Title: COMBINED REACTOR FOR HIGH-PRESSURE SYNTHESIS OF MELAMINE
Abstract:
A reactor and associated process for the high-pressure synthesis of melamine from urea, comprising a primary step of conversion of the urea into crude melamine inside a first chamber delimited by a shell inside a reactor body and a secondary step of stripping said crude melamine melt inside a second reaction chamber, which is coaxial with and situated outside said first chamber, inside the same reactor body.
