这一讲介绍了浓缩磷酸用管式反应器—转鼓造粒技术生产 MAP、DAP及 NPK肥料的流程 ,它们是 :SA Cros中和槽—管式反应器混合流程、ERT ESPINDESA单反应管流程及 AZF双反应管流程。同时还介绍了Minifos加压氨化生产粉状 MAP及 Norsk Hydro加压氨化生产粒状 DAP流程。
This talk describes the process for the production of MAP, DAP and NPK fertilizers using the concentrated phosphoric acid tubular reactor - rotary drum granulation technology. These are: SA Cros neutralization tank-tubular reactor mixing flow, ERT ESPINDESA single-reactor flow And AZF double reaction tube flow. At the same time also introduced Minifos pressurized ammonification production of powdered MAP and Norsk Hydro pressurized ammonification to produce granular DAP process.
