摘 要: 以基准物流图研究法为基础，建立一种能够分析复合流程工业中物流对能耗的影响分析模型。并以某氧化铝厂1999年生产数据为依据，采用该模型分析复合流程中偏离基准物流图的各股物流(包括从外界输入的物流α、回收进行再处理的不合格产品或副产品β以及向外界输出物流γ)对折合比、工序能耗和最终产品综合能耗的影响。

Abstract:Based on the method of standard material flow diagram (SMFD), a model for analyzing the effect of material flows on the energy intensity in complex process industries was established. Based on the statistical data from an alumina refinery plant in 1999 with Bayer complex process, the effect of each material flows deviating from SMFD (including input material from surrounding α, recycle unqualified and waste product for retreatment β and output wastes to the surrounding γ) on the product ratio, unit process energy intensity and energy intensity of the final product in complex process industries can be analyzed clearly using this model.
Key words: complex process; energy intensity; material flows; process industry
