摘要: 在多重发展压力的持续叠加下,传统炼油行业转型升级迫在眉睫。为了充分发挥石油中不同结构分子及组分的最大价值,经济高效生产高附加值产品,组分炼油成为帮助石化行业快速转型升级以及迈向分子炼油的重要方向。通过与传统馏分炼油对比,对组分炼油挖掘原油特定组分与目标产品间的重要关系,以及组分炼油的实施步骤和关键支撑技术进行了分析,并对其在提高原油资源利用率与产品附加值、降低生产成本与碳排放、新材料开发等方面的作用进行了深入研究。在组分炼油方案中,乙烯产品收率和吨原油效益可分别提高约12.7%和160.12元,吨原油二氧化碳减排量约为19.83 kg。本研究可为分离技术和关键炼油技术未来发展与应用提供重要参考,助力石化行业实现低碳转型升级目标。

Abstract: Under continuous superposition ofmultiple development pressures, the transformationand upgradingof traditional refining industry is imminent. In order to make full use of the value from different molecular and component in crude oil and produce high value products economically and efficiently, the research of component-based refining has become an important direction to helpthe petrochemical industryto upgrade rapidly and move towards molecular refining. By comparing with traditional refining (fraction-based), the important relationship between specific components of crude oil and the target products,the implementation steps and key supporting technologies of the component-based refining were analyzed, and theeffects on increasing utilization ratio of crude oil resources and added value of products, reducing production cost and carbon dioxide emission and developing new materials were studied. In different component-based refining cases, the yield of ethylene and the benefit per ton of crude oil could be increased by 12.7% and 160.12 Yuan/t, respectively,and thecarbon dioxide emission reductionwas about 19.83 kg per ton crude oil. This study provides an important reference for the development and application of separation technology and key refining technology in the future.
