利用自主开发的重油热反应评价仪,建立了能够反映焦化原料裂解和缩合特性的评价方法;根据国内典型延迟焦化装置焦化原料加工性能评价数据库,对4家生产企业所用焦化原料的加工性能进行了综合评价;另外,采用焦化炉过程模拟软件,对优化空间大的中海油惠州石化有限公司(简称惠州石化)焦化炉进行了模拟优化,提出了相应的装置加工优化建议。结果表明:与评价数据库典型原料对比,4种焦化原料的甲苯不溶物质量分数均较低,结焦倾向偏低,裂解难易程度属中高水平;将惠州石化焦化炉的单点注水改为多点注汽后,在单台炉进料量为42 t/h,焦化炉出口温度为503 ℃的条件下,原料在炉管内430 ℃以上反应停留时间由30 s延长到35 s。

An evaluation method which could reflect the cracking and condensation characteristics of coking feedstocks was established by adopting the self-innovated heavy oil thermal reaction evaluation instrument.The processing performances of coking feedstocks from 4 factories were evaluated by comparing the processing performance database of coking feedstocks in typical domestic coking units.The coking furnace of Huizhou Petrochemical Co Ltd,CNOOC,which had significant optimization space,was simulated by the coking furnace process simulation software and the corresponding optimization measures were proposed.The results showed that compared with the relevant data in the database,the mass fractions of toluene insoluble matter and coking tendencies of the four coking raw materials were low and the cracking ability of the four coking raw materials were at medium and high level.After changing the single-point water injection mode in coking furnace of Huizhou Petrochemical Co Ltd to multi-point steam injection mode,the reaction residence time of coking raw material above 430 ℃ in the furnace tube was extended from 30 s to 35 s,under the condition of feedstock quantity of single furnace at 42 t/h and furnace outlet temperature at 503 ℃.
