为了更加合理地反映原料性质对连续重整装置能耗的影响,以KBC公司的REF-SIM反应动力学模型和Petro-SIM流程模拟软件为工具,基于对重整反应过程的分析和数学回归方法,提出了一种新的关联原料性质与装置能耗的原料评价指标R(A/(N+P)).结果表明,与芳烃潜含量、芳构化指数等常用原料评价指标相比,原料表征指标R与装置能耗呈现较好的关联性,在相同产品辛烷值要求下,可以作为不同连续重整装置之间能效对标的基础评价参数.%With REF-SIM kinetics reaction model of continuous catalytic reforming (CCR) and Petro-SIM process simulation software, a new index, R(the ratio of aromaticsmass fraction to the mass fraction of naphthene and paraffin in the feed), of feed properties associated with unit energy consumption was proposed based on the analysis of reforming reaction process and mathematical regression method. It shows a good correlation between the new feed index R and unit energy consumption, better than that of the conventional feed index, potential aromatic content or aromatization index. Under the same octane requirement of product, the new feed index R can be used as a basic evaluation parameter when benchmarking energy consumption of different CCR units.
