Abstract

Винахід стосується об'єднаного способу синтезу сечовини і меламіну, в якому синтез сечовини здійснюють із застосуванням способу з відпарюванням в контурі синтезу високого тиску, що включає реактор, відпарний апарат і конденсатор карбамату, причому розчин сечовини, що виходить із вказаного відпарного апарата, направляють до секції вилучення для одержання продукту - концентрованої сечовини і вилученого розчину карбамату; принаймні частину вказаного продукту - сечовини перетворюють на меламін, а відхідні гази із процесу синтезу меламіну повертають до процесу синтезу сечовини шляхом змішування з газовою фазою із відпарного апарата і з вказаним вилученим розчином карбамату, утворюючи, таким чином, змішаний потік, який потім конденсують у вказаному конденсаторі карбамату, і, зрештою, конденсат направляють до реактора.
