LTAG技术对蜡油加氢装置的影响及分析

中国石化洛阳分公司采用中国石化石油化工科学研究院开发的LTAG技术,在蜡油加氢装置和Ⅰ套催化裂化装置中进行了应用。结果表明:通过优化蜡油加氢装置分馏运行模式,使加氢柴油抽出量在25t/h左右,比设计值4.4t/h提高约21.6t/h,石脑油终馏点控制在155~175℃,能耗也控制在250 MJ/t左右;催化裂化汽油收率上升了5.86百分点,柴油收率下降了4.92百分点;柴汽比降至0.78,比投用前降低0.3个单位,说明该技术对降低柴汽比有显著的效果。

APPLICATION OF LTAG TECHNOLOG IN WAX OIL HYDROTREATING UNIT

LTAG technology developed by SINOPEC Research Institute of Petroleum Processing was used in the wax oil hydrotreating unit and FCC unit in SINOPEC Luoyang Company. The results show that the amount of hydrotreated diesel as FCC feed, drawing from the optimized fractionator in hydrotreatment system, reaches 25 t/h, more than the design value of 4.4 t/h. The end point of naphtha can be controlled in 155-175 ℃ range and the energy consumption is kept at about 250 MJ/t. The yield of FCC gasoline increases by 5.86 percentage points and the yield of diesel decreases by 4.92 percentage points. The diesel-gasoline ratio reduces to 0.78, 0.3 lower than before using LTAG technology, indicating a significant effect of the technology on reduction of diesel-gasoline ratio.
