摘要
介绍了中国石化安庆分公司蜡油加氢装置与催化裂解装置的生产运行情况,分析了蜡油加氢精制后对催化裂解装置运行的影响。结果表明:混合蜡油经加氢精制后可以作为优质的催化裂解原料;催化裂解装置产物分布得到显著优化,轻质油收率提高2.89百分点,干气、焦炭等低附加值产物收率下降明显;产品质量显著改善,催化裂解汽油的硫含量、诱导期、烯烃含量、芳烃含量均能达到国Ⅲ排放标准对汽油的要求。
The operation of gas oil hydrotreating unit and deep catalytic cracking （DCC） unit of SINOPEC Anqing Branch is introduced and the influence of hydrotreated feedstock on the operation of DCC unit is analyzed. Results show that the hydrotreated mixed gas oil can be used as a high quality feedstock for DCC unit. The product distributions of DCC unit is improved remarkably： light oil yield increases by 2.89 percentage point, and the yields of dry gas, coke and low value products decrease significantly. Meanwhile, the quality of products is improved greatly as well, items including sulfur content, induction period, olefins content and aromatics content of DCC gasoline can meet the specifications of gasoline for national emission standard Ⅲ
