摘要
以某催化裂化装置吸收稳定部分为例,对催化装置吸收稳定部分能耗情况进行了Aspen模拟分析,考察了塔板数、进料温度、冷热进料方式对能耗的影响。结果表明:在脱吸塔板数40层,进料温度65℃、70%的热进料至35层塔板,30%的冷进料至塔顶;以及稳定塔板数52层、进料温度134℃的条件下,按能源折算值52.42 GJ/h计算,能耗(标油)比优化前减少了2.13 kg/t原料。
Taking aFCC unit as an example,this article analyzes the energy consumption of its gas concentration section using aspen simulation,and investigates the influence of tray number,feed temperature and feed mode on energy consumption.The results show that for stripper,when tray number is 40and feed termperature is 65℃,70% of the hot feed goes to tray No.35and 30% of the cold feed goes to the top of the tower.For debutanizer,when tray number is 52and feed termperature is 134℃,energy is saved by 2.13kg(standard oil)/ t(feed oil).
