочевины, установка для его осуществления, а также способ модернизации существующего предприятия по производству мочевины на основе процесса Стамикарбон. В соответствии с изобретением к существующему оборудованию дополнительно устанавливают высокоэффективный реактор с частичным отводом тепла в узел выделения мочевины из раствора, выходящего из высокоэффективного реактора, при этом предусматривается размещение устройств для рециклирования паров непрореагировавшего аммиака и диоксида углерода, а также раствора карбамата, полученного в узле выделения мочевины в существующий реактор.An improved method for producing urea, an installation for its implementation, as well as a method for modernizing an existing urea plant based on the Stamicarbon process are claimed. In accordance with the invention, a highly efficient reactor with partial heat removal to a urea separation unit from a solution exiting a high-performance reactor is additionally installed to existing equipment, and devices for recycling vapors of unreacted ammonia and carbon dioxide, as well as a carbamate solution obtained in the allocation unit, are provided urea into an existing reactor.
