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.
