摘    要:基于中国石油四川石化有限责任公司新建的2.5 Mt/a催化裂化装置节能降耗的考虑,通过设计和运行中对焦炭产率、电耗和蒸汽产量进行节能优化措施,四川石化催化裂化装置一次开车成功运行12个月后,各项指标能耗与设计值相比均有不同程度的降低,其中烧焦单位能耗下降0.080 8 GJ/t;电耗单位能耗下降0.030 1 GJ/t;4.0 MPa蒸汽产出单位负能耗增加0.041 GJ/t,装置综合单位能耗总体下降0.124 GJ/t。按照装置实际加工量2.5 Mt/a计算,加工成本可降低4 750 万元/a,节能效果明显,经济效益显著提高。

ANALYSIS AND APPLICATION OF ENERGY SAVING MEASURES FOR 2.5 Mt/a FCC UNIT
Abstract:The measures for optimal energy saving were suggested and applied for a new 2.5 Mt/a FCC unit of Sichuan Petrochemical Co. Ltd.. The measures for energy saving optimized the coke rate, electricity consumption and steam production both in design and operation. The actual energy consumption after 12 months operation reduced significantly compared with the design values. The unit energy consumption of coking, electricity and 4.0 MPa steam production is reduced by 0.080 8 GJ/t, 0.030 1 GJ/t, and 0.041 GJ/t, respectively. The overall energy consumption of the FCC unit decreases by 0.124 GJ/t. The processing cost for the 2.5 Mt/a FCC unit can save ¥7.5 millions/a. Both the energy saving and the economic efficiency are significant.
