Abstract
Десорбер (S) для розкладання карбамату і вилучення аміаку плюс діоксиду вуглецю з розчину сечовини (U) виконаний як кожухотрубний теплообмінник, де падаюча плівка рідини розчину сечовини і протитечія газового потоку очисного середовища нагнітається в рукав труб з поверхнею, що нагрівається (6); очисне середовище, таке як діоксид вуглецю розподіляється всередині труб (6) за допомогою множини газових стояків (32); газові стояки переважно сполучені з перфорованим піддоном (30) в нижній камері (11) десорбера. Також розкрито перебудову звичайного СОдесорбера.
