Urea synthesis with pool reactor (Stamicarbon's Urea 2000plusTM technology)

Building on the pool condenser process, the horizontal pool reactor, first introduced by Stamicarbon in 1996, represents the next step towards full integration of equipment in a urea synthesis plant.

By combining the functions of the urea reactor and the carbamate condenser in one vessel, the number of high-pressure components in the synthesis unit has been reduced from four to two (separator and pool reactor), thereby also eliminating a significant amount of interconnecting high-pressure piping.

The condenser unit of the reactor contains the U-tube bundle already used in the pool condenser technology, while the rest of the pool reactor forms the reaction zone for the dehydration of the carbamate.
