摘　　要：论述了常减压装置采用深拔技术的主要条件及手段,包括减压塔塔顶真空度、全塔压降、减压炉出口温度等。采用Petro-SIMTM软件对减压炉的模拟结果表明,提升减压炉出口温度能明显提高减压总拔出率,且减压炉有较大提温余地。工业实践结果表明,将减压炉出口分支温度由394℃提高至404℃后,渣油(含洗涤油)收率下降1.82个百分点,渣油530℃馏分质量分数下降1.08个百分点,减三线产出油终馏点提高10℃,且装置运行稳定,产品质量完全满足二次加工装置对原料的要求。The main conditions and measures of deep-cut technology were discussed including the pressure of top vacuum tower,total pressure drop,outlet temperature of vaccum furnace et al in crude oil unit.The vaccum furnace was simulated by using Petro-SIMTM software.The results showed that the total yield could increased evidently with the outlet temperature of vaccum furnace increasing,and there was room for the outlet temperature raising.The application results indicated that when the temperature of outlet branch ...
