[ 49. A system for the production of ammonium sulfate granules, the system comprising:
a pipe cross reactor (PCR) configured to contact concentrated sulfuric acid with ammonia to produce a PCR product comprising ammonium sulfate; and
a granulator fluidly connected to the PCR, whereby PCR product from the PCR can be introduced into the granulator, and comprising an inlet for ammonium sulfate seed material, ammonia spray nozzles configured to spray anhydrous ammonia inside the granulator to contact ammonium sulfate granules within the granulator, and a granulator product outlet configured for extraction of granulator product comprising ammonium sulfate granules from the granulator;
wherein the pipe cross reactor comprises a discharge section located internal to the granulator, and configured to introduce the PCR product into the granulator. ]
