摘　　要：介绍了首套采用国内自主催化蒸馏模块技术的500kt/a催化裂化轻汽油醚化装置的应用情况,结果表明:醚化反应器C5活性烯烃转化率达到73.37%,远高于设计保证值60%;装置整体的C5活性烯烃转化率为93.42%,达到设计保证值93%;C6活性烯烃转化率也高达65.65%,醚化效果良好;经醚化装置处理后,轻汽油的辛烷值(RON)提高2.6个单位,烯烃体积分数从68.2%降至29.2%,降幅达39.0百分点,轻汽油饱和蒸气压降低35.3kPa,醚化工艺可以有效降低汽油的烯烃含量、蒸气压并提高其辛烷值,有利于提高全厂高标号汽油的比例,每年可将60kt的甲醇转化为汽油组分,经济效益显著。The application of the first set of FCC light gasoline etherification device with capacity of500 kt/a in CNPC Guangxi Petrochemical Company was introduced,which adopted an independent catalytic distillation module technology.The results showed that the C=5 conversion in the etherification reactor reaches to 73.37%,higher than the design guarantee value 60%.The total C=5 conversion of the whole unit is up to 93.42%,close to the design guarantee value 93%.The C=6 conversion is 65.65%.The RON of the etherified light gasoline increases by 2.6 units with a decrease of olefin from 68.2%(φ)to 29.2%(φ).The saturated vapor pressure of the light gasoline is reduced by 35.3 kPa,indicating that the etherification process is conducive to improve the proportion of high-grade gasoline.The 60 kt/a methanol can be converted into gasoline component and the economic benefit is remarkable.
