PROCESS FOR THE SYNTHESIS OF UREA COMPRISING A PASSIVATION STREAM AT THE STRIPPER BOTTOM |
摘要 |
<p>A process for the direct synthesis of urea from ammonia and carbon dioxide with increased corrosion resistance comprising in the high pressure synthesis section a reaction step in a vertical reactor (R) fed with at least one stream of fresh carbon dioxide containing a passivating agent and a decomposition stripping step of the non converted reagents wherein the gas liquid mixture collected at the head of the reactor is separated into a gaseous stream and a liquid stream fed to the tail and head of the stripper respectively.</p> |
