摘要
结合催化裂解工艺的特点对"能量三环节"模型进行了适当的修正,通过对全装置能量转换传输环节、能量利用环节、能量回收环节开展能量流的统筹核算,完成催化裂解工艺能量流应用效果的定量评估,从中发现了装置节能的方向,并发掘出多项节能措施。通过近年来的陆续改造与操作优化,催化裂解工艺的能耗进一步降低,从2005年的4095 MJ/t降低到2009年的3784 MJ/t。
The three-link energy analysis model was modified based on the characteristics of deep catalytic cracking （DCC） process and it was used to evaluate the energy flow utilized efficiency of DCC process quantitatively. Through completely calculating the energy exchange transfer link, energy utilization link and energy recovery link of the unit, the ways of energy saving were found and more than thirty countermeasures were proposed. These proposed measures were gradually realized in recent years, as well as the operation of the unit was optimized, thus the energy consumption of DCC process was further reduced from the 4 095 MJ/t in 2005 to 3 784 MJ/t in 2009.
