摘要
冷滤点是衡量柴油低温性能的重要指标,最为接近柴油实际的最低使用温度。对中国石油兰州石化公司炼油厂2015年2套柴油加氢装置精制柴油冷滤点受到原油结构变化影响而出现的阶段性偏高问题进行了分析研究,通过大量数据统计与分析后,采取了降低常减压蒸馏装置常三线油95%馏出温度和对减压塔塔顶油进行脱蜡的措施,优化了柴油加氢装置的原料组成,最终有效地降低了精制柴油的冷滤点,为储运厂成品柴油合格出厂创造了有利条件。
Cold filter plugging point（CFPP） is an important index for diesel quality,which can reflect the actual performance of diesel engine at low temperature. The reason analysis for the higher CFPP of diesel fuel produced in the two diesel hydrofining units of Lanzhou Petrochemical Company in 2015 was conducted. It was recognized based on the data analysis that the cold filter plugging point of diesel fuel was affected by feedstock composition. Two measures then were adopted： reducing the 95% distillate temperature of No. 3 side stream of atmospheric and vacuum distillation unit and dewaxing the tope fraction of vacuum distillation tower to optimize the feedstock for diesel hydrofining devices, resulting in qualified CFPP of diesel fuel, which is of benefit to the blending factory for the storage and market of qualified diesel fuel.
