    摘要: A system for the production of ammonium sulfate granules including a pipe cross reactor (PCR) configured to contact concentrated sulfuric acid with anhydrous ammonia to produce a PCR product comprising ammonium sulfate; and a granulator fluidly connected to the PCR, whereby PCR product extracted from the PCR can be introduced into the granulator, an inlet for ammonium sulfate seed material, an ammonia sparger configured to spray liquid anhydrous ammonia directly onto a bed of ammonium sulfate granules within the granulator, a granulator vent configured for extraction of a vapor comprising unreacted ammonia from the granulator, and a granulator product outlet configured for extraction of granulator product comprising ammonium sulfate granules from the granulator. A method of producing ammonium sulfate granules is also provided.
