摘要: 为了进一步掌握装置的运行性能,对中国石化海南炼油化工有限公司2.48Mt/a柴油加氢改质MHUG-Ⅱ装置生产满足国Ⅳ和国V排放要求清洁柴油(简称Ⅳ柴油和国Ⅴ柴油)的长周期运行情况进行了分析和预测。该装置自开工至2015年6月30日,生产国Ⅳ柴油的时间累计479天,生产国Ⅴ柴油的时间累计146天。运转分析结果表明,改质反应器中精制和改质催化剂平均失活速率分别为0.015℃/d和0.042℃/d,精制反应器中催化剂平均失活速率为0.055℃/d,两个反应器的总压降上升速率为6.4×10-4MPa/d。综合考虑原料性质和组成的变化、国Ⅳ柴油和国Ⅴ柴油轮换生产对催化剂寿命的影响以及反应器压降等因素,预测出精制反应器催化剂可再运行620天,即催化剂总运行时间可达3年以上。

Abstract: In order to further understand the performance of running, analysis and forecast ofhainanrefining &chemical Co. Ltd. SINOPEC 2.48Mt / a diesel hydro-upgrading MHUG-Ⅱ,it products to meet the Ⅳand V clean diesel long-term operation. Go into operation to June 30,2015,product Ⅳ accumulated 479 days, V diesel accumulated 146 days. Operation analysis shows that the reactorof hydro-upgrading and reforming catalyst deactivation average rate was 0.015℃/d and 0.042℃/d, refining reactor catalyst deactivation average rate was 0.055℃/d, two reactors total pressure drop rise a rate of 6.4×10-4MPa/d. At the same time considering the nature of raw materials and processing changes in the proportion, the product Ⅳ&V rotation effect the catalyst life and reactor pressure drop. To predict the refining reactor catalyst then run 620 days to reach the regeneration cycle or exchange.
