Abstract
Методът създава възможност в зоната за кондензация да се получи поне 30% от равновесно достижимото количество карбамид за условията на реакцията, като сместа, съдържаща карбамат и карбамид, се отвежда към зоната за синтез. Предпочита се получаванетона карбамид да продължава, докато се получат от 50 до 80% от равновесното количество. По метода разтворът за синтез, съставен от карбамат и свободен амоняк, се образува от въглероден диоксид и излишък на амоняк при налягане 125-350 бара, като поне част от карбамата, съдържащ се в разтвора, се разлага в дестилационната зона при налягането на зонатаза синтез или при по-ниско налягане чрез подаване на топлина и при контакт в противоток с очистващ газ. Продуктите от това разлагане,част от излишъка от амоняк и очистващият газ се отстраняват от дестилационната зона като газова смес и най-малко частот тази смес се кондензира в зоната за кондензация. Очистеният разтвор за синтез на карбамид се превръща в разтвор на карбамид или твърд карбамид. 6 претенции, 1 фигура
