随着原油的重质化以及轻质油品需求量的增加,延迟焦化增加液体收率技术将受到更广泛的关注。通过优化操作工艺、添加助剂、掺炼乙烯焦油或催化油浆等方法,可提高延迟焦化装置液体收率。综述了焦化装置增加液体收率的措施,重点介绍了添加助剂方法,并对其工业化应用前景进行了展望。 With the heavy crude oil and light oil demand increased, delayed coking increase liquid yield technology will receive more attention. By optimizing the operation process, adding additives, blending ethylene tar or catalytic slurry and other methods, can improve delayed coking liquid yield. The measures to increase liquid yield of coking unit were reviewed. The methods of adding additives were introduced emphatically. The prospect of industrial application was also prospected.
