Abstract: A large-scale heavy oil integrated refining technology of vacuum distillation column is presented in this paper. With the application of this technology，the capacity of the third atmospheric/vacuum distillation unit of a refinery was increased from 4.0 Mt/a to 6.0 Mt/a. After revamping，the running was satisfactory. In addition，various quality targets of the unit reached the requirements of design.

摘要： 介绍了自行开发的稠油炼制减压分离过程大型化关键集成技术。该技术成功应用于某石化公司第三常减压蒸馏装置，并使其处理能力从4.0 Mt/a提高到了6.0 Mt/a。改造完成后，各侧线产品质量均达到了质量控制指标，特别是作为加氢裂化原料的减二、减三线产品中Fe离子浓度降到0.3×10^－6以下，取得了良好的效果，产生了可观的经济效益。
