渣油加氢装置高效运行的影响因素及应对措施

INFLUENCE FACTOTS FOR HIGH EFFICIENT RUNNING OF VRDS UNITS AND SOLUTIONS

针对影响渣油加氢运行的主要因素,中国石化石油化工科学研究院提出了相应的解决方案。为延长装置运转周期,开发了活性和稳定性更高的催化剂以及原料适用性更好的催化剂级配技术;为发挥催化剂的整体性能,开发了高效的反应物流分配技术;为进一步延长装置运转周期,开发了保护反应器可切换的固定床渣油加氢技术。

To extend the life cycle of VRDS unit,measures were proposed by RIPP base on the analysis of factors affecting the VRDS operation.Catalysts with higher activity and stability as well as better grading catalyst filling technology for varies feedstocks are developed.The higher efficient fluid distribution technology and an asymmetric switching guard reactor configuration are also developed to give full play to the performance of the whole catalysts system.
