摘　　要：海洋石油富岛有限公司的中小颗粒尿素造粒装置采用GGT公司(荷丰公司)CRT技术(冷料循环尿素流化床造粒技术),与该公司老装置的海德鲁流化床造粒技术(传统流化床造粒技术)相比,存在诸多的不同点,本文主要依据该公司两种工艺技术的工艺特点、运行情况和使用体验等方面,对两种工艺技术的工艺流程、运行原理等进行介绍和对比,并分析CRT造粒技术节能降耗的地方,同时指出了该技术的先进之处及不足之处。GGT(Hefeng) CRT technology(cold material circulating urea fluidized bed granulation technology) is adopted for the small and medium-sized granular urea granulation unit of offshore oil Fudao Company. Compared with the hydro fluidized bed granulation technology(traditional fluidized bed granulation technology) adopted earlier by the company, there are many differences. This paper mainly introduces and compares the process flow and operation principle of the two process technologies based on the process characteristics, operation conditions and use experience, analyzes the energy saving and consumption reduction of CRT granulation technology, and points out the advantages and disadvantages of this technology.
