Abstract

Oppfinnelsen angår en fremgangsmåte for fremstilling av melamin forbundet via en karbamatkonsentrasjonsenhet, omfattende en desorpsjonskolonne hvori en gasstrøm, omfattende ammoniakk, karbondioksid og vann genereres, en fremgangsmåte for fremstilling av urea omfattende en varmeveksler, hvor en urea-inneholdende strøm er til stede, hvori gasstrømmen omfattende ammoniakk, karbondioksid og vann sendes til varmeveksleren, hvori varme utveksles med den urea-inneholdende strømmen og gasstrømmen omfattende ammoniakk, karbondioksid og vann kjøles og minst delvis kondenseres for å oppnå en ammoniumkarbomatoppløsning som sendes til fremgangsmåten for fremstillingen av urea. ?? ?? ?? ?? 1
