摘要
比较了通过采用脱己烷塔切除C6组分和优化调整预加氢预分馏塔来降低苯前身物的两种降低重整稳定汽油苯含量的生产方案,采用后者可以使重整装置的综合能耗降低147.97 MJ/t,重整汽油收率提高7.36百分点,装置总液体收率提高0.69百分点,气体和损失降低0.35百分点,产品经济效益每月增加578.34万元。并对预分馏塔系统的进一步优化提出了合理化解决措施。
Two pathways （the dehexanizer and the feed prefractionation） for reducing the benzene content in stabilized reforming gasoline were compared. It is found that the comprehensive energy consumption of the reformer unit decreases by 147.97 MJ/t through feed prefractionation, the reforming gasoline yield increases by 7.36 percenfage points, and the total liquid yield increases by 0.69 percenfage points, gas and the loss reduce by 0.35 percenfage points. The economic benefit increases by 5. 783 4 million Yuan per month, and suggestions for further optimization of the prefractionation system are put forward.
