Abstract:

This paper introduced two main paths of refining to chemical transformation at present stage-crude oil producing maximum chemical feedstock and direct crude oil steam cracking for producing chemical feedstock. State-of-art technologies and individual characteristics were included. China’s overall market state of refining and chemical products was also analyzed from the perspectives of supply and demand. The conclusion of this paper was that as the olefins and aromatics production capacity growing rapidly along with diversified and lower cost feedstock, the contradiction of refining to chemical raw materials transformation was emerging. At the same time of refining and chemical integration, base production and intelligentization, companies still needed to follow the guiding principle of maximizing profit, and took individual characteristics, position, logistics and regional market environment into consideration. How to reduce maximum feed cost, improve product value and increase production efficiency were the refining and chemical transformation development trend in China at present and some time to come. And it was also a grand challenge faced by Chinese refining and chemical industry.

摘要：

介绍了现阶段炼油向化工转型的两个主要途径——原油最大化生产化工原料和原油直接蒸汽裂解生产化工原料，阐述了各工艺的发展现状和特点，并从供需两个层面分析了我国炼化行业的总体市场态势。结论认为，随着烯烃、芳烃产能的快速增长以及来源路线的多元化、低成本化，“炼油向化工原料转型”的矛盾将会显现；企业在炼化产业一体化、基地化、智能化升级的同时，还是要以效益最大化为指导思想，充分结合自身特点、定位、物流以及区域市场环境等因素进行综合考虑，如何最大程度地降低原料端成本、提升产品端价值以及生产过程的效率才是目前及未来一段时间我国炼化行业转型的发展趋势，也是我国炼化行业面临的巨大挑战。
