摘要
基于渣油加氯-催化裂化双向组合技术 RICP 中小型开发和工业应用结果,探讨了 RICP组合技术中催化裂化操作单元的作用、所受的影响及其调整措施。在 RICP 组合技术中,催化裂化装置是重油得以最终转化为产品的操作单元,同时提供低粘度、高芳香性的 HCO 和/或澄清油等中间物流作为渣油加氢装置的进料组元之一。RICP 双向组合技术能够改善催化裂化操作单元的进料性质,提高催化裂化装置的加工能力或掺渣率,同时改善产品分布和产品性质,提升催化裂化装置的综合效益。采用 RICP 技术对催化裂化操作单元中进料体系、加工能力、产品分布和性质、操作模式、分馏系统、催化剂体系造成多方面的影响,应进行相应的调整,以发挥 RICP 组合技术的优势。
Based on the development and commercial application of RICP technology（Residue Integrated Combination Process） ,the investigation on the function and adjustment of FCC unit in RICP was carried out. In RICP technology, FCC unit not only is the final process for residue conversion,but also provides intermedium streams, such as heavy cycle oil （HCO）and/or decanted oil （DO）, as cofeedstock for hydrotreating unit. The new recycle mood of HCO and/or DO stream results in a great improvement of FCC feedstock properties, which leads to the increase of throughput and/or residue blended ratio of FCC unit,and the product slates and product quality are improved as well. In respond to the changes in feedstock system, unit capacity, product distributions, product properties, operation mood, fractionation system and catalyst system, proper adjustments should be made in FCC process to obtain the optimal effect of integrated technology.
