【摘要】 某公司重油催化裂化装置采用MIP技术改造后能耗下降,其主要原因是由于反应需热减少、输出蒸汽量增加。采用能量转换与传输、工艺利用和能量回收三环节模型对该装置的能量平衡和有效能进行计算,分析装置目前能量利用的合理程度。结果表明,该装置的能量回收环节仍有较大的节能潜力,需进一步提高再生器及烟气能量回收系统的能量利用效率。根据计算和分析结果探讨该装置进一步的节能措施。更多还原

【Abstract】 By comparing the energy consumption of a FCC unit processing heavy feed prior and post to revamping with MIP technology,it can be seen that the energy consumption post to revamping is declined due to the decrease of required reaction heat and the increase of steam output.The energy balance and exergy balance are computed and analyzed using three-link model which including energy exchange and transmission link,technology utilization link and energy recovery link.Results show that in the energy recovery link of the unit,potential energy saving space still could be found,such as improving the energy utilization of regenerator and flue gas turbine.Some suggestions for further energy conservation of the unit are discussed and proposed.更多还原
