摘要
针对催化裂化汽油吸附脱硫S Zorb技术在国内外原有装置运行中暴露的问题,中国石化工程建设公司在S Zorb技术国产化改进过程中结合在炼油与化工工艺工程技术方面积累的工程设计经验和专有技术进行技术移植与创新,成功开发和应用反应器降尘器,改进再生系统、原料与反应产物换热器、闭锁料斗及吸附剂输送系统等。首批7套国产化装置顺利建成投产,剂耗、能耗、开工周期等普遍优于原有装置,初步形成新一代S Zorb技术,为中国石化汽油质量升级提供了技术基础。
To rization （S Zorb） eliminate the factors affecting the stable operation of FCC naphtha adsorptive desulfu units, based on the accumulated experience and know-how in refining and chemical en gineering design, SINOPEC Engineering Incorporation applies various technology innovations and trans- plantations in the localization of the first seven S Zorb units, such as developing a dustfall device for re- actor to prolong the service life of back-flush valve, improving regeneration system to solve the caking of adsorbent, arranging feed/reactant heat exchangers in parallel two-row to maintain continuous opera- tion, and adopting lock hopper control system to ensure the transport of adsorbent smoothly. After completing design and construction, these units go on stream successfully and their operation cycles pro- long significantly, furthermore, their adsorbent consumption and energy consumption are reduced as compared with base case, which indicates a new generation of S Zorb technology is developing to support the upgrade of gasoline quality.
