流化催化裂化装置是现代炼油厂的重要二次加工装置之一,在加工过程中,需要消耗大量的动力和热能,但同时又有大量的能量随着再生器的烟气而被白白放空。国外在催化裂化能量回收方面进行了长期的试验研究工作,并已成功地在工业装置上广泛采用烟气轮机能量回收系统。我国上海炼油厂等单位也早在1970年开始这项试验研究工作, Fluidized catalytic cracking unit is one of the important secondary processing units in modern oil refineries. During the process, it needs to consume a large amount of power and heat, but at the same time a large amount of energy is emptied with the regenerator flue gas. Long-term experimental studies have been carried out on the energy recovery of catalytic cracking in foreign countries and the flue gas turbine energy recovery system has been widely used in industrial installations. China’s Shanghai refinery and other units as early as 1970, began this pilot study,
