介绍了原油蒸汽裂解技术和重油催化裂解技术的主要进展,在此基础上开展了原油蒸汽裂解和重油催化裂解技术的集成创新应用研究,形成了集成裂解新技术。以该技术为基础进行集成创新的炼化耦合新工艺与传统炼化一体化加工工艺相比,前者具有装置构成优化、加工流程短、原油资源需求少、乙烯和丙烯收率高等显著优势,且裂解原油°API越高,其优势越明显。集成创新的炼化新工艺适应新型炼化一体化项目建设,也适用于现有炼油厂的转型升级,可实现最小化地生产成品油、最大化地生产化工产品的目标,由于油品收率非常低,可以很好地解决成品油市场严重过剩的难题。因此,基于裂解技术构建的高效集约型炼化耦合新工艺为炼化企业提供了实现“减油增化”目标的重要解决方案,将成为我国新型炼化企业建设和现有炼油厂转型升级的重要技术保障。

The main progress of crude oil steam cracking technology and heavy oil DCC technology are introduced.The integrated and innovative application of crude oil steam cracking and heavy oil DCC technology is studied,and a new DCC integration technology is developed.Compared with the process of traditional refining and petrochemical integration technology,the innovative coupled refining and petrochemical process based on the DCC integration technology has the advantages of optimized unit configuration,short process flow,low crude oil demand,and high ethylene and propylene yields.The higher API gravity of DCC feed oil is,the more obvious the advantages are.This innovative coupled refining and petrochemical process is applicable for not only the construction of new refining and petrochemical integration projects,but also the transformation and upgrading of existing refineries.It can be used to minimize the production of fuel oil and maximize the production of chemicals,which can help solve the problem of fuel oil oversupply.Therefore,the new intensive refining and petrochemical process based on DCC integration technology is an important solution for the refining and petrochemical enterprises to achieve the goal of“more chemicals with less fuel”,and will become an important technical guarantee for constructing new refining and petrochemical enterprises and the transformation and upgrading of existing refineries in China.
