摘　　要：在原料性质相同、工艺流程与主要操作参数基本一致的前提下,将延迟焦化中试装置与典型工业装置进行对比分析。结果表明:中试装置的长径比为3 833,与工业装置的长径比(3 759)非常接近,虽然中试装置炉管内径为6mm,小于工业装置炉管内径(107mm),但也能按工业装置操作参数正常运转;进料油在中试装置焦化炉出口处的转化率、汽化率分别为6.1%和22.40%,略小于工业装置的7.8%和26.33%;中试装置焦炭塔高径比为6(塔内油气线速0.009 46m/s),大于工业装置的4.12(塔内油气流速0.098 20m/s),但仍符合工业设计推荐值不大于0.15m/s的要求。3种不同原料、3个不同循环比运转的实验结果表明,中试装置的产物分布及性质与工业装置相近。On the premise of the same raw material properties,process and main operation parameters,the comparison of the pilot plant results of delayed coking experiment with that of the typical industrial device are conducted.Although the inner diameter of the pilot plant coking furnace tube is6 mm,significantly smaller than that of the industrial device（id=107mm）,the length/diameter ratio of 3 833 is close to the industrial device 3 759,the pilot plant can operate normally like industrial unit,the furnace outlet temperature of pilot can reach 500 ℃.Feed conversion and gasification rate at the outlet of the coking furnace of the pilot are 6.1%and 22.4%,respectively,slightly less than the industrial unit 7.8%and 26.33%.The height/diameter ratio of pilot plant coking tower reaches 6（oil gas line speed 0.009 46m/s in coking tower）,more than the industrial device 4.12（oil and gas flow rate of 0.098 20m/s in industrial device）,but it is still in the recommended range of industrial design requirements（ 0.15m/s）.The test results which 3kinds of different materials and 3different circulation ratios show that the pilot plant product distribution and their main properties are very close to the industrial device results.
