介绍了添加剂强化重油蒸馏以提高减压蜡油拔出率的理论和实践。内容包括 :重油蒸馏的强化机理 ;强化蒸馏实验装置及其误差分析 ;采用强化剂 T1 1 8和 T2 1 8强化蒸馏胜利常压渣油的实验结果 ;所得减压馏分油VGO的 FCC实验结果以及减渣的质量对比。结果表明 ,添加 5 0 μg/ g T1 1 8或 5 0 μg/ g T2 1 8可分别提高 VGO拔出率 1 .3 %或 2 .2 % ,具有技术经济可行性。
The theory and practice of adding heavy oil distillation to improve the extraction rate of vacuum oil are introduced. The contents include: strengthening mechanism of heavy oil distillation; strengthening distillation experimental device and its error analysis; adopting intensifier T1 1 8 and T2 1 8 to enhance the experimental results of VGO distillation residue; FCC experimental results of the obtained vacuum oil VGO; Reduce the quality of slag contrast. The results showed that adding 5 0 μg / g T1 1 8 or 50 μg / g T2 1 8 could increase VGO pull-out rate 1.3% or 2.2% respectively, which was technically and economically feasible.
