摘　　要： 针对催化汽油辅助提升管改质降烯烃技术(ARFCC)存在能耗偏高的特点,采用'三环节'模型和经济理论对辅助系统的用能状况进行了研究,提出了以优化的辅助分馏塔热量为热源,粗汽油为主要热阱的换热网络,以最大限度地提高辅助分馏塔能量的利用效率,实现粗汽油气相进料的汽油改质过程的能量优化。研究表明:通过降低辅助提升管油剂接触温差,将辅助分馏系统的较低品质热量转换成等量的反再系统高品质热量,可达到催化裂化装置的能量升级利用;并使油剂混合过程中的损降低85%;回收环节的回收率从44%提高到57%,从而降低了汽油降烯烃改质过程的能耗。 In view of the high energy consumption of the auxiliary riser FCC （ARFCC） process, the current energy utilization of auxiliary system was analyzed through the application of the three-links model and exergy economic theory. A method was put forward for making the best of the auxiliary fractional column energy and making sure that the crude gasoline can be feed-in auxiliary riser line reactor in gas phase through the heat exchange network （HEN） using the energy of optimized auxiliary fractional column as heat resource and crude gasoline as heat well to optimize upgraded the energy of the gasoline modification process. The study indicated that the energy utilization was by reducing the temperature difference of catalyst and gasoline, and using the equal-quantity higher quality energy of the Reactor ＆ Regenerator System, instead of lower quality energy of the auxiliary fractional system. The exergy loss of mixing catalyst and gasoline in auxiliary riser line reactor decreased by 85%, and the exergy recovery rate of energy recovery link increased from 44% to 57%, thus reducing the energy consumption of FCC gasoline olefin reduction process
