摘　　要：为进一步解决催化裂化油浆出路问题,中石油云南石化有限公司利用延迟焦化装置进行了高比例掺炼催化裂化油浆的试验。结果表明,油浆掺炼比例(w)由25%上升至29%时,石油焦收率明显下降,蜡油收率有所提高,轻油收率、总液体收率均有所升高,石油焦的挥发分、灰分分别提高了1.90百分点和0.04百分点,石油焦的硫质量分数降低了0.10百分点,高比例掺炼前后石油焦均满足企业4A级标准。同时发现,高比例掺炼加速了加热炉进料泵管线的腐蚀,但对焦化装置的工艺操作条件影响较小,加工每吨原料产生的经济效益提高67.0元,表明在优化方案下高比例掺炼催化裂化油浆具有可行性。In order to further solve the usage problem of catalytic cracking(FCC)slurry,the test of high-proportion blending of FCC slurry was carried out in the delayed coking unit of PetroChina Yunnan Petrochemical Company.The results showed that when the blending ratio of FCC slurry increased from 25%to 29%,the yield of petroleum coke decreased significantly,the yield of gas oil increased,and the yield of light oil and total liquid increased.The volatile matter and ash content of petroleum coke increased by 1.9 percentage points and 0.04 percentage points,respectively,and the sulfur content of petroleum coke decreased by 0.1 percentage point.The petroleum coke before and after high proportion blending could meet the 4A grade of enterprise standard.At the same time,it was found that the high proportion blending only accelerated the corrosion of the feed pump pipeline of the furnace,and had little effect on the process operation conditions of the coker.The economic benefit of processing per ton of raw materials was increased by 67.0 Yuan,indicating that it was feasible to blend FCC slurry with high proportion under the optimized scheme.
