摘要
介绍了炼厂催化裂化装置实施的多项节能改造措施,其中催化裂化装置顶循油作为气分装置脱丙烷塔底重沸器热源,节约低压蒸汽5.6 t/h,常压蒸馏装置常压渣油进催化由冷进料改为热进料,使催化装置多产中压蒸汽7 t/h,催化装置低温热水系统增加热阱负荷,减少循环水消耗433 t/h。因此,每年可增加效益2 592.6万元。
Several energy saving measures for the FCCU are introduced in the refinery. Among them, FCCU top cycle oil is used as the reboiler heat source of propane separation tower in Gas Separation Unit, saving lowpressure steam 5.6t/h; The atmospheric residue from atmospheric distillation unit is fed into FCCU as hot feed instead of cold feed, raising medium-pressure steam production by 7t/h; And heat sink load of FCCU's lowtemperature hot water system is increased, reducing circulating water consumption 433t/h. These measures can increase the refinery‘s income of 25.926 million RMB annually.
