原料性质对连续重整装置能耗的影响

INFLUENCE OF FEED PROPERTIES ON THE ENERGY CONSUMPTION OF CONTINUOUS CATALYTIC REFORMING

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 consump- tion was proposed based on the analysis of reforming reaction process and mathematical regression meth- od. 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.
